Raising specific gravity

beatle · 03/13/2007, 09:24 AM

This is probably a very trivial question, but I'd like to raise the specific gravity in my tank. It is currently at 1.023 - 1.024 (measured with refractometer) and I'd like to kick it to 1.025 - 1.026 to help my corals. I have an ATO, and I've considered adding a bit of salt to it to allow this to happen gradually instead of mixing "high test" water when I do my weekly water change. I have a 90g display and 30g sump, FWIW. If making my ATO a bit salty would be best, to what SG should I bring my ATO to?

I would just do it with your ATO, especially since you're really not even that low (you are...but not that bad). I'd mix it to 1.026 in your top off thing. I'd say it should be good in a few days.
