Vodka or po4 rx... which should i increase?

[kris2001]

I have an established tank with 160g volume sw..... phosphates vary between 0.1 ppm to 0.2.

Vodka dosing is 9 minutes daily like a drop every 2 sec with BRS doser. Roughly 10 ml daily. Is this too much?!

I dose phosphate RX weekly for 8 drops near skimmer mouth via perforated tube near mouth....I don't use filter pads hoping precipitate will get into skimmer...

To reduce po4 should I up the vodka or RX? I want po4 to be like 0.5 ppm

Fishes, corals doing OK.. Thx

Vodka is not an effective method for phosphate removal. I can’t make a recommendation about RX.
