Are you doing Frontosa again or trying something different?
Most likely, if I end up with a big enough tank.Would you keep frontosa again?
I would am fx4 would do good, fx6 if you are willing idkI’m told it has filters to support a 200 gallon tank.
I always over filtered my tanks, back in the day. I have ordered a AC110, won’t be installed immediately.
Back in the day I ran 2 of those and an fx5, on a 180.
any suggestions on a FX filter for a 75?
