  1. I have finished building my first experimental version using best sand i could find in my region which special ordered water filtration silica sand grated to custom sieves based on research. It was not cheap so i order 5 yards of it since cost of getting what i needed has not much price difference because it cost mostly to transport. So i had them max the transport capacity. My system has been running since june. I order 100 silver carp from nearest vendor. Half survived, half died due to stress heat and elevation changes during transport. So the vendor attempted to compensate with channel cat
  2. Hi Aufin, blasting sand is fairly expensive, twice or 3 times the price when purchasing from homedepo or lowes, and it will be another research project to find local provider for such quality sand. i think i will stick to the quarry order and get it processed this week. i feel i have done plenty research for the local source and ended up finding something 51 miles away. many can claim its easy to find sand, well not the right kind of sand that will #1 drain properly over time, #2 allow furrows to flood consistently, #3 provide oxygen as it drains retaining it to feed the good bacteria tha
  3. so i got a quote back for the spec combination which is a custom order. its pricey, however, its 5 yards, i might as well stock up on this sand if i am to continue to do IAVS with lack of good sources around. i dont know, the problem with local sources is their aggregate is fairly mixed of wide range or sand sizes across the spectrum. they dont exactly have consistent combination. in most cases their particle sizes are too fine. the pricing from local providers for random aggregate is 3 times less, however, getting consistent aggregate from homedepot, lowes in bags will be 500$ more ontop of w
  4. i am probably annoying the quarry sales person with my "custom" order questions for "small" 3 cubic yards of sand (comparing to what they order in minimum, around 20 cubic yards)
  5. Thank You Vkn, i have been in contact with quarry to see if any providers that order from them have similar aggregate of what you mentioned. i am definitely making sure i make the right choice without being too hasty
  6. Hi Gary, i have read this article before and partly agree. I agree on the part that i have plenty of "sources", from Lowes, Homedepot, to local providers, but not local quarries. i am looking for best option, and weighing in on what risks i should take. According to the article, it seems the fine white sand represents what he used. with exception that it looks like fine white sand looks more like crushed granite vs coarse quartz. the silt level also looks to be less than 8% comparing to other grades. the sizes seem to represent same % groups. if that is acceptable then i will just go with
  7. i am coordinating the logistics of sand delivery now, its definitely going to cost either way. however, i understand that the better sand is the sand necessary to have 100% full proof system. so i will take that risk and go forward with this. i have some friends willing to help me transport the product. we will see what happens over the course of next two weeks. in the mean time today i was using hammer drill to get through the final layer of my backyard "dirt" which is past 3.5 feet to bury my 300 gallon ibc tote for the central sump system where the two grow beds will drain and the pump
  8. i got a quote, $59.50 a ton. i need about 3 cubic yards so that will be around 7000 pounds which comes out to $416.50. this is also a quarry so i need to get my own 12 foot trailer to pickup the product vs paying 150$ an hour for delivery. loading is only monday - friday 6 AM to 2 PM. this will be interesting.
  9. here is what i got from sri. looks like the #12 is my sand to go with which is between 1 to 2 mm. #10 is almost 2 mm in size and maybe too large? if you had a choice between consistent 1.6 mm vs 1.9 mm what would you choose?
  10. i got a reply from sri, they are 51 miles from my location. asking about logistics and details about their products. looks like we may strike some deal.
  11. here is my sand analysis and source from original test: source: size: turbulence test: settling test over night: drainage test:
  12. i left sri a request on their website with requirements and my contact info. will see if they get back to me. if not i will contact them by phone. wish me luck!
  13. thank you! i have not seen this source. i will give it a try! i was almost going to settle on the fine white sand, however last night testing yielded similar results as neighbor with sand leaking through the holes and water being bit dirty containing what seems to be very fine particles yet possibly containing some silt/clay. so i was on fence to make that decision. i didnt want to spend 300$-400$ on 5 cubic yards of sand that will just be wasted. i guess not fully wasted since my kids will love to have gigantic sand playground. i am curious if neighbor ordered the sand from sri company a
  14. Hi!

    someone mentioned that you are near the sacramento area and also performed some research on sand source. i am curious if you found a proper sand source? if you did would you point me to the source? That would help me alot since i have already checked several providers and they are no go. 

    thank you in advance!
