We did not do an acid bath simply because of the type of rock we were using. It simply didn't seem like overall it would really ever completely accomplish what we were looking for by burning it off essentially. We have not had a major issues with phosphates at this point. We are running a BRS GFO and carbon reactor and it was placed when the tank was established so maybe that has helped to keep phosphates minimal. We have only had very small algae cycles at this point. The first wave of diatoms started to show its face and didn't cover the rocks even and maybe a quarter of the sand. We added only 5 Astraea snails, 5 cerinth snails, 10 hermits, and an urchin at the first sign it was going to start. The Astraea snails were the real champs in that battle FYI. I think once the clean up crew were in we had four days of my wife complaining about algae being visible. A little later started another small wave which because the CUC is already in there has been minimal at this point.
None of them really wanted to mess with the back wall though and we added copepods because of wanting to add a Copperband Butterfly mid February and wanted to have them available. Well, the secondary benefit to those being added is the entire back, overflow, and front glass have been cleaned without any help from any other members in the tank. I had no intention of the copepods making it so I don't have to clean the glass but well mine have left the sides sparkly clean!
I am far from an expert, but this is how we approached it and it has been working thus far. I know there will be algae as we move forward but up to this point the algae waves have been minimal and seem to leave as quick as they had come. The other thing is we have been super slow to add bioload which has maybe helped as well because the system has time to build up rather than play catch up.
