Safe to turn filter off??
Iím new, the tank is used but new to me, 29g, cycled, planted. With water samples and the blessing of the LPS I picked up a black molly, a silver molly, and two platties today. The tank has an over-the-tank filter of unknown capacity that creates a pretty strong current inside the tank. Iíve planted ludwigia repens, java fern, java moss, dwarf baby tears, an anubias nana petite, and some moneywort. The black is active constantly and the platties go back and forth from active to relatively still, but the silver, if the filter is running, seems to only want to find a spot with low current and hang out. Iíve tested to see what happens with the filter off and he becomes much more active around the tank, even stopping occasionally to eat some algae. Do I have enough plants to leave the filter off and not worry about oxygen for 4 little fish? Would this create problems with ammonia? If I need to run the filter, can I run it on my light timer (5 on, 5 off, 5 on, 9 off overnight)? Or should I not be concerned about the silver molly and just let the filter run 24/7...?
