I'm in two minds at the min about changing my set up from freshwater to marine, do they work in the same way, can I still use my filter or do I have to get a sump? All the information that people have on marine is more than welcome
Dont know a lot, but I'm sure you will need a sump. I take it you've done your research on salinity levels, the use of live rock etc? I hope a more experienced member can help!
