Hello, I Started using both about 6 months ago (give or take) I would alternate both each day and measure Nitrates and phosphates. If either is to low then stop the ProBio for a few days and re-test again.
The other thing I would say is (this is optional lol) once you've been dosing for a while, depending your system parameters, size organisms etc, you could reduce your filtration. I found that my system was thriving just dosing the two daily and just running on an ATS. The skimmer was "on" but didn't really produce much, so I removed it.
I thought about using a dosing pump for both, but the yellow snow needs to be chilled. Both products must be sealed very tightly, so the dosing container needs to be top quality to avoid the products coming into contact with the air.
The last piece of advice is the product needs to be dosed consistently to see/maintain long term results.
Hope this helps!
