Thanks for the reassurance all (and for the help getting me through the SLAM)!

Hi all, me again! Since passing the SLAM, I’ve not had to add any LQ to my pool as the FC levels are dropping really slowly! The last time I added LQ was on 31.08.24 (FC reading after adding was 12pm) As of today, FC is sitting at 5.0 ppm (target level for my CYA). I’ve gone from one extreme...

Hi all I’ve read a lot on here about pouring chemicals in front of a return in order to get a good mix into the pool. My pool has a single Aquagenie skimmer/return combo and when adding Liquid Chlorine in front of it, it mostly just gets sucked straight into the skimmer. Is this a problem...

FC seems to be holding well! Not added LQ in 2 days now and it’s dropping from SLAM levels at a steady pace. Did a full set of tests this evening and here are the results: FC 8.5 CC 0 PH 8.0 (probably a bit higher though as was a bit darker than 8.0 on the Taylor comparator block) TA 150 CH...

So it was another OcLT pass last night after all (5 in a row) although admittedly the loss last night was the biggest of the 5 nights (1ppm). So I’m leaving the FC to fall now and see what happens. Interestingly though I noted that my CYA was almost gone in the test I did today (always had it...

I know, it’s an indoor pool though and just comparing to the daytime losses that I’ve been seeing over the last few days. Hoping I’m just being ultra paranoid, will find out tomorrow 😂

Lost 0.5ppm FC overnight so that was 4x OCLT passes in a row. I’m really not feeling confident though after today. I stopped adding LQ this morning as a result of the 4x consecutive OCLT passes, to let the FC levels start to fall and have lost 2ppm in 13.5 hours today (between 6:30am and...

Couple of questions. When I let my FC level fall naturally from SLAM to target levels, if there is no longer a problem with the water then should it fall at a consistent rate untill it reaches target levels or will the FC level drop start to increase the longer I go without adding fresh LQ...

Thanks all! I’m just probably over cautious / paranoid as the pool seems to have settled into a pattern of having a few consecutive nights of OCLT passes followed up by a few nights of OCLT fails over the last couple of weeks. That’s just got me a bit confused about when to stop that’s all...

Another 0.5pom FC drop last night. 2 in a row again now. As a side note, I’ve bought a new vacuum head, which I’ve only used once and this morning have noticed some staining inside the weighted parts (the 3 white rectangles in the attached images). Does this look like algae forming inside it...

R0871 refill arrived yesterday afternoon. Tested 12ppm FC and 0.5ppm CC at 10:15pm so didn’t add and LQ and left it for the night. This morning, test showed 11.5FC and 0.5ppm, so the first OCLT pass in 4 days. Only things different / noteworthy last night: 1: Only 2 dead bugs at the bottom...

Thanks all! The pump has been running 24/7 for at least 2/3 weeks at this point. I’ve switched to the “new” liquid chlorine for the last few additions (I.e the Liquipak brand) so will see if that has any impact. In case it helps, I’ve done a rough and ready log of my OCLT results over the...

Not the easiest to clean the roof as the enclosure basically forms part of the boundary with the neighbours property, so cleaning the roof on our garden side would theoretically be doable but cleaning from the neighbours side would be trickier. Cleaning the inside would be relatively easier...

11.5ppm this morning (from 13.5ppm last night), although it was 10 hours between the tests this time which isn’t ideal. This morning there were more dead bugs at the bottom of the pool then I’ve seen before (maybe 8/10 dead wood lice). I never (or rarely) see any at the bottom of the pool...

I’m really wondering how much of this is down to user error / user variations in the tests at this point (meaning me 😂). I tested 11ppm FC at 7:00pm tonight then added 500ml (of the new Liquipak Liquid Chlorine for the first time as suggested) straight away. I tested again (twice) an hour...

Lost 1.5ppm overnight last night, after only losing 0.5ppm overnight for the previous 2 night!! How much should I take the test tolerance levels into account at this stage (ie +- 0.5 / +-10% if using over 20 drops)? How much of an impact can bugs at the bottom of the pool have on FC...

Test 11:00pm: 12ppm FC Test 6:30am: 12.0ppm FC / CC 0.5 My heart sank when I tested this morning as I got 9.5FC and 1.5CC! I thought that can’t be right though so I rinsed the tube out and tested twice more and both of the other tests have 12pm FC and 0 CC. Would it be safe to assume that the...

Only seen 0.5ppm FC loss since topping back up to SLAM level 7 hours ago (currently 4:30pm in the U.K.) 🤞

Have received the MSDS for the Liquipak liquid chlorine (the product I’ve not yet used, mentioned above). Not sure what I’m looking for though so is there anything here that doesn’t look so good?

I hadn’t noticed that! There’s no mention of a stabiliser anywhere else on their page or on the packaging so I’ve just contacted them and asked for copies of the specification and Material Safety Data Sheets to see what they show: I’ve also recently bought this Liquid Chlorine but am yet to...

I believe that’s the heat exchanger from the boiler

Test 11:09pm: 12ppm FC Test 6:20am: 12.5ppm FC / CC 0.5 (did 2 tests this morning, using different batches of reagent for each and got the same results) I guess the rise in FC can just be down to test tolerance / variation but it looks like a pass! I’m working from home today and we have a...

Yeah. I do lose FC during the day but for the last few days it’s seemed to be minimal and then ramps up in the evening and overnight (not huge losses, usually 2ppm but more than it lost during the day. It’s an indoor pool too so UV is also relatively minimal anyway. Water is crystal clear to...
