    I ordered this along with Cal Aqua Labs other additive and so far its been really nice. I use Seachem flourite and wanted a nutrient base to my substrate system. Its been a few months and I find I actually dose less fertilizer than I did with my previous tank. I leave town for work quite often and this system has been a life saver. I dont rely on my wife to dose my tank and everything seems well and stable. Really enjoying Cal Aqua Labs Multi_r and Substrex.
