Well, I've basically been just feeding this tank, topping it off, and cleaning the algae off the glass, and today I came home to 2 of my Acro frags on the frag rack RTNd. I've noticed lately that my Acro growth had slowed a little, and that I had some burnt tips on the garf bonsai colony. I've also had more hair algae lately. So I did a bunch of water tests and got these results.
pH: 8.3
dKH: 7.3
Mg: 1410
Ca: 425
NO3: 40ppm
PO4: 0.5
Obviously nitrate and phosphate are WAY too high, most likely because I feed so much food 4 or more times daily. I don't like doing large water changes, as it swings my alkalinity too much (I use well water with naturally high alk and calcium and reef crystals salt), and I already run a decent sized refugium and harvest around 2 lbs of Caulerpa every 2 weeks.
As of tonight I started vodka dosing. I am starting at 2mL daily for the first week, and will test nitrates every other day or so and see where I'm at. I want them to drop, but not too fast. I'm also dosing Microbacter7, and running my skimmer to pull a wetter skimmate. I am also going to rinse all my filter socks and sponges on the overflow pipes and powerheads daily from here on out.
