mixed saltwater

[Reefermike]

I have about 30 gallons of saltwater that has been mixed for about 6 weeks has always had a pump circulating in it . Use it or throw it out, wanted to change out 30 gallons today and another 30 in couple days.

I would use it. But others say the chemistry will be off. Maybe test cal, ch, and mag. If there good use it

If it's for fish only, it should be okay as long as salinity and ph are fine. If it's for corals, then those parameters will make a difference.

i really am not worried about Ca and what not as i am going to do another every 3 days until i get it back to where it was before i got off track. I should say there is no algae in the tank it self but bubble algae in the overflow.
