Sump for the tank upgrade has 9 media baskets.... I use clear fx pro right now for carbon and assorted other benefits, as well as aquachar which works like a biomedia and somehow miraculously helps keep my ph a little more stable (i've tested taking it out and watching the meter, it's definitely the aquachar) but that's literally all I have in there other than ats (which I checked on this morning and is really starting to take off!), skimmer, filter pads. I used to have a hefty chunk of live rock in there, but it was pulled out for the pico tank.
Anyone have media they swear by that they think I should check out?
Also, placing the tank order tomorrow!
