    Hi Jason Welcome to APN/HQ There are so many variations on flow design, so it's impossible to point at one specific pump type/brand. In principle you need a pump that can circulate the entire tank volume in 1-2 hours. So you need a pump that can move minimum 1500 l/h accounted for your designs headloss. There is a lot of discussions on the matter in "old" threads that might be helpful to read thru like these : cheers
  3. Hi Jejanov "my rule of thumb" is water change. Mainly for the fish health/welfare. Of course fish age/specie means there is a variety of tolerance to high nitrate, but it can take weeks to reduce the nitrate levels. So I would recommend to use some of your tank water in the garden, and then top up the tank. I assume your "fresh water" source, does not hold a high nitrate level ? cheers
  4. Hi Siddhu243 Welcome to APNHQ. Most probably you hurt the plant root, when transplanting it. You should grow the seeds in a small rockwool cube and transplant that into a larger one, or grow in coco coir, leca etc. Point is coriander (roots) does not like to be moved, so you move it with what ever media you seeded it in. cheers

    Hi DanielJ Welcome to APN/HQ cheers
  6. Hi bkardon Welcome to APN/HQ cheers
  7. I really wish you where wrong on this matter so sad cheers
  8. Hi BD Sad to observe and impossible not to know about if you read/watch any news outlets. I saw a interview with some Norwegians, when they arrived home for Christmas after a 2 week volunteer deployment in NSW fighting fires, alongside Brits & Canadians. I wish you guys down under all the best 🤞 cheers Seems to create some political turmoil cut/paste from here https://greenlemon.me/guy-posted-a-tweet-thread-that-reveals-the-devastating-power-of-the-australian-bushfires/ Guy Posted A Tweet Thread That Reveals The Devastating Power Of The Australian Bushfires By margareth January 4, 2020 It’s burning and still will for the next few months. More than a million acres of rainforest were burnt in Amazon, but that was not enough to turn the head of the people. Currently, more than 6 million acres of land has turned to ash in Australia with the fire showing no signs of stopping. Thousands of people are stranded on the beach and had to be evacuated by water and air as land access had been blocked with scorching fire. More than 400 million of wildlife creatures are gone, putting a huge dent on the native species. Since September 2019, New South Wales has been experiencing bushfire which quickly grew severe. The country was supposed to experience rainfall at this moment, but the wind had blown that rainfall elsewhere, causing the land to dry up. Green Lemonwishes to raise awareness on this incident and this man’s tweet did the trick. Bodie Ashton, a historian, took to Twitter to explain what is happening in Australia to the world. manwithoutatan manwithoutatan manwithoutatan He also shared the harsh fact that these firefighters not only risked their lives but also won’t get enough pay to support themselves and their families. manwithoutatan And then there’s the PM, Scott Morrison, who was blamed by many due to the crisis that is currently raging. manwithoutatan manwithoutatan The smoke from bushfire is also causing severe breathing problems and is equal to smoking a packet of cigarettes a day. manwithoutatan Australia is facing losses and emergency situations not seen in years. manwithoutatan manwithoutatan manwithoutatan manwithoutatan Approximately 1300 houses have been burnt with 20 killed, including 3 volunteer firefighters. Australia worst bushfire was in February 2009 dubbed the ‘Black Saturday’ with 180 deaths and more than 2000 houses gone. The spread is lightning fast as grass fire burns much faster than forest fires or the average running speed of a human. The size of bushfire in Australia is currently bigger than London. manwithoutatan manwithoutatan manwithoutatan Here’s another way to see how vast the destruction of the bushfire is. manwithoutatan Ashton added that the government should be addressing the climate change issue instead of relegating is as purely ‘political’. He further explained his points with more tweets under his thread. manwithoutatan manwithoutatan manwithoutatan Ashton explained that as an Australian historian living in Germany, he just wants to help people visualize better what’s happening in Australia. As severe as it is, people don’t seem to understand how it’s directly affecting a large number of people. But it is and it will. A third of the koala population has been burnt to death and experts are saying this could be the doom of native species on the land. Ashton added that the fire is affecting millions of people in Australia and there are volunteers fighting and racing against time to curb it. He finally emphasizes that we can all do something to help them and one way is by donating to organizations who directly fight against fire and provide medical aids to people and wildlife.
  9. Hi jw2264 Welcome to APN/HQ I did your survey, and moved your post to the general aquaponics discussion section. as many wan't read the post in the welcome wagon section cheers

    Merry Christmas

    Hi All Merry Christmas cheers
  11. Hi again Got it, it's a DWC system UVI style built on site. It can be used for either aquaponic or hydroponic so you don't have to use fish to run it. here is a description of what you got https://www.uvi.edu/files/documents/Research_and_Public_Service/WRRI/UVIAquaponicSystem.pdf From the pics it looks like it's nicely built so does the green house. here is some more info https://www.nal.usda.gov/afsic/aquaponics?page=1 https://www.agmrc.org/commodities-products/aquaculture/aquaponics http://factsheets.okstate.edu/documents/srac-5006-economics-of-aquaponics/ I would contact the local agricultural extension office https://extension.wsu.edu have a chat and ask their opinion cheers You might get some pro/con thoughts and ideas by plowing thru this thread
  12. Hi again Gundog I downloaded the file but couldn't see any thing (wouldn't open) Could it be a Nelson & Pade system ?https://aquaponics.com/aquaponic-systems/commercial-systems-3/ see if you can recognize it See if you can identify any brand names on the pics you got, if it is a commercial system the vendor might also offer support cheers
  13. Hi Gundog Welcome to APN/HQ To answer your Q's, you have to provide more details/pics type of setup "brand-names" etc.also what part(s) of the system is missing (25%) but I'll try to give a "general" answer. Not hard, if you are dedicated and are genuinely interested, experience and/or basic knowledge in either agri- aqua- culture or both would help. Time intensity will vary with "season". Keeping livestock will tie up some time on a daily basis, no matter how much you automat the system. It could be, however it deepens on numerous factors. The upside for you is the $300.000 invested (if it is put in a "good" system you can use?) You have to figure out how much more you need to invest to get it up and running. The cost of the remaining 25% does not necessary mean another $100.000 it could be more/less, pluss the cost of your own training time and fees? Water budget is the most important part, can you get enough ? any restrictions on supply ? Access to market is vital (distances & demands) ,also what can you grow in your climate? indoors/outdoors/heating/cooling/lighting etc.......? Regulations ? restrictions ? on fish species, supply of fish................. the list is long, there are a few threads on the subject worth reading. https://wsg.washington.edu/wacoast/meetings/June-2016/Handout-Overview of State and Federal Aquaculture Requirements.pdf Short answer to both is yes. No such thing as dumb Q's so don't worry cheers
  14. Hehe I see I got those pictures in a odd sequence I'll add that before proceeding to make the jelly, I did a test run as I'w never made jelly before. The test badge was made of mint picked in the garden, turned out really nice as well and boosted my confidence to make the rowan jelly cheers
  15. Hi again So I picked another +5kg badge for the freezer. Most recipes I found, recommended a mix with apples do to the bitterness of pure rowan jelly so that was the next step. First pick some apples and make juice tossed the apple juice in the freezer, next step pick up the frozen rowanberry and make rowan juice Then I went on with the actual jelly production I decided to make two different. One pure rowan, and one 50/50 mix rowan/apple and true enough the mix is indeed a sweeter jelly (but still bitter) I'm very happy with the final results both taste great I still have 4litre pure juice left in freezer, so I can make more jelly when needed, and also ended up drying a good lot of the rowan berries as well All in all very pleased with the harvest and final products cheers I use the same method on brussel sprouts, if harvested in summer/fall, before we have had a few frost nights. I always toss them in the freezer over night to sweeten them before use
  16. Hi again Hunter Pehrson Here is 2 links on the matter, you will see that the "ideal" varies a lot, depending on fish species tolerance to ph swings https://thefishsite.com/articles/water-quality-a-priority-for-successful-aquaculture https://www.dpi.nsw.gov.au/fishing/aquaculture/publications/water-quality-management/monitoring-alkalinity-and-hardness I just uploaded a pdf on your Q to the download section as well, since links seems to have a limited shelf life Keep in mind that fish husbandry is just the same in aquaponics, as it is in aquaculture cheers

    Alkalinity and Hardness in Production Ponds
  18. Hi Hunterpehrson Welcome to APN/HQ To answer your Q on alkalinity, I find it easier to point you towards a thread/post and a APN article where the complexity are pretty well explained IMO Quote : Here are the most common scenarios you will encounter that require adjustments: Declining pH - Generally speaking, you will want to maintain your cycled system pH around 6.8-7.2. If it falls below this range, the nitrifying bacteria will be adversely impacted. You need to add a base. There are commercially available products for this, but you can also use relatively common chemical salts like sodium bicarbonate, calcium bicarbonate, potassium bicarbonate, calcium hydroxide, calcium chloride and many others. Specific recommendations are beyond the scope of this article, but will be featured in a later article related to maintaining pH levels....................... cut/paste from this article : I recommend you read all the answers in the post and the full article cheers Edit: I'll add this link here as well: cheers
  19. Hi Mohamed Welcome to APN/HQ Sure you can use buckets, however the container you choose to use is not representing the main load, so I can't see how that will represent much of a weight reduction on a system ? The sand & water is what should be your main focus and/or concern regarding weight, and it is a really important point to be sure that the place you put it can handle the total load There is a few pictures of small "bucket size" systems in different threads/posts, @vkn have some nice ones in his trial thread IMO Here is one " EASY " You being from India I recommend reading the hole thread, let us know how you progress with however system you choose, good luck on the journey cheers
  20. Hi OneTree Welcome to APN/HQ Mine is fine as well, that is after the last forum upgrade cheers
  21. Hi I just had to harvest some rowan berries ( https://en.wikipedia.org/wiki/Rowan ) as the trees are really full of them around here, this year. They are really bitter and need to be frozen before use to release the sugar content . So I washed/cleaned them and got total 2,8kg berries for the freezer. Then I got on the net to find some recipes on how to make rowan jelly more to come cheers
  22. Hi Tam try this You can also use the search function (on the top right) just type in the word salt cheers
  23. Hi Tam When replying to posts, you do not use the report post button. That's for reporting spam abuse etc. , and can only be seen or read by moderators. I will copy your responses (in the 2 reports) to vkn & Toga here: Tam Submitted 5 hours ago Dear VKN, What temperature are you at? Do you have more turbidity due to the Silica dust? The temperature is 30 Celsius. I don't see turbidity from silicate dust so much. If it is not a lot, once essential microbes are established, the fish deaths rarely happen. What have you done to jump start the nitrification process? This picture show the way I used to raise bacteria. I use feed as source of ammoniac, bacteria I add in flour form. I add fish after nitrogen cycle is ok (nitrite is slow down 0.1; nitrate has increased more than 40 mg/l) on 7-Aug, Thank for your advice! Tam Submitted 4 hours ago Dear Toga, Thank for your help, Tomorrow I will follow your instruction, I will change water, add salt batch for cure fish, stop feeding, As I post to reply report to Vkn, I had create the nitrogen cycle before adding fish on 7-Aug, I willing to hear your help on my beginning small system, Thank Tam cheers
