Fluval A1456 First Impressions

I use the APC brand.

I will be using Koral Filter material from now on. Don't restrict air-flow around them as they do get quite warm. The first 3 pics are of my RR tank with sump. You can cap off the ones you don't want to use. I've definitely noticed a difference in my water quality. Of course you will need to let the silicone cure before installing in water. I end up cutting a small 2x3 inch square for each of my media baskets.
