Acro losing color at top. Light acclimating

[Cbones1979]

Acro is halfway up the tank for week 2. Seems to be losing color at the top.
Here are my numbers

You suggest it may be the light. And you give us your water parameters and don't tell us anything about the light or the PAR (if you know it).

Was on sand at 120 par. Moved up to 220 par mid tank. It’s final resting place will be at 300 par peak. T5 hybrid (2 blue 2 actinic) w 2 30 w leds. Currently just 100 blue leds going...

Here it is w out lights

looks bleaching

Lights out with zero PE. Looks more like it’s unhappy. That up and down Phosphate is my guess. What are the levels at the high curve and how fast did you drop it to where it is? Those graphs are sometimes misleading though.

I think this may be pushing more nutrient side than light or a combination of both. Last time you tested N03 was on 12/20. I would update those test and report back. Could almost guess you have 0 nutrients and then light also plays part.

Each week i take them and I have gha so when it says 0 there are phosphates

I’m going to work on increasing nutrients and light slowly and hope it recovers

My guess would be the low phosphates. If you are using a Hanna ULR, 0.01 is within the margin of error so it could also be zero. My sps start to bleach out if they spend more than a few days at undetectable or close to it, phosphates.

Prob should turn skimmer down. I think my algae scrubber skimmer and chemipure combo is too much

Yea if you have a skimmer I would turn it off completely until your nutrients rise where you want them. Then from there just monitor!

Just a sidenote: your test reading 0 phos is correct; it’s not that it is in the water and just not reading on the test, it’s that the gha is outcompeting your coral for it. As far as your coral is concerned, it is 0 phos.

Agree. I’m feeding them weekly with reef roids but day to day they’re probably short. Rest of corals are thriving as my frogspawn growing new heads daily and zoa’s went from 4-11 heads in a month

Just measured .06 now

Nice! Sounds like you’re ahead of the gha

Not trying to hijack or derail but what software or controller are your parameters from? Says Rt?

Hanna checkers for alk and phos. Api nitrates ph calcium

Worse today
