I am not a DIY person.Which ready made sump filters does anyone recommend? I need a very silent one for a 90 gal acrylic tank that I am thinking of buying.
The "very silent" is questionable though because that is really determined by the pump and flow rate. Granted some sumps are quieter than others by virtue of lack of trickling and moving parts.
I would just go with a canister filter for your 90g tank. Wet/dry filters cant be silent, as there is a running pump and water spraying over bio-media.
