    Confirm this is trowel mottling?

    maybe this shows it a bit clearer, the bottom has some areas that are distinctly grey, with others that are a much brighter white.

    Confirm this is trowel mottling?

    Hey guys, I had the pool half drained over the weekend (was exchanging water to get rid of iron from bad salt) and got a chance to look at what the surface looked like dry. Since we have owned the house the pool has always had a mix of white and grey mottling. From my reading I assume it is...

    VitC test leaves a trail of brown

    Hi James, I've never used a metal based algaecide in it but the pool was 2yrs old when we bought the house, I do remember there being a bottle of algaecide left in the pump enclosure. The original color is a good question, it's white with a blue and white quartz speckle by the looks of...

    VitC test leaves a trail of brown

    Yes pure powder, have made the mistake of using orange vitc tablets in the past. They don't really brush away but do lighten a bit, running the pump now to see if they lighten up. I was thinking copper but the brownness of the stain as opposed to grey put me off. It hasn't had any copper since...

    VitC test leaves a trail of brown

    Hi folks, Trying to figure out some stains in the pool, I chucked some acetic acid in some skimmer socks and put them on the stained area in the deep end of the pool. 5 minutes later I notice something very strange, there is a streak of brown coming from where the socks are. Any ideas what...

    AA treatment - When to call it quits...

    Beginning to think that some of my stains (the ones I tested with vit c) were iron, maybe these ones aren't. Possibly could be copper, I've never added any to the pool but the previous owner did leave behind a half used bottle of the cheapest algaecide he could find...

    AA treatment - When to call it quits...

    Doing an 'opportunity' based AA treatment. By that I mean the pool pump was left off by accident, fc dropped to zero and I was lucky enough to catch it before algae. My stains appear to be iron from vitamin c tablet test. But here's the thing. My pool is only 20K litres, and I've dosed 750g of...

    First SLAM

    Every 4 hours or so definitely sounds like something growing. Mine was only coming back over the course of a few days. Also i wasnt getting any of the white milky dead algae that you are seeing. The bucket test didn't grow any algae or dust. But passing two OCLT tests and crystal clear water...

    First SLAM

    Well yesterday I pass the OCLT. In fact it went up 0.5ppm overnight, but at 40 drops for 20ppm that's probably within the margin of error. Let the chlorine come back down today. Brushed the pool and there is a fine layer of brown coming up, but honestly I suspect it is fine dust. Doing another...
