I started adding NO3 and PO4 at that time too, so it's tough to say what helped most. Everything grows faster at higher temps though - such as algae.

87-88F is where corals start dying if the corals are used to being 84 or 85F, but if the corals are used to 78F-ish, then a relatively quick rise to 86F will usually start causing demise. What the corals are used to is the biggest thing, sudden rise is never good. What I've noticed in tanks kept at high temperatures like my old tank is that being so close to the danger zone means the tank is very high energy - high fuel. It's like gasoline VS jet fuel.

Now that you posted this though, that reminded me that I want to turn my tank up to 82F and see how it does. For client tanks, I keep them at 78-79F because lower energy, "lower fuel" tanks are easier to maintain imo.

Mika is 100% right! I was running sps tank with halide at 81 to 82f. Acros were thriving! I had to trim them every 6 weeks; but when it crashed...it crashed hard and fast. Everything thrives in warm temp including evil bacteria and algae.
