Hi! I am feeding the AB+ every other day, the instructions say to feed every day, I tried that, but after few days I get a little algae bloom. What's everyone's experience with this new coral food?

In my experience it with A and B they really doesn't contribute much to waste levels. AB+ is pretty much just the two combined so I would figure it is similar. You only have to feed everyday if you run the red sea care guide (uses carbon dosing and very very low nitrate and phosphate) which limits your corals access to nitrate and phosphate, forcing you to feed the corals.

Oh, I don't really follow their guide, I dose alk and ca.. do a 1% daily water change.. and dose vinegar to target 2-5ppm nitrate.. corals are doing great, not sure AB+ is doing anything more than just feeding with frozen food..

It definitely is different than frozen feeding as cnidarians and corals can take up the reef energy through their polyps with out having to capture and break down prey into its basic structures. Vinegar dosing is the same as nopox so it shouldn't hurt to dose everyday. Do you do the recommended amount? What is your phosphate at? Also, what kind of algae?

It’s some sort of green/brown patina on my glass.. the trochus snails are doing a great job at it, but still.. no algae on the rocks or at least they eat it before I can see some.. I got 10 big trochus for 25gallons

Do you know your phosphate level?

The solid 0 Nitrate is causing the algae.. 0 Nitrate is a common cause for dinos which might be what's on the glass. No matter what it is or what your overall solution will be.. step one... is clean all you can & raise nitrates to a level that creates a decent ratio range with phosphates. If you're feeding keeps everything happy and phosphates at that 0.07 range (which is good) then just use a nitrate additive to strategically increase only nitrates. Like neoNitro.

My phosphate is 0.07 nitrate is a solid 0, I will try to raise that, I am already feeding the heck out of them
probably just reduce the amount of vinegar dosing if nutrients are low. In a 25 gallon overall tank nutrients should be handled mostly by the water changes each week so the vinegar dosing may be overkill

I definitely get some cyano if I dose AB-+ every day. I dose 1-2 times a week when I can remember and that seems to keep the tank clean of cyano but the corals still get the benefits of the dose. The bottle says it will not contribute to algae but nothing about cyano. My nutrients are always super low and AB helps to keep everything from bottoming out. Plus it’s fun to dose cause of the color
