I understand this statement if tank is young and you do not have a bunch of corals yet. So agree with you Joe "love the nameAnd I've never checked KH not something I really worry about you know?
"However you should watch ALK when keeping corals.
Personal experience in my 38 Nuvo (at this time is heavy SPS)
Early on I was testing for ALK and thought #'s were good but corals were not looking that great until I would do WC of 10gal then things would pick back up. Had LFS double check test and low an behold ALK was way off. API test was running 8 range and Red Sea at LFS was 6. PSST Invest in other test kits besides API (Hannah, Salifert, Red Sea)
The coral in particular was a cyphastrea that would go almost white. Month and half of 10gl WC every other week and back to aqua. Took me a bit to have LFS double check my #'s.
I invested in all new red sea test kits and hanna for the alk.
EDIT I should add that I utilize kalk and weekly 5gal WC to keep my #'s stable. I you are new to hobby kalk can be a beast and not something you just jump into and most likely would not need for a good 6 months or so(probably, maybe, depending on how big your wallet and tank are)
Good thread Joe
