Top Off/refugium

[The Hawk'ster]

Does any have a refugium in there top off water system?

[Canadian Man]

No because you should be topping off with fresh water:rolleyes:

[rastafarian]

assuming that your top-off water is fresh water and hopefully nutrient free, how would you mix the two and why would you want to?

sorry to sound so skeptical...

[The Hawk'ster]

very stupid question.....:lmao:
