Prodibio is another company who caters to the reefing community with several types trace elements, and carbon sources + food for the bacteria. Assuming you are following the correct product and dosing regime suggested by Prodibio, you are in a nut shell trying to recreate a low nutrient system. Zeovit is very similar in the respect of trying culture a source of bacteria. The difference is that the bacteria is cultured in the zeolite rocks. Zeovit in my opinion requires more work that prodibio, eg. you have stir the reactor once a day, change out the media every 6 weeks, cannot miss bacteria supplement doses, your parameters must be bang on, or your corals will be super sensitive due to the low nutrient environment.

I suggest stay with one kind of bacteria source whether its prodibio, zeovit, biopellets or carbon dosing. These methods are not meant as an easy way out for maintenance, you can find lots of articles on each one when you Google them. Running GFO depends on the remaining phosphates your bacteria can't handle, you have to make the call for that. I have seen lots of people run GFO with carbon dosing, but not as much for zeovit tanks. If you are getting hair algae, these methods may or may not be the way to solve it. In my opinion it isn't the best way to solve your issues, there is excessive nitrates and phosphates coming from your tank and it is best do water changes, run GFO, manually pluck it out, have a clean up crew to take care of the finer pieces and try to find the source of the problem.

What kind of inhabitants are in your tank? SPS dominant? LPS? Softies, a lot of these dosing regimes have adverse affects on the types of corals since different groups of coral demand different nutrient conditions.
