question about bio filtration

[dogmajones]

I have a fluval spec 5 , and a HOB 2.5 gallon refugium. I recently found a baby Eunice worm in the largest of my live rock which has been in my tank for 4.5 weeks now. I removed the rock, and replaced it with some dry rock, as seeing and reading of this worm has honestly frightened me from buying more live rock, anyway my question is. The dry rock is a little smaller then the live rock it replaced, and a lot lighter. I was hoping I can make up for the loss of bio filtration by adding a bag of Fluval Biomax to my refugium in the first stage above my bag of Chemipure, does this sound like a acceptable idea?

I personally wouldn't bother, the fluval is probably up to the job of biologically filtering your water by itself.

Before I can confirm for definite, what size is the aquarium in question?

it is 5 gallons, with a 2.5 gallon refugium. The refugium currently has a small live rock, and 3 pounds miracle mud, and chemi pure elite in it's stage one, it is this refugium

Ah right, so you're using the fluval that came supplied with the aquarium. If the fluvals been running on your aquarium since initial setup you'll be fine to run it without adding anything else.

I see you're also using a skimmer so you'll definitely be fine.

no what I planned on buying and adding fluval biomax into my refugium

I do have the original bio media that came in the fluval spec 5's filter sponge. I guess my main question was will the fluval biomax pick up the slack from my lack of live rock in my system.
and no I don't have a skimmer in the system, just the stock sponge filter, and bio media that came with the system, a refugium, with miracle mud and chemi pure elite ( chaeto is being shipped now, will be adding it weds)
