how long have you gone without a waterchange?

I understatement But FOWLR so no corals is it then also possible not adding trace elements

I am gong on a couple years+ and dose what the tank needs including strontium chloride. You really need to know how to dose and test if you want to go more then a couple months without changing water if only dosing the basics in a reef system due to the elements getting used up

I'm over a year currently on my mantis tanks. I still try to do monthly wc's on my reef for trace elements ect.
