I liked SpectraPure's double reactor. One line in that splits with separate controls to adjust each and one "Y" return all for $75. Another Nextreef is $110 and I like that I now have my sump in the basement I can mount SpectraPure's on the wall for ease of maint.
I purchased a SpectraPure dual reactor for GFO and Carbon. I am currently running just a Nextreef gfo reactor. 65G tank with 30G sump setup. What quanities of each should I use in the reactors? Thanks!
This happened to a friend of mine. Since then I have the hose into my calcium jug fit snug and slide it down an inch below the surface and adjust it as calcium is used up.
