Understood. Bringing it up to get in line with salt cell recommendations (200-400). Also, experimenting if it will affect freezing point in winter since I don’t close pool. I know it takes much higher TDS levels, but only looking for one degree. Long shot.

Does anyone else do this when adding chemicals? For example, this is a 20 pound bag of Calcium Chloride, but at only 94.8%. So in PoolMath, I put I added 18.96 pounds. It’s only a 4ppm difference, but the nerd in me likes to be exact!

UPDATE: Today I took a dental scraper pick thingy and I scraped the spots. They did come up. I still don’t know what the heck they are, but at least I know it’s not something embedded in stairs.

My other thought was that there is like a metal fiber in the plastic steps binding it together and the plastic is wearing away exposing it.

Maybe. Could birds carrying it in? I do my own fertilizer and am pretty careful. The grass is far enough from the pool. Would it embed in the plastic like that? If so, how do I get it out?

Love it!

Need some help please. I noticed rust stains on plastic stairs. Brushing the stains does nothing. Comes off with vitamin C tablets. But there is still a tiny black dot there afterwards (those are the specks you see in the pic). Almost like an embedded piece of metal. I put a strong magnet...

Pretty good assumption that that is Florida!

Looks like a sandy loam. Are you seeding or sodding? Sod will have a bit of top soil. If seeding, you can mix in some top soil or soil conditioner to help. Grass can grow in some harsh conditions. Water and sunshine is the key. P.S. If it is mostly clay, then add sand instead of top soil...

In the past, I have had a new build gunite pool with plaster finish and SWG. As expected, my pH was always on the rise and I controlled with muriatic acid. Now my pool is vinyl with a SWG. I have jugs of MA anticipating the pH rise, but it just is not rising. It just stays at 7.8 all the...
