I recently got back into the hobby after I saw this thread and instantly wanted to create something similar. The only real question that I have is, is it okay to keep the whole tank submerged in about 1-2" of water without any movement for the water. I mostly want to make it a Drosera tank and have Capensis and other South African species flourish in it. I've read countless threads on all types of forums saying you need false bottoms and must change the water monthly but after reading the thread above it seems like everything took well to the standing water. Or would it be a better option to have everything in separate trays just on a shelf?
