Hi folks. New member had had a marine tank for a year now. Can any of you advise if this can be hooked up to an external filter I do not have a sump and battling high nitrates 25ppm so would like these lower.
What sort of flow rate do we have going through these or does it matter?
Yes you could tee a 12mm line off the return line and use a ball valve to control what proportion goes through the reactor. You'd also need a ball valve on the return from the reactor to prevent water back syphoning from the tank and flooding out when you want to do maintenance.
Or you could use a hang on back reactor.
Edit to add, heres a pic of a similar setup I've borrowed from another forum:
Not the clearest pic but hopefully you can see how it works.
