Replacing the check valve would be pretty easy. Its in a good spot.
Also, Ive picked up the parts to run an absolute emergency drain into an empty reservoir that I can hook up. After I get that draining into, say a 10G bucket or tub, I would be very very confident my tank would be almost flood proof 100%.
Anyways, I went to the store today and was looking at small frags in the sps tank and just got wondering - what special care exactly do SPS corals need?
Im going to have a 165G tank with three 250W HQI Metal Hallides and four 96W Blue Actinics. My water will be completely RODI. Using reef crystals for salt.
What else do they need? Im guessing some kind of dosing? What other care? Id love to have some.
