A/C Sea Strainer and Chlorine Tablets

[capav8r]

I have an idea that I thought I would float by the gallery. I get quite a build up of algae in the sea strainer for my ac and was thinking about dropping a couple of chlorine tablets that they make for swimming pools into the intake side of the strainer. I am thinking this might prevent the build up in the strainer and pump, along with the plumbing to and through the a/c unit. Any thoughts?

interesting.......the only thing I'd be concerned with is chemical interaction with the internal parts of the system.....ie the coils and valves inside the system......

might try to use maybe 1/4 tab inside the strainer and see how that works out first...wait a few weeks and then try another...I wouldn't try a whole tab..

So, I went ahead with this experiment about 2 weeks ago. Strainer is as clean as a whistle. I was a little concerned that it would bleach the finish on the hull beneath the thru hull, but that hasn't happened yet. Granted, our water temps are still pretty cool and the algae hasn't started to really bloom yet but it looks like there are no negatives so far. I think those tablets are pretty slow in their release so once some flow starts going through, there probably isn't much concentration in the discharge water. Then when the flow stops, it has a chance to release into the water inside the strainer and keep everything clean. This might just become SOP for me from now on.
