SPS bleaching HELP!

Morgosverlo123 · May 15, 2016

I have had my 55g cube set up for a little under a year and all has been good until I noticed my acro began bleaching from the bottom and noticing some of the polyps near the base that protrude look empty. The tips look fine and alive. It is a mixed tank and all my LPS are great. I have been using Red Sea salt and Fusion 2-part for supplements that are dosed with a bubble magus. For lighting I have AI SOL and a eBay Mars Aqua 165w LED. Only thing I've changed is the salt mix. Switched to Tropic Marine . A couple days ago I had my fingers in a back chamber and could feel a tingle under my nails(I bite). Felt this before in a planted tank and new I had a short in one device. My first removal was a cheap heater. I removed and current was gone. That was the day my pagoda was spitting black stringy stuff. I could tell something was wrong. That's fixed. If that was the problem will everything recover? Or is it something else?

Possibly, what are your parameters and are they stable?

No joke, just feed more planktonic/dusty food.
They're going through some sort of stress, they need more POWA!

I purposely buy dying corals from the store in the 5$ bin. I feed reef energy hourly, dosage x 2 per 24 hours. But I swear by the addition of larger quantities of nutricell. Encapsulated ~80 micron food. Takes >48 hours to decompose. I've even fed 1/2 a teaspoon before with amazing success, and the spoon that comes with it is about 1ml of food? Like the size of the red spoon in salifert test kits.

Think of yourself covered in slime, and then you stand in front of a fan that's blowing flour all over you. That's how it works, and it works wonders.

On a side note, in the red sea reef care program, they equate necrosis from the base up, to lack of nutrients.

Really tough to say what the issue may be without any test results. How are your nitrates and phosphates? How much water flow do you have in the display tank?

Try feeding homemade chum mixed with oyster feast and rotifiers. I blend a variety of seafood and add those two in large quantities along with selcon and feed twice per day. Blend it well. I was also running very low nutrients and didn't want to dose to bring them up. This food mixture keeps my N03 around 6 and P04 around .02.

I make it and pack into zip locks and freeze. Lasts me around. 3 months.
