Which zeo products cause bacterial film/growth when overdosed?

[Tom Berry]

My current dosages on my 75 are: 2 drops bak and food 2x weekly (EOD 2 weeks after changing zeolites), 1 drop AA, 2 drops PIF and 1 drop iron 2x weekly. I am not currently using start (I will be starting start 2, as soon as I get it from Madison.).

I have bacterial film on my glass and rocks, and am wondering which dosage(s) to reduce.

Hi Tom, when did you stop start1 in this scenario? Do you allow > 6wks. between zeolite changes? Is your RODI product water high in TDS? Is your zeolite filter flow > 100gph/100g net volume? Are you using <1ltr. zeolite/100g net volume? All of the above, along with excess bak,food7, & start1 can result in brownish/green thick bacterial films, slimey accumulations as well as coral consequences. Bob

About 6 weeks ago.

Do you allow > 6wks. between zeolite changes?

no

Is your RODI product water high in TDS?

no, 0

Is your zeolite filter flow > 100gph/100g net volume?

no

Are you using <1ltr. zeolite/100g net volume?

no

I guess I will try reducing the bak and food7.

Will AAHC cause this, as well?

Hi Tom, yes, AAHC & any of the zeo-supplements in excess will cause a thick film accumulation or slime build-up. With the proper ZS2 dosage, reduction of Food7 by 50% quantities is recommended. I also would recommend dosing Fe only once/wk. Have you tried holding all zeo-supplements for a time[1-2 wks] to see if these are a factor here? Bob
