I have ten running at the moment. I do 50% water changes on the 125 and planted tanks biweekly. All other tanks get weekly changes of 50%-75%.
125g- SA/CA (FX5)
75g- 1 JK flowerhorn (avatar pic) (FX5)
75g- CA/SA (FX5)
54g- planted community (405)
40g- planted community (405)
40g- CA/SA growout (405)
25g- Kamfa FH growout (405)
16g- EBJD growout (AC70)
Eclipse 12g- Red Texas growout
Aquapod 12g- mini reef (standard filtration + koralia nano, powersweep)
The plant tanks and mini reef get RO/DI water. All others get water from the faucet. I recognize that I do not have space for all of my fish to reach adult size, and will bring them back to my lfs (I am the manager) as they begin to outgrow my tanks or when I am no longer interested in them. The 125 is in my classroom (I teach 2nd graders). All other tanks are in my 2-bedroom condo.
