Euphilia frog sprawn not coming out

[Rjack305]

I recently installed this new ai prime light plus a protien skimmer. My coral was doing fine for two days now they retracting. Need assitance?

Yikes! What are your parameters?

If the only changes you made were adding the new light and protein skimmer, then they are both likely to be partially to blame. But, the hair algae evident in the photos may be indicative of elevated NO3 and PO4. Test for both, then remediate as necessary. Ideal range is 1 to 100. Example: .003 ppm PO4 / 3.0 ppm NO3

Euphyllias will often respond to photoshock with polyp retraction. I call it "squinting", much like you would walking out into a bright day from a dark room. Try running the Prime a bit lower at first.

Further, it doesn't look like you have a significant bioload, so it's possible the water is too stripped by your new skimmer. Try running it only at night and only for 3-4 hours.

On a tank that size with a small bioload a skimmer could be problematic. I have run my 10 gallon reef without a skimmer for years. I find that it is much too easy to "sterilize" a small system with a skimmer and a lot of chemical media. My tank has always done its best with a little chemipure blue in the filter box and no skimmer. I would recommend running the skimmer sparingly.

Yea i check my levels tommorow. I been running protien skimmer all the time and have chemipure plus another carbon for media. My light levels are 85% for blues and 10% for white. I definately appreciative of you guys responses. I will post my levels once my water gets tested.

I think my nitrates might be way to low
