Can anybody tell me why is it that when my tank get really dirty and I scrub the glass off and blow off the rocks my acro frags die every single time. The frags will look great the entire time until I clean the tank... This very turbid water the cleaning creates clearly ticks them off to the point of death but why???

Very strange. What would happen if you cleaned the glass everyday with little dirt coming off the glass each time?

Its very strange, everything is great till i scrub off all nasty algae and coraline algae. All the corals close up everytime but my acros just go up in smoke...

weird is right, i have dropped acros in the sand and they are fine still. What are you using to clean the glass and blow off the rocks? Could also be lotion or some other residue on your hands but it is still super weird

You might need to test your water before and after your cleaning routine. Particular nitrates and phosphates. If that doesn't show anything, it could be a bacterial thing. As you clean, its kicking up bacteria, which then settles on the coral. It definitely sounds like something is getting released as you do this.

A while back, I had let one of my smaller tanks (just LPS and fish) get rather mucky. The usual algae, detritus, coralline, but also some chrysophyte like stuff that looks like dinos but it is not. Sometimes called "golden algae".

Anyway, I finally got to work with a scraper cleaning the sides and bottom of a 40 breeder. I turned off the circulation so I could vacuum out all the crude into a sock in the sump. The fish were hiding. LPS pretty annoyed. This took about 20-30 minutes or so and then turned circulation back on.

Come to realize then that my fish weren't hiding. They were all dead bar one small tomini tang.

Somehow, stirring up all that muck either:
a) Consumed all the oxygen very quickly
b) Released some kind of serious toxin
c) Somehow that level of turbidity suffocated the fish.
d) All above or other

In a "normal" state, those fish could last hours without circulation.

It is an imperfect comparable to your situation, but it has changed my risk assessment protocol for sure.
