Acans issues

[w8lifts]

My acans keep showing skeleton but has feeding sweepers fully extended. I’m really struggling on what they are needing. I changed my lights to AI blades last month and they started doing this.

Par level at that specific spot 80. Par goes from 40-140 in my tank.

About to check parameters

What are you feeding them?

 

[w8lifts]

Alk 7.5
PH 8.3
PO4 .5
Nitrate 56
Temp 78
Sal 1.028

What are you feeding them?

I broadcast feed every other day with benepets. Tank also on two auto feeders, one is avast dry freeze and the other a mix of small pellets. Tank is also a high nutrient tank with no filter just skimmer.

Your parameters look pretty good for scans they like a bit more dirty water than most laps or sps do.

think your par is a bit low I just checked my kitchen tank that’s mostly torches, candycanes and hammers. It’s also got with 6 acan colonies. The acans are all in the 200-300 range on my apogee 510 meter under halides Maybe raise them up or boost the lights

See that is what I am really conflicted with, so say 50 then others like 200+ par. It gets a tad frustrating.

Mine went from small frags to 6-7 inch colonies under same lighting for whatever that’s worth

Your parameters are way off, specifically your Nitrate, Phosphate and Salinity. Reef tanks should never be above 1.026 max, no doubt that is causing some trouble. Your Phosphate and Nitrate are in the correct 1 to 100 ratio, however Phosphate above 0.2 tends to cause recession in meaty LPS IME.
Work on reducing Salinity slowly over the course of the week. Definitely raise it to higher par, again slowly, and perform a few water changes to adjust P & N.
EDIT: To be clear, Phosphate causes what I call ghost recession. The coral looks happy and healthy but slowly dies away from the edges as yours have done.

Imo phosphate test kits are highly inaccurate so would not bother with any test just feed heavy

now I got one saying my tank is good and another not lol. Hmm k thanks, i will just keep troubleshooting

 

[w8lifts]

I just recalibrated my salinity checker. I’m at 1.026. 35.6

 

[w8lifts]

So I changed the schedule to do a more of a ramp up and ramp down to see how they react to more par (25% more royal blue). I really don’t think it is a phosphate issue, that number hasn’t changed in a very long time. It’s my nitrate that fluctuates the most and why I took out the fleece roller, that thing can bottom me out quickly and found myself chasing #s. Double checked my salinity and it is sitting where it needs to be, I did a slight adjustment to my ATO to bring the salinity a tad down.
