Does anyone have any experience with "Renew" media from Seachem?
It claims to have similar properties to activated carbon but will not agressively scrub away the chemicals needed in a planted tank.
For those who are not familar, with the setup I have with Emperor powerfilters, there's a pair of slots where you'd normally slide pre-fab carbon filter media inserts (mesh bag, with carbon in it).. then there are a pair of empty media baskets behind that. The question is, when I rip out the pre-fab things, what do I do to replace them.
I bought some 100micron mesh stuff that's supposed to be good for doing mechanical filtration, and I chopped up a bunch of fluval foam and stuck it in the basket to provide some more mechanical and some surface area for nitrifying bacteria. Keep in mind that this unit has 2 big bio-wheels.
With my 75g tank I have two of these emperor setups, which do 800g/hr...
Could this level of surface agitation/water flow be causing me problems as well?
