So, I'm new to fishkeeping and am planning on stocking my 20 gallon with a male betta, some snails, and some ADFs. The tank has been running for a little while to cycle. Right now I have 30/60 and 40/80 grit black diamond blasting sand over some gravel. I thought this would be best for the african dwarf frogs I was planning to get, but now my water has been cloudy for the past three days. I'm beginning to think it won't ever settle down. It's so fine that when I try to move anything or do anything towards the bottom of the tank I end kicking up so much sand that just floats up like dust. I was wondering if anyone has any experience with ADFs on 20/40 BDBS? I really wanna use it because I like the look and it's very cheap but I worry that it will be too coarse for the sensitive froggies. Thanks in advance!!
