I previously had some issues with algae this season (first year owning the pool), but I SLAMed it and cleared it up. It's been a month now and the water is still crystal clear, the FC has stayed at ~6ppm with no issues, CC is around 0, and no dips in chlorine levels from what I've seen (SWG pool). It's a fairly large pool, 17' x 40' x 12.5 (deepest end), and only has 2 return jets. I've angled them to try to get good circulation of the water. I also scrub 1-2 times a week, sometimes more, depending on if I'm outside already to swim.
Anyways, I've noticed that there are spots around the pool that tend to get some small algae growth during the week. Around the stairs (built in) there are some spots that get a little green, when we were swimming a few days ago some of the walls had a very slight slime feeling to them. Some of the nooks and crannies, or chips in the plaster, and in the lattice work under the deep-end ladder, seem to get slight algae growth in them. I focus on these areas when I scrub the pool, but I was wondering if this is normal.
It seems to be in places where the water isn't circulating well to, but the chlorine levels are high enough and the CC has never been more than .5 (the test barely gets enough pink tint to require a single drop to turn it back clear). The scrubbing is supposed to help circulate the water some, and I assume swimming has similar effect as it's getting moved around by people instead of just where the jets send it to. So is there something different I should be doing? Is this normal, as long as it doesn't get out of hand and the chlorine levels stay steady, it's fine? After my previous issues and SLAMing the pool for weeks, I'm trying to avoid having another issue this season.
