GEO Calcium Reactor 612 vs Korallin C1502

Can anyone please tell me which model is better to get.

thanks

 

Hello, with the new search features on the site, have you looked back to see what comments others have posted?

 

ok, thanks.

I only found one, and GEO is what they like.

anyone else?

 

I use a geo and love it.

 

Yep, GEO's are the best. They have been making them for a long time and have them figured out. I still have yet to see another reactor brand that is as efficient at using CO2 as the GEO's. That means no low ph issues, and less refills of both media and CO2.

 

Thank you both very much. That’s exactly what I wanted to hear.

Geo it is.

BTW, do you guys use pH controller for this unit? I have 90G, should I get the 612 or the 618?

 

I use a Ph controller with mine(Apex). Size will depend on your calcium intake but the only down fall with getting one on the smaller side is more media top offs
