I was reading another thread on the CPR Bak Pak 2 and some said they have removed the bio bale and let the live rock do all the bio filtration.
I have a CPR Bak Pak 2 and a 350 Mag canister filter that I use now with carbon along with two 660 powerheads with sponges. I rinse the sponges and change the canister regularly, but have never done anything to the biobale.
I classify my 75 gal
tank as FOWLR
, but I am not sure that is correct. I started with base rock (lace, Coral and tufa) and coral skeletons along with some of the marineland fake corals(removed the plants) and then seeded it with about 20# of live rock(given to me) about a year ago. No Idea on total amount of base rock guess 70-90# (The tank is full).
According to what I have read all rock eventually become live rock to some degree over time as it hosts bacteria and other life. The question I have is when do I know this has happened and should I no longer use the biobale. All the rock has visible coloration on it from the original bleached appearance to the multi colored patterns of algea and other stuff (not much coraline as I do not have the lighting less 1.5 WPG
I do get trace amounts of nitrates occassionally, but all is well in my tank(use RO
and regular filter maintenance with exception of biobale). Should I rinse/remove boibale?
I am very happy with the setup and inhabitants (see profile) and have no desire to go reef (add live corals) as I cannot justify the lighting expense or have time for maintenance of corals.
I was considering dumping the 350 canister and adding a 2nd CPR bak pak 2 (good deal at LFS
). Should I use bio bale? Admittedly, my tank is heavily stocked (PC
), or is this a case of leave well enough alone. It has been months since I have experienced any mysterious death or dissaperance.
Sorry for the long post and TIA
for any suggestions.
