I bought the girls a new 10 aqueon tank because the light went out on our 3 gallon and we were using our back up pump on it because the origional pump went out. I bought a tank kit I now feel as though I spent to much and should have just stuck with our original three gallon and not had a light. any way the pump.filter that came with it is too strong for our betta and may be too strong for the plants. Do i try to baffel this thing (if so how) or should I just try to sell it and re coop some of my cost. and put the old pump/filter back in it. the old pump/filter said its for a 3-5 gallon tank as least If i remember right it did. I don't think it went up to a 10gal. so it might be a little small for the 10 gallon I don't know what to do and I am feeling very frustrated with this hole home school project. any advice
the new pump is an aqueon quiet flow 10
My old pump/filter is a tetra whisper I believe the box said for 5 gallons.
This is fixable, you can put some kind of foam on the output of the filter. If this filter is a hang on the back (HOB) type, you can maybe use foam filter from Aquaclear filters to slow the flow down. Also, search the "Planted HOB Thread" to get some ideas as well.
One way that I use to baffle the flow of HOB filters is to buy a cheap soap dish from the dollar store. They are clear acrylic and come with suction cups to stick on the tank wall beneath the outflow of the HOB. Little drain holes allow some water through and the rest is diverted back up to the surface. Works a peach.
