          Rayemail, first of all welcome to our community

          Thanks for posting the details about your system. Indeed your present dosage looks a little bit high to me and I would recommend to cut it down until your tank contains the first corals:

          ZeoBac: 6 drops every other day after you have changed the zeolite for a 2 week period, otherwise 6 drops twice a week.

          ZeoFood: 6 drops every other day after you have changed the zeolite for a 2 week period, otherwise 6 drops twice a week.

          ZeoStart: 0,5 ml in the morning and 0,5 ml in the evening every day. Not sure if you already use ZeoStart2 but this does not matter to much.

          I would recommend 1,5 liters zeolite (ZeoVit) in a zeovit reactor, mixing the zeolite daily. The water flow through the material should be around 400 – 500 liters per hour. I also recommend the usage of 0,5 liters PO4 carbon in a filter sock, placed in a passive water flow in your sump. The carbon should be changed every 30 days.

          AminoAcidHighConcentrate would be a good nourishing for your corals now. A daily dosage of 2 – 3 drops would be adequate.

          Please make sure you have read the Zeovit guide which you can easy download as a PDF document from this location:

          Try to read it over and over until you feel you understood the system. In your case I would recommend the process with the dosage of phase 3. If you notice any overdosing signs, the dosage has to be cut down again.

          Your observation with the lighter tissue could be a result of the strong dosing.

          Please feel free to post further questions.
