I'm not sure how sensitive the Hanna Checker is compared to the D-D Merck kit, but even people using Zeovit rarely get down to 0.00 ppm phosphate using the Merck kit. Getting to 0.08 ppm is doing quite well. Keep in mind that if you have any algae growing in the tank the true phosphate level will be higher as the algae are sucking it out of the water column as it grows. Sometimes, but not always you can get a higher phosphate reading if you test in the morning before the lights come on. You're doing everything right regarding phosphate.

As far as Zeovit goes, have you joined the Zeovit forums yet? Which Zeovit products are you using? I would suggest you just use the Zeolites, Bak, Food, and Start to begin with. Don't start using any of the other additives until you have removed your tank of every little bit of algae. Absolutely do not follow the directions on the bottles when it come to the other additives. I was using 1/4 what the bottles said and got the best results that way. I was not able to dose Iron or B-Balance without getting algae blooms. If you get diatoms or cyano when you start the additives you're dosing too many additives.
