My GSP is losing it's colour

[mucky1957]

hi

I have a lot of pieces of gsp in my tank but some are beginning to show signs of going pale..any thought's please. I have them dotted all over the tank..top/middle/on the sand and the ones looking sad are in various positions. It's not the flow..it's not any fish/invertibrates picking at them or the lighting.
I have a 4' 240lt tank with a lot of coral and fish ( all doing well except the pieces of gsp ). Levels are fine with nitrate constant at 2-5 and phosphate slightly high at 0.1.

Is there some form of food I can use to bring it back or might it be a goner ?? It's been like this for a few weeks now.

Thanks

Lights could be one the reason...

no..the lighting hasn't changed in 5yrs...been using the same LED's and the same timings. This has only just started to happen and only to 3 or 4 pieces out of the 12 that I have.

Will it be possible to change the location for the specimens.

unfortunately no..the gsp has fused to the surrounding rock and its all piled one on top of the other..

Check your nitrates and phosphates, they should be just barely detectable and not zero. I had the same problem and starting dosing stump remover, hope that helps!

I found you can literally peel off GSP from rocks and glass panel

nitrates are between 2 - 5..always have been
phosphate is at about 0.1...a little high but again it is always the same
I have tried to pull th gsp off the rocks but it seems to shread. I am trying something called VITAMARIN-C...its a vitamin suppliment and it 'seems' to be working..only using a small amount each week..but we shall see.

thanks for the replies.

I started mixing my own salt about a year ago (red sea pro) and stopped using Kent marine a+b nano in combo with pre mixed LFS saltwater. All the corals started fading then my GSP closed up. Randomly I found the Kent marine stuff in the back of my closet and decided to give it a go. The next day the GSP were open and over a week they regained their color. I have no idea if it’s pH or trace elements. I was dosing BRS 2 part with Mg the entire time. Nitrates. 0.5 phos 0. Hope that anecdote helps

Hey Mucky, did you ever managed to return color to your GSP?
