What is causing this?

Water is fine and everything else seems to be doing fine also.

Death from below and in the shadows is quite common with small-puck LEDs. This is why a good portion of people with SPS add T5s.

Will the whole thing eventually die?

It could, but not always. Sometimes, it just has death from below and live tissue on the top near the lights. You see this a lot with Kessil tanks too.

Check for pests too. I know that nobody thinks that they have any, but look closely and look twice.

How old are they?

How old are they?

No idea. I got them about a year ago. Guy claims he shut his tank down over five years ago so they sat a lot. I have 6 of them over a 7 foot tank

Well they definitely lose power over time from usage. I have 2 hydra 52 HD’s that were purchased a year apart and the older has about 5-10% less power than the newer one. I think you should find out what par they are producing.

I actually have one coming my way once it gets returned to BRS

Could high nitrates be causing this. Seems to be creeping up on me.
