Some one mentioned the "off" phase this is only reccomended for new zeo tanks is this something borrowed and adapted to the matrix thing? I am lost As to why people avoid zeoliths when they are so well suited to ULNS systems
Well I added matrix 8 months(not sure) ago. Havent changed it yet. Just a cleaning once a month.
So I ask you, why use ZEO with all the extra plunging and changing?

I have no hair algae, and zeo AA's and other sups have given me great color.
