Hi fellow pool owners!
I'd like to say first up how delighted I am at finding such a wonderful resource. You are really doing a wonderful thing here. The information in Pool School/Math has probably already saved me and others significant money and hair loss. I am a new pool owner and quite anxious about the whole thing, very worried I will do something wrong, so on this forums advice the first thing I have done is acquired a K2006c. I don't want to be "pool stored" as you guys call it!
Quick background about my pool, it's about 4K gal/15K litres, 2 years old, gets LOTS of sun all day (probably 10+ hours since there is zero shade), pump runs from 6am-10am and 6pm-10pm every day (so 8 hours total). Solar heating is in winter mode now and just flushes water through once per day. SWG was set at I guess 50% (half the LEDs were on) when I moved in a few weeks ago which is now set on 87.5%. The water is crystal clear looks so inviting and no algae that I can see in sight. Everything looks to have been well maintained except...
...The water stinks. It has a very pungent odour identical to public pools that I now understand to be dreaded chloramines. Seems very unpleasant. From my reading the only cure is to SLAM the pool but I am having a hard time with my new test kit the K2006c.
I got home tonight with the new kit and decided to test pH, it was showing 8.2+ (as it has been with my previous test kit) and I have been adding muriatic acid probably twice a week, to the tune of about 300-400ml/10oz, brings it down to say 7.6 the next day but in a day or two it's back up again. But then I read that the pH test could be thrown by a high FC of 10+, so tonight even though it was dark I thought well I'll give the FC test a try. Stupid me first off decided to use 0.2ppm/25ml sample test, added the powder, and I ended up putting about 50 drops of the r-0871 in there with no visible change (the solution was red and did not even get lighter). Next up I decided to do it using the 0.5ppm/10ml sample, added my powder and I put about 40 drops of r-0871 in there, again no change from red! At this point I stopped because I was so disheartened and paranoid of using up my precious R-0871. So now I've wasted about 90 odd drops and have no results.
I tried TA and instead of turning green to red, it kind of turned blue-ish to yellow at about 70-80ppm which I read somewhere could happen, so I figure that's at least accurate, that's what my other kit was showing. I stopped there because it's dark and I will do a full set of tests on Saturday morning as I pretty much leave for work when it's dark and get home when it's dark!
I guess at this early stage and before I do anything stupid, I ask you pool gurus, would you agree that the smell is the dreaded chloramines and that my only recourse is to SLAM. And, should I have just kept going adding the precious r-0871 until it changed? It seemed really red and showed no sign of changing, 40 drops at 0.5ppm, could my FC really be 20+? Perhaps the SWG is working overtime (I mean, i did crank it to 87.5% thinking it may eliminate the CC... but hmmm yes given I don't know any other parameters yet e.g. CYA this was stupid in hindsight). I am really keen to post a full set of results to diagnose this, just worried about wasting reagents, they're like gold here in Aus haha! Sorry for the long post.
