Love the site. You guys have been such a big help in getting my pool straightened out. I'm coming up to speed on testing at home and keeping the chlorine levels stable. First post. My pool is clear right now.
Background: House was a short sale and the pool was black for about a decade before I bought it. The plaster surface is in really bad shape and de-laminating in many places. Calling the plaster soft would be an understatement. Staining is rampant. It will be two years before I can re-plaster the pool after the interior remodel is complete.
Question: There is a thriving population of green algae growing UNDER the plaster that invariably starts peeking out around the delaminated areas even with FC at 2. I'm struggling to keep things in check without reverting to algaecide. Considering my test results, would SLAMing be effective in my situation? What chlorine level should I maintain after I SLAM? 3ppm? 4 ppm? Any other advice on how to best ride this out for the next couple years?
Many thanks in advance for your advice.
