Sps acropora bleaching from 5 silly mistakes.

The worst thing is I have made all these mistakes before.

This is my poor sps from five mistakes in a row, one of several sps that dropped most of its algae clades from my silly mistakes.

1.Carrying out an experiment in the pre filter of the NWMS and having an enormous amount of dead tissue in the system and not noticing for several days.

2.Doing a massive trim of my algae part of the NWMS for a friends system to seed it with the algae I use.

3.Letting the salinity drop to 1.021 due to filter wool cleaning.

4.Fogetting to switch back on the chiller.

5.Adding a toxic life form with out flushing its toxins.

All these I did in a span of two days and five of my oldest sps started expelling their algae and I didn’t do anything to the tank for three days so I didn’t notice this happening until they had lost a great deal of the algae they prefer.

So I did my first water change in 13 months, I was hoping for some years before the first water change, but I screwed that up.

The pics are of the corals ordeal.

The beginning of the reaction.

Well into recovery.


Mostly healed.
