Alright guys, sorry if there's a post already concerning this but I'm lazy/drunk so I don't feel like going through 50+ pages of posts. I'm just wondering if anyone has turned a wet/dry filter into a capable water filtration system for a saltwater tank. My girls father has one in storage that he isn't, nor will he, ever going to use again that I can possibly use, pending dimensions. Was just wondering if I can use it to add some water volume and what not. I've been looking around online but I haven't seen anyone using one for a saltwater tank. Except one forum where a guy threw some LR rubble in where the bio balls were. Anything wrong with this? I'd really like to see this happen cuz I'm tired of looking at my fans, skimmer and heater.
