  1. Hi again well you can exclude the tank/growbed then I still suspect the tap water, and/or clay pellets Tap water is manipulated and will often change in chemistry as it gass off. Clay pellets can be full of alkaline residues, deepending on type, brand, manufacture, often it's enoughf to wash it out. You will have to test it to find out. Lava rocks and rainwater is most often pH neutral or acidic, thats why I don't suspect them. cheers
  2. Hi Newbie Welcome to APN/HQ I doubt it's the lava rocks or rain water causing your rise in pH, it's more likely your clay pellets or tap water. You can check your media, by putting some in a glass of vinegar if it fizzes (bubbles) then you'w found one potential cause. Tap water often rise in pH as the co2 reeleases so if you measure it 24-48 houers after tapping it that might be it. Or maybe it's your fishtank growbed ? is any of them made out of cement ? If you can post some pics and give more details on building material etc.,it makes easyer for members to advice you. cheers
  3. Hi again You could try contacting TCLynx she haven't been on here fore some years so it might be easyer to contact her dierectly on her web site she runs a commercial "organic" AP operation in Florida. She use and sells the product in Q, and she is usually very helpfull IME cheers
  4. Hi Mikkel On online aquaculture recourses/courses I'w found this good IMO hands on or practcal training at a fishfarm, RD facility or with a conservation group is of equal value (even more) to the technical/theoretical skills you can achive online or in a class. It all goes hand in hand I guess This doc/pdf have references (last pages) to the regulations on aquaculture in DK Lett us know how you progress on the matter, and obstacles or problems to overcome, are just as interesting to learn/hear about as sucsess. Good luck ahead cheers edit to add another great online resource
  5. Hi again This might be a helpful link cheers
  6. Hi phri Neither is mine I agree local resources is often worth it's weight in gold and offcourse language is a key to understanding of the same value. Moses, there is a Malaysian siphon guru called Affnan, he has been in to aquaponics for years, and have a nice blog As far as I know/understand, Bahasa Melayu is closely related to Bahasa Indonesia, so Affnan might be a helpful resource to you ? And also this APN/HQ member/thread might have a sort of "local" value for you. cheers
  7. Hi again Moses You have to use known standards if you wan't serious answers to your Q's Either use the metric liter, US gallon = 3,78541178 litere, or Imperial gallon = 4.54609 litere, and inform wich it is. I suggest you read up in Garys Online Urban Aquaponics Manual I would get rid of the koi they are not suited to live (thrive) in such small aquarium/tank Also to look at more precice zises and readings/values/measures in general, EG: You say you have a pump that pumps 2000 liter/houer and a tank with 57 liter water so your pump is turning over the tank water 35 times/houer it should be more like, 1 to 2 times/houer. You say your Ph is 6.5-7ish, it's a huge difference between Ph 6.5 and Ph 7 (in particular in fast swings to the fish) I don't mean to disencoureage you but I fear you will fail fast unless you get the proportional numbers, volumes, zises, etc. in order. good luck cheers
  8. Hi Moses Welcome to APN/HQ 16 koi in how big a tank ? When ever you wash the filter, you are back to start on establishing nitrifying bacteria, so stop that like Toga said. cheers
  9. Hi again mikkei Iff you are in CPH it's a short trip to Malmø I'd like to go there my selfe next time i visit my brother in CPH cheers
  10. Hi Another pair of twins arrived this morning cheers
  11. I have no idea as to why the article link won't work ? i tried to edit it 5-6 times ? anyhow look it up here it's the article named "What is the nitrogen cycle and why is it important to Aquaponics?" by Kellen cheers
  12. Hi RS Yes it holds some truth. Have a look at this article on cycling Also this threads And this post/comment on iAVs cycling cheers
  13. Hi Shadders Welcome to APN/HQ Nice first post Keep up the good work cheers
  14. Hi Keightley Welcome to APN/HQ If the growbeds are kept so clean that the worms won't survive in them, the fish will be really happy. You should read AquaAuroras threads she is keeping goldfish in aquariums indoors here: and here: cheers
  15. Hi Bob Welcome to APN/HQ That is correct Yes that would be the way to calibrate your instrument see link here Sorry I can't help you with the calculations metrics is my language cheers
