Hi everyone, I am new to reef tanks, and I need advice. I have a 90 gal. and would like to know what would be the best way to filter it. I will have both live sand and live rock, and plan on corals and fish. The 2 filters I have now are a Penguin 200 and a 350 Bio wheels, combined will be good for 125 gallons according to the package rating. Thought about a refugium but not sure I want to drill the tank or have a 2nd tank unless i can keep it to a minimum size. Any advice and comments on the filters or any other components would be helpfull, thanks in advance. :)

hi and welcome. a drilled tank is the best way to go . if you can afford it.your filters will be fine for now but look in to skimmers if you want coral.also a good idea for fish. they will make your tank look sweet.+ add oxegen.. refugiums are a pain for beginners .
swp

skimmers will help alot. they will help alot on free floating diotoms and any acsesive nutrients.. did you start your tank yet or just planing it out ?

saltycrab, until you are ready read the the forum ther is alot of good info here. if you have any more questions post them.

i would use ro water its safer. i dont like adding chems to tap water.
