Help with some issues

[fishguy597]

So three days ago I did a 20 gallon waterchange with the probiotic salt. I started using the probio S, np pro,Coral A, and Coral B the same night. Then then the next night I added pro bio s, np pro, and Coral b. Everything was fine at this point. The pe is fantastic so I started with everything else. Last night I added the np pro,probio s, coral a , coral b, coral e, and Coral v. The problem I'm having now is my Hawkins echinata is starting to have the skin peal off it. I have another coral that the base is getting very light on. All other corals look great.

The tank is 200 gal with another 40 in the sump . I figure the water volume to be around 180 gal with the rocks. I have only been using 3 drops per supplement. The tank has been running for 3 years. Yesterday everything was fine and once my lights came on today I noticed the 2 corals having the issues.

I'm running 4 radio Gen 2's and 2 54 watt coral plus t5's. A skim skimmer sm 201 ( cleaned 2 weeks ago and cup filling up every other day with dark skimate). I'm running a calcium rear with aragonite,coral skeleton's, and bright well neo mag. A gyre 150 and 2 mp 40's. I'm also running a 2 little fishes phosban reactor with 1.5 cups of brs gfo. Other than cleaning the skimmer 2 weeks ago and changing the gfo at the same time nothing has changed.

Alk is 8 dkh
No3 is 5
Salinity 1.026

What do I need to do? I'm not going to dose anything today.

Should I start trimming this coral back to save it? It's about the size of my hand.

Can We see photos of those corals?

Here is the hawkins

Here is a small chunk I kept. I discarded the rest of the clippings.

This pic does no justice since I do not have a camera filter. The base was a nice dark green and now it's getting white.

This morning I dosed pro bio s, np pro, and Coral b. I reduced it to 2 drops each. Tonight would be the night to dose coral a,e,and v. Should I dose them at the reduced drops of 2? I'm only guessing from what I have read in other posts. I'm also following the directions of starting out with half the dose.

 

[Aquaforest]

Half dose is very important because corals should knowing new supplements.
Did You see that skin peal off before?

 

[fishguy597]

It differently wasn't pealing before. Also the base of the red coral was green before starting. I checked all corals before starting the program. I've reduced to 2 drops to see what happens.I reduced the coralE to one drop. Is this the right move?

 

[fishguy597]

By the way figuring at 180 gal 3 drops is a little less than 1/2 dose.

Over the last few days my skimmer cup has been filling up with some really dark skimate. Today is the second day in a row it was filled with in 24 hours. I have the skimmer set towards the dry side. My corals are a little lighter than normal. But over all very good.

When I started the program 6 days ago, I checked nitrates and they were at 5. Now today I'm at 1. I tested it 4 times with 2 different salient kits. Is this even possible?

I started out at 3 drops and have since reduced to 2 on everything except coral E(1drop). If this is a true nitrate reading ( wich I think it is) should I back off on the np pro and pro bioS? Maybe a drop a day or 2 every other day?

I usually feed my tankeverytime I walk past it with pellets or frozen food. I have 1 purple tang, 3 yellow tangs, 1 tomini tang, Solaris wrasse, melears wrass, 2 clowns, and another small fish that name isnt coming to me.

The encrusted parts of the corals that were turning white have started to gain some color and the polyps are coming out again. My water is clearer than its ever been. The rest of my coral have excellent polyp extension. I'm starting to notice color changes that are fantastic.

I'm going to keep an eye on the nitrates. Am I going to have to dose nitrate to supplement what I'm loosing?

Check NO3 one more time after few days.
Probiotics is working so it's possible
