The successful SPS tank

I have no substrate and tons of flow. Its a 90 gallon tank with a Jebao WP-40 on one end, an RW20 on the other end, and a RW-15 on the back pointed down to move detritus off the bottom from behind the rock work.
I am also running biopellets, carbon and skimming heavy.

do you test your water?


colors by its self are almost always lighting or nutrient related

growth would be more towards supplements and flow

Not often. Nitrates have been negligible and phosphates zero according to my Hanna tester. Sometimes I have my doubts with the accuracy of the Hanna, however I do not have any issues with algae so I assume phosphates are in check.

Then it's your lighting. Get a PAR meter and check out what your acros are getting...
