Had a 90 running with 2 aquaclear 110s and a red sea Berlin simmer set up as a hang on. Ran well until i dropped one of the aquaclear when i was cleaning and it broke.
im guessing your tank is not reef ready.you can have someone drill your tank or get a over flow box and add a sump to add a good skimmer and reactors for phos and carbon.als you can put your heaters in and also add a refugium.
Probably not reef ready per se but my corals have been doing well. Hammers doubled size. Sun corals growing, trees splitting, polyops spreading, etc. But i agree probably not optimal setup
I have a 20 gallon long sump $35 and a cpr cs90 overflow box with aqualifter pump $65 and also a mag 7 pump $40 that will work great for your tank had it on my tank and did the job great with no problems and little to no maintenance. plz let me know tyvm in advance and gl
