I’m working on setting up a small system and I’m wondering if quikrete sand would work. I find two options there’s all purpose coarse washed sand which I believe is basically graded for masonary but it doesn’t specify or I can get quikrete pool filter sand. Would either of these be appropriate?
Some additional information generously provided by Dr. McMurtry:
On the Quikrete website there is a range of commercial sands. They are a “consistently graded, washed and kiln dried sand used for industrial and construction applications.” Available in coarse, medium and fine grade.
I’d suggest 3 parts #1963 + 2 parts #1962. … and personally I’d add 1 part #1961 for every 10 to 15 of the others (for added SSA)…
Bulk discounts most places. Also 8 to 12 times cheaper than clay ball BS
100#/cu ft. 40 bags = 1.5 cu yd…Local quarry price ~ $60-70/ cu meter + delivered within 160km. – Dr. McMurtry
Apply the coarser sands on the lower layers of the biofilter.
Nevermind. Price dictated using the all purpose sand. It’s $20 cheaper per 50 pounds. It’s a small system so no big loss if it doesn’t work well.
