Currently in my 2.5gallon I have a TOM's internal, and while it is small, it is difficult to place it correctly with my scape, shrimp can get behind it and sometimes not get out, its just not working out for me...I want to swap to a sponge but have a few questions.
1 - How do you clean it and not lose your bio helpers? I wouldn't gain anything space wise if I had to use a double sponge filter so that is kind of out.
2 - How do I introduce the new filter and not ruin the cycle of my tank? my thought was I would have to run both for a while? It just made me think it would take a while because the bio load is small, just 6 very nice painted fire reds, and 6 very nice SS crystal reds and some plants/moss/cholla wood scape.
I plan on going with a small powerhead http://www.fosterandsmithaquatics.com/product/prod_display.cfm?c=3578+4586+22583&pcatid=22583
180 180 gph 4 1-1/4" x 3-1/4" x 2-3/8" high adjustable rate, and then attach that to the sponge filter to keep everything in the tank, my only reason for this was because I have yet to find someone say they have an airpump that is quiet, and this tank is on my night stand...any suggestions?
I am about to setup a Fluval EBI to take place of this tank, I plan on using the same sponge in it, so as to only have to do one full cycle, I will scape the ebi, and let it sit unfilled until I "seed" this sponge in the 2.5, and then move it over and let it mini cycle, and add the substrate from the 2.5 to the ebi...same fluval shrimp stratum, which should cut down cycle time alot
I'm open to all suggestions, my goal is small and unobtrusive, and most of all quiet
