29 gallon bio cube question

[nport19]

I have had this system up and running for 2 years now. It has a canister filter along with the stock one and a portion skimmer. I keep the salinity around 1.023-1.026 the temp I have always had a problem with sits at 80-84 degrees. I have taken the hood off my bio cube to make room for the skimmer and a new light. For all those two years I was running LED lights and wasn't seeing much coral growth. So I decided to switch to a T5 aquatic life light. They have been on the tank for 5 weeks now with a mesh screen to dim the light intensity down. I was wondering when is a good time to remove that so full light can reach the corals. Another thing does anyone else have a problem with some corals acting all sad when all the others are fine?

Your salinity and temperature shouldn't fluctuate that much. Should only stay between 1.025 and 1.026. Temperature should stay within +/-2 degrees. Temp should also be around the 77-78 deg range. Testing Alk, Ca, and phosphates should give you better information.
