White tips on sps

[RandalV]

This is definitely STN I think? Here's birdsnest/ blueberry fields. Birdsnest is STN probably, not sure about blueberry.

PC rainbow I believe? not sure, since its only tips.

Ice fire echinata - definitely STN?

Left of birdsnest - STN, the one left seems to be just growth tip? It has looked that way for weeks.

I've been slowly increasing my LED output from 25% to 40% over 3 weeks with the acclimation mode after adding T5s but I brought it back down to ab out 35% just in case I was doing it too fast/ too much. Other thing I can imagine why is because I'm slowly getting off zeovit but I didn't really start that process until after these white tips showed up on a few frags.

I had the same thing happen. I thought I was burning my corals so I turned down the lights and lost some of my prized corals . I bought a Seneye monitor and did my PAR readings. They were at around 100 par . I turned up my lights to 90 % with a 40% acclimation for 30 days . Corals are doing great now . Seneye is a good investment!!

What kind of lighting do you use islandlifereef?

I'm using 1 Hydra 26HD on a reefer 170.

I'm using 1 Hydra 26HD on a reefer 170.

I had a single hydra 52 hd over a 50 gallon cube. Now I have 2-52’s. It’s alarming how many ppl have sps issues with hydras.
