Good afternoon! I am new to TFP, but have been reading the forum for a few months. I finally signed up after battling mustard algae that won't seem to go away.
I had a severe mustard algae outbreak last September before I realized that the "dirt" on the bottom of my pool was a type of algae, as I am a new in-ground vinyl pool owner. I got rid of it by using Mustard eliminator (99% sodium bromide) and vacuuming to waste.
I maintained the pool all winter with no problems. Now since March 15th, I have had three separate mustard algae blooms, although I caught these very early. I again used the Mustard Eliminator, but was able to get rid of the algae using only the sand filter and backwashing once since I caught it so early.
My question is why is this algae coming back every two or three weeks? I maintain FC between 1-2 and have had no CC's until now (.5), and also use a nonmetallic algaecide weekly. Is sodium bromide the way to go?
All testing done using the TF 100 kit that I purchased after reading this forum.
Please help! Thanks!
