First question:
Randy, how do you feel about anaerobic sulfur denitrification? After researching it I see that the effluent will have a lower ph than the display. I see this can be compensated by using crushed coral. The design I have seen commercially stack the suffer media, then a layer of crushed coral above it, and have a recirculating pump constantly moving water through the layers. How effective would this be to raise PH? Would it be more effective to have a seperate chamber for the crushed coral that only the effluent goes through vs recirculating while the suffer media continues to recirculate? And is there any drawbacks to a suffer denitrification system you can think of? Excess suffer buildup or unwanted elements introduced to the display?
Second question (not related):
I have a 65g SPS dominated tank. I dose esv two part. I have a couple large colonies and about 30 or so frags. Growth has been good, but the tank uses little alk. I dose 8ml of each part daily to maintain 8dkh, 420ca. I see people with similar setups to mine that have to dose much larger amounts of two part to maintain. Should I be questioning my low consumption? It should be noted I do a 15g water change bi-weekly.
Thank you!
