Default How to reduce PO4

My tank have been doing great... however 2 weeks ago I got a moorish idol so my feeding quantity went up ... well about 4 times I however notice my PO4 increasing also NO3 but NO3 is only about 1 ppm and I can always increase flow through reactor for that since my flow currently is at the minimum. My question is how to reduce PO4 ...algae scrubber???? Phosphate absorber??? Any input is appreciated.

Please post some more details about your system, otherwise it is difficult to give you a recommendation.

The combination with PO4 absorbers is not recommended, main problem is the quick changes in the PO4 level while adding them which will have a negative impact to the corals. Looking forward to the additional information of your system.

Thank you for the details. The PO4 level is elevated however not massive high. I think you should be able to decrease it slowly by doing some changes:

1. Increase the ZeoVit quantity to the recommended amount – 130 US gallons = 1.2 liters with a flow of ~ 130 US gallons through the reactor. Do this in two steps over 2 weeks. Replace the material every 6 weeks at the moment, later you might be able to lengthen the interval.

2. Dose 5 drops ZeoBac 3 x weekly, 0.5 ml ZeoStart 2 x daily and 10 drops BioMate every other day. Continue the other products you use as you already do.

3. Adjust your skimmer to skim more wet and clean it regular, if possible daily to export as much as possible. Monitor the K+ level if doing this change.

Please post a update in about 2 weeks.
