Who Doses Carbon?

[RYcube2951]

I have a Coralife Biocube 29G reef setup. Mostly softie corals and 3 fish. Filtration is Eshopps sponge, Tunze 9001 skimmer, and live rock. I do a 10 -15 percent weekly water change and make my own saltwater. RO/DI water and a quality salt mix. Feeding Blue Zoo mix (dry food) daily and Red Sea AB+ coral nutrition 2 times weekly (1ml per dose). I test my water with Nyos kits. Typical Phosphates are 0.25 and Nitrates are 20. I have some snails that keep my rocks clean but my sand does have some brown algae patches. I would like to lower both Phosphate/Nitrate and have considered dosing a liquid carbon or Phosphate E (lanthium chloride). Has anyone tried these methods?

I carbon dose. Using a diy version of nopox. Vinegar and vodka with a little rodi wate. Your nitrates aren't too bad but phosphates are a little high. Try to get nitrates around 5-to10ppm phosphates around .03-.1ppm
