Mine is a Fowlr set up, So can i just top up with aged water?

Hi bro, topping up is always using freshwater(preferably distilled or RO/DI) or u can add aged tap water treated with seachem prime.

As for WC, it depends on the bioloads and the efficiency of ur filtration system. Hope it helps! Happy reefing! Cheers!
