Setting up New Discus Tank....question
hi peeps... getting back into the hobby! considering a 120gal tall.....60x18x25 or a 90gal 48x18x24 for discus and i used to use undergravel filters but the preferred nowadays is a wet-dry sump below the tank with trickle and room for heater... should i buy a 'reef ready' with pre-drilled holes and built in overflow? dont really like the idea of holes in the tank but seems cleaner and safer during power outage... anyone have a pic? best way to go?
also...what if the return pump flows at a different rate than the incoming water from tank syphon? dumb question? thanks in advance!
