Hi R2R!
As the thread title states, I need some help to ID this algae and then best course of action to eradicate it from my tank. I've been battling this algae for over a month - it started when I went on vacation for two weeks. When I returned home, I did a 20% water change, I siphoned as much algae as I could, and even took some of the rocks out that had the most algae and scrubbed them with a brush.
My parameters are below:
-Alk - 8.0 (redsea test kit)
-Ca - 430 (redsea)
-Mg - 1600 (redsea)
-Ph - 8.1 (Apex Ph probe, calibrated last week)
-Phosphates read 0 for RO/DI water and tank water - using salifert test kit. I run Rowaphos 24/7 anyway.
-Nitrite - 0 (API)
-Nitrate - 5ppm (API)
-salinity - 1.024 (Apex salinity probe / confirmed with refractometer)
-temp - 77
I do a weekly water change of 2.5 gallons (10% water volume). Alk is dosed twice daily (I think 4ml total), Kalk is dosed 4 times a day to maintain Ca and Alk. I manually dose Mg maybe once a week just to maintain it, although it is a bit high right now so I have not dosed Mg in over a week. I also dose AcroPower every other day and I spot-feed my corals with reef roids weekly.
I have two clownfish, they are mostly fed frozen mysis and brine soaked in selcon once a day.
CUC consists of a mexican turbo snail, an emerald crab, and a margarita snail. I have a fuge chamber full of chaeto and I also have some dragons breath in the display.
I'm posting a few photos of the algae, including a few that I took under 250x magnification.
I'm thinking silicates might be the cause because my phosphates are 0. Anyone know how I can confirm this?
Anyhow, any help would be greatly appreciated!
Thanks!
