Copper based algaecide works
For the first time in 20 yrs, my chlorine and pool chemistry got way out of whack. I started to get mustard algae on the walls and steps of my pool. After checking, turns out my salt generator had stopped producing and I was delayed in testing my pool. So I came across this AquaDoc algaecide and treated my pool. In addition to getting the chlorine and chemistry in range, this algaecide worked quickly to remove the algae on the steps and sides. I did have to brush the walls, but after a day, all signs of the algae were gone. I have always used copper based algaecides given their effectiveness.
We are using this for our water fountain, and it works beautifully killing the algae
Itβs really made for a pool, but I thought I would test it out in my fountains since it was rated so high and it works beautifully. Itβs not even that hot right now and Iβm already seeing algae around the rocks and especially if you watch my video youβll see it.This really does live up to its reputation, and the water became very clear and it was easy to use and a good value for the money. Iβll definitely be buying more but I do wanna wait and see how well it does in June and July when the weather definitely gets hotter. Now Iβm scoring a five out of five.
90-Day No Algae Guarantee
My pool has an algae problem and I ordered the MAV AquaDoc brand 90-Day Algaecide for Inground Pool to come to my rescue. As it starts to heat up for the summer, I'll do a follow-up review to see how it holds up to the 90-day guarantee - but so far, so good. If it works as advertised, this would be the greatest value in pool maintenance history of products. So fingers crossed and hoping for the best.I'm giving it 4-stars just for the expectation and will upgrade or downgrade accordingly after a 90-day review period of performance.
Works LIke It Should
Good protection for the pool and helps maintain healthy water.
