Review on Enhance Your Aquarium's Filtration with Fluval Biomax Filter Media by Rebecca Vattikuti

Just what I needed, I got the sponges from a Marineland Emperor 400 on my 30 gallon reef tank. The tanks have been up for a year now and the dry live rock I've used is starting to grow well, but I haven't decided what to do with it yet. Instead of removing the extra flow the hob added, I just put them in between the chemical canisters and the bio wheels. A box filled most of the page. Will update if I notice a charge, I don't think I will, this is bio media not showing much. Well, swap it out with one of the 55s we eventually have and probably dump those rings in that swamp and then upgrade.
