Hello! I just set up a 6.6 gallon aquarium with 2 inches of dirt and a thin layer of gravel on top as substrate. I am planning on keeping 2 african dwarf frogs, malaysian trumpet snails, California blackworms, and trapdoor snails in that tank. I already have the animals I wanted in a QT. Even though I did about 6 water changes, the water is still a very dark brown, almost black. I can barely see anything in the water. The filter doesn't seems to be doing much to remove whatever's dying the water. (It is a Fluval Chi tank) I am leaving for vacation after 1 week and I am bringing my grandmother back with me to check out my house, so I don't want to the tank to look terrible at that time. Is there anyway to make the water clear again? I don't mind a bit of tannin from the soil, but I do mind not being able to see anything and basicly having a tub of mud. I used NatureGro Potting Soil so it have no chemical fert and such. It is all "aged pine bark", moss, "forest compost", sand, and some perlite that float out. Please help!
