I replaced the grate over this middle section and took the filter cartridge that's supposed to go in the right section and laid it on top so the water flows from the right over the cartridge into the middle section. Once I feel I can't clean this cartridge anymore, I'm going to get a bag of activated charcoal and put it on top of the floss. But, you can use the one that came with the tank for now. So, now your tank is not a wet/dry system anymore, it's more like a sump. Some people, also, put live rock rubble in instead of the bioballs, but I decided on my mixture after a lot of research and advice from my lfs that's been in business for over 20 years. They, also, turned me on to Seachem's Reef Salt. That has been working out great! I've not had to use any additives as my water readings have been spot on. Anyway, that's just my suggestion. The other thing is, with this type of filtration setup, I keep my tank about an inch and 1/2 over the maximum line. This prevents any micro bubbles. I've just been up and running for 2 mos., but like I said, it's working great for me. Oh yeah, and the noisiest thing about mine is the fans, which aren't too bad. Good luck!
Hey reefer I have a couple of questions for you reguarding your set up if you dont mind... First, when you said a bag of seachems purigen what type of bag and how much did you use in it? I not liking the bio balls at all in my tank, I think they hold too much bacteria. Also there is another grate below the bioballs in the middle chamber that can be removed.. I take mine out every now and then and suck out all the crap that accumulates in there.. Even with filter floss i get alot of build up under there. Did you take yours out or leave it in? Thanks for any help..
