Best filter for 40 Gallon Breeder

[dustin.j.purdy]

Right now I have a Whisper 20-40 filter, undergravel filter, and a coralife super skimmer 65. i am wondering if my filtration system could be part of the problem to my brown and green algea overgrowth. Any suggestions on a filtration upgrade?

I would say that your undergravel filter is probably your problem. Undergravel filters arent the best thing for a reef or FO tank they tend to make high nitrates and other bad problems. A skimmer in a sump is to me the best way of filtration also with some cheto to.

I think the UGF and power filter are the main reason for your algae bloom. I suggest LS and LR as the basis of your filtration. When coupled your skimmer and you should be good to go.

so you think i should take out the ugf filter, and the hang on filter, and just run the protien skimmer and my live rock. also i have a crushed coral bed do you think i should switch it to ls.

Dustin, I would switch out the crushed coral for aragonite sand. The CC traps detritus and the sand won't. You can buy dry sand and your LR will quickly seed it. You can use the HOB filter for flow or to run carbon in but I would not use the bio-wheel or whatever your has.

that wont wreck my biological filter if i change out my bed will it.

You have LR in the tank, right?

i have 48lbs of live rock

The LR should sustain your bio filter. You could change the CC for sand half at a time.
