I haven’t used it personally but I’ve seen experienced people post that they have used it. Should be fine.I got seachem coral dip. Hopefully this will be OK? I don't think I will have time to make it to any stores in the next week or so. Been super busy so just ordered something off of Amazon that would be here in time. I think it was the only choice from what I saw was available for 2 day prime. Ordered it real quick at work so didn't have time to look much.
