ok....I may not be too clear. I DO NOT plan to keep 20 fish in this 48G
display tank. However I do want to MAXIMIZE the amount of fish I can without
allowing for more waste product disrupting the water quality. Hence the sump
to add more water volume to dilute the waste. I basically want to add 2-3
more fish (clown, flame hawkfish & a yellow tang).
I currently have:
-4 Damsels
-1 Blue Tang
-1 Fridmani Pseudochromis
-1 Blue Chromis
As for the wet/dry/canister, you are suggesting I remove them and only leave
the LR,DSB and Protein skimmer?
Thanks again for your help.
