The temp reading you see in the picture is 78.8. The chiller kicks on at 79, and drops the water to 77, so it stays in that range. It's hard to say if the corals were doing better at the higher calcium level. It seems like since setting it up, certain corals have just not done well, while others do fine, nothing new since dropping the calcium.
Regarding the PH, I have tested in the morning and afternoon, and it seems to range from 7.8 in the morning, to about 8.4 in the afternoon. Is this shift out of the ordinary?
DT's is a product that I buy at my local pet shop. Its this concentrated green liquid (microalgal feed) for corals. Phyto feast is another one they sell that is close to the same thing (may be more common). Is anyone else feeding with this type of food?
