Okay, this will be lengthy but I am trying to get good enough at this that I don’t have to bother everyone on here as much! I THINK I must have iron in my water. The brownish stuff that usually accumulates does so directly under the jets (especially the one closest to the pump.) It is very fine – like sediment. If I brush my hand over it, it goes away, like powder. Again, I think this is sediment and I’m not real sure what to do about it. The Polaris doesn’t seem to get it and neither does the filter. Anyway I think there is iron in the water too because my vinyl steps and the skimmer boxes and even the jets have a brown “haze” on them. Sometimes if I rub them pretty hard, they will get better, but never go away. I don’t notice it on my liner though. It really only seems to happen on vertical surfaces (like the face of the steps – not the flat surface). Even when the water is crystal clear – the haze is still there. The water is terrible right now, but I think that is from large amounts of sediment. That has nothing to do with the brown haze or stain because it’s always there. Vital signs are decent:
FC : 8.5 (due to CYA and thought the dark water was from algae)
CC: .5 (maybe partially because of the sediment)
TA and CH : 90 and 120 (don’t remember which was which)
CYA: 55-60
pH : hopefully down to 7.6 (always runs high due to SWG)
Salt: 3500
Few Questions:
1. Does this sound like iron? (not very confident in local pool store)
2. Is it normal to only see it on the steps, etc. or is it just because they’re white?
3. Should I get some Vit C on the way?
4. Do I need to always add sequestering agent now if I have metal (what is it anyway)?
5. Any suggestions on sediment?
Thanks for reading,
