Coraline bleaching...

[Riotfishdude]

hmm,i pick up a few buckets of IO salt when i'm at my old wholesalers depot,and if out i pick up a few buckets of Tropic marin (the 2 brands he carries and i would use),it takes me a long time to go thru these buckets with just my 130g FOWLR,after months of IO,i have a couple buckets of TM to use,did a 20g water change and also did some moving around of my rockwork (225 pounds) and powerhead placement,now i have some bleaching on the top layers of the rockwork,usually all of my rock is coraline crusted (even with 4 urchins)....salt change the cause?,moving around the rocks?,any thoughts?....Riot....

If they were moved into areas of higher light than before, they will frequently bleach.

Was the top of your rockwork exposed for a long amount of time?

no worries Erik,devil is correct,it is pieces that i moved from lower and more hidden areas of my tank to the top,wasnt thinking when i posted,was more curious to whether the change of salts could do this then the obvious reason.... :? ....Riot.....

The growth of my coralline makes a reverse bell shaped curve under my MH light on the back glass. It grows better the farther away from the light it gets.

Sounds like a lighting situation more than anything. Riotfish- check your personal emails for one I sent you last week regarding local lfs's.

I recently switched from using Instant Ocean salt to Tropic Marin in my 500 gallon reserve because I herd It was "The Best" from someone I respect as a reef keeper. I have not had a burst of coralline growth after water changes like before.

This maybe a combination of things in your tank. Don’t rule out the salt as part of the solution even if it is a smaller part compared to the lighting issue.
