Hi currently I am running a refugium in my sump, but I am tempted to scrap it and just have reactors, instead, what’s everyone’s thoughts on refugiums vs reactors?

I hope I have posted in the right section lol

Thanks

Do you mean an algae reactor, or are you talking about running rowaphos or something instead?

If you mean the algae ones, I made one using (I think) @Marty 's design and it worked well, until my phos and nitrate got so low the chaeto died!

Only minor issue is that coralline is a right git  to clean off a curved surface!
Benefits are that it gains you space and the sump stays cleaner.

This is when I first set it up




Thanks:


Marty

Yes it was one I designed and worked very well and quite a few people on here now use that design

I was looking at running rowaphos and carbon but that algae reactor sounds and looks good I’ll have to have a look into that, what would you recommend?

What are you main aims for it? Just phosphate reduction, or nitrate too?  Gut feel is that probably the RowaPhos would be better at just phosphate reduction, but the macro algae will do both nitrate and phosphate (plus some other bad stuff like zinc and copper).

Here's marty's thread on the algae reactor:

If I’m honest I just wanted to keep the water parameters stable and not fluctuate, I started with the refugium due to hearing it reduces nitrates etc, I run either RowaPhos or Seachem PhosGuard which seems to be working well in the bags supplied, also bought some Red Sea activated carbon and then chaeto in the Refugium
