Hello all new to the forum. Here's what's been going on with my pool.... We've been in our house 7 summers now. First few summers with pool were ok. About 4 years ago got stubborn yellow/greenish algae all over the pool surface that was very difficult to vac / sweep off the sides. We got this issue 2 years in a row in August. The following year I was convinced I had a hole in the liner because I thought there was sand all over the bottom. Last year after much research I figured it must be mustard algae... Tufts of brownish "poofs" all over the bottom of the pool. They return the following day despite vacuuming. Apparently, per my local pool store, this isn't very common in PA. I followed their directions, slammed the pool chlorine levels off the charts, threw all equipment in pool and soaked it. Then treated with knockout. This seemed to do the trick until the end of summer, it returned & I repeated the process. Needless to say it's back. Every two days I'm vacuuming. Water is clear otherwise. I've aggressively scrubbed walls, shocked, treated with appropriate algaecide & cleaned my cartridges. We just got a new solar cover this year & Saturday was the first we put it on, it's a necessity as the pool temperature is miserable without.
I really just need a solution to limp through this year. We are in need of a new liner & plan on getting one next year. With that I plan on throwing out & getting new anything I can - cartridges, toys, etc. planning on slamming pool before closure to try and eliminate what's in the system.
I need to get a better test kit, just using digital test strips now. Ph was 7.2. Alk was 182. Chlorine was unmeasurable (high). To note what my strips say and what the test at the pool store reads is usually markedly different in regards to ph and alk. My "stabilizer" level was adequate when I opened the pool.
Also of note I've been vacuuming water to "waste" so it's not running through cartridges. Waiting for new pool max vac to come via fed ex.
Sorry for the lengthy post. I work 2 12s in the next 2 days so I apologize if I don't respond quickly. Will post a pic of the "mustard" algae when I can
