Water change

[MACHO]

Hey everyone so just thinking through my head today. Going to be doing a 70 gallon water change on my 200 tank barely any if no coral in the tank also going to be removing 3 rocks from my refugium and vacuuming out as well as removing the algae that has built up on the chateo any negative side effects I should be wary of or none that I need to worry about

No, you should be fine

I have a 40 gallon holding tank for water changes that I change 35 gallons in the 180 every 2 weeks. I don't dose anything. My corals are happy. I don't think you would have a problem.

Agreed with above. No worries. That is basically what I do.
