Actually, my tank is a 10g with a divider at the back for filtration. So i want to fill the back part full with live rocks and an overhead tray with more lr, would that be alright? Thank you
The Live Rock in the filter will cause the same problems as biofoam, if its not watched it will collect debre and can possibly cause you Nitrate issues. With a 10g tank, you just need to do weekly water changes to keep your water prestine.
I run filter floss, chemi-pure, and purigen (in that order) in my Biocube 14. I'd recommend that or at least some GFO and carbon. If you do the filter floss, change it when you do your water change.
