Uses for canister filter??

[ITeach2Wheels]

Ok, here's my problem...
I bought an established system for the rock...very nice stuff lots of big pieces.

I am starting a 30g with a 20g sump/fuge. The tank has been running for 6 weeks with the rock in it for a month or so. Judging by my off the charts PO, the people I bought the tank from, used well water not RO/DI. I use only RO/DI water but my PO tests are off the charts.

The canister filter off the system was also included in the sale My question is, can I use it to make a DIY Phosban reactor and maybe be able to run carbon as well?

There is nothing in the tank right now except for a ball of cheato and gravel from the rock system in the fuge to start a DSB.

I do have some hair algae growth, but no real light yet so nothing serious.

What do you all think?

I have a Magnum that I mostly use for water polishing. I have an insert to run carbon and I suppose it would work for phosban as well. I don't think you want to necessarily mix GFO and carbon as they are exhausted at different rates.

It's not the most eficient means of running GFO, since the media doesn't get fluidized, and the flow rate is definitely not optimal, you certainly CAN use it in the canister, and it's better tan not running it IMO. I used to use a canister for running carbon, but switched to a second TLF phosban reactor since it's much easier to maintain, and takes up far less room than that stupid canister.
