From fresh to salt..

Ya the curve was sharp a few times, quarantine tank etc...lack of.

I do use RO/DI water. Again sump will come, I have found some online calculators for sump capacities and what is needed for back flow when power goes off, matching drain size to return pump capacity etc. Will leave that for when the 77 becomes the "well done all I can do with this one" tank and start looking at a "real" tank as far as size in concerned.

The 77 is going to be a FOWLR tank so water quality won't be a huge issue.
