Tank Covers

[kramleigh]

Hi,

I am converting a fw tank to sw. Since I am unsure if the hood and cabinet is reef safe - hood's hinges are slightly rusty, I was thinking of putting pvc covers over both tank and sump. I have read on the forum before that this isn't ideal for good gas exchange. Could I put an airstone in the first chamber of my sump to improve this?

Thanks, K :rollface:

Airstones make a big mess in saltwater systems. I wouldn't do that. I'd ditch a tight-fitting hood or open up some ventilation in it.
