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?

Thanks
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.

@Elisonex welcome to ReefBase  :D

Yes, you can run one externally.  Do be careful if you're making a DIY one, as I've read about the heat from the lights cracking perspex.  I'd be inclined to copy a design someone has had running for quite a while.

Re. flow rate: I'm not sure too much experimenting has been done yet.  Really, you just need to move water through a reactor, provide appropriate wavelength light, and have nutrients available in the water, and it will grow.  I have the impression that more flow is a good thing.

Yes cracking has been seen however Shane has now done this to help with heat soak

When I started the topic I only obvously ever got to a MK1 design and shane has now come up with a MK2 to help with heat soak and hopefully no chance of any cracking.
