Hey guys, I need some info. I am from TankOutlaws.com and I am restarting my 30 gal. I have flourite in my planted 10 gal but heard from a fellow member that I could use cat litter. So I got 3 7lb bags of the 98 cent litter from Walmart and put it in there with about a 1" cap of black sand/gravel. At it's deepest part the litter is around 4", I created a nice slope, and at it's shallowest the litter is 1". Once I got the substrate in order and started running my canister I got another message from that member stating that too much litter can cause a certain type of bacteria to crop up and kill the roots of my plants.
How much is too much litter and what have you guys used/been successful with?
