Hi guys, Can someone help me out? I have been looking around for a thread someone (I think Lucy) posted recently about a quick setup for a Q tank. I am not sure, but I think it had a sponge filter and was really inexpensive. I can't find it. :;fru I don't currently have a Q tank setup, but Jaysee convinced me that I need one for when I get my neon tetras. My requirements are 1) it has to be small, no more than 3-5 gallons. I know 10 is preferred but I am willing to do daily water changes if I need to. 2) I cannot put another filter on my 30g. 3) I would prefer not to buy another air pump unless I really need to. 4) It can't be glass. Even my 30 is acrylic. Here are a few questions: 1) Would a small rubbermaid container work, with holes drilled into the lid? or a kritter keeper? 2) Do I need to buy an air pump and airstone, or will the agitation from a filter be sufficient? 3) What is the least expensive type of filter I could use? An internal? 4) I know I need to buy a heater, which is no problem. Will a heater be okay on a rubbermaid, or will it melt the plastic? 5) Is bare-bottom okay, with a couple of plants floating around? I don't have flower pots, but I could stick a teacup in there for a hiding spot (sound familiar? 6) Recently there has been talk of using a product like Cycle in a Q tank, since you only have it up temporarily and don't have to be concerned with a permanent bacteria colony. If I use this, does anyone see any problems or issues? 7) Would it be better to buy a 3 or 5 gallon kit? As always, much thanks to all of you for your advice.
