I do not run a ULN Zeo System either. I do use CV, AA, LPS, Xtra, Sponge Power, Snow and ZeoBak+Start 3. The tank looks GREAT, growth is CRAZY & the colour is as EXCELLENT. To be honest, I do not know if it is because of the Zeo products or the tank parameters finally hit a sweet spot on their own. At this point, I am not prepared to stop using the Zeo products to see if the tank craps out. In my heart, which is not very scientific, I feel it does make a difference. Then again, I could just be rationalizing the money I spend.
Has anyone tried/documented: adding, with holding and then adding Zeo products in a non-Zeo System????????
