Super. Thx

I used to have a good one that was recommended around these parts but it's been a while since I owned a pool Been using strips and winging it because this pool had much larger problems than chemicals. Has been pretty much smooth sailing in terms of chem the whole year just curious about the CH...

Tested at two different stores, with a bit of time spread between them

Read some differing opinions on this... 200 minimum, or it doesn't matter I have an old pentair 125 heater that is well out of warranty CH in above ground pool (vinyl) is 118. Also has SWG. Water in area is naturally quite hard and I've filled quite a bit this year due to repairs and waste...

So, I have passed the overnight test. Time to take it down and start swimming again!

So latest update, re-examined area around light, i think it was just painted poorly as there are globs of stuff all around it. So I'm over that. REGARDING the water, it now looks as clear as it ever did. I was away for one day (but had my dad drop in 182oz of bleach on Sat eve), came back as...

ok so reading tonight was a bit high after adding bleach (around 25.5ppm). i noticed today when brushing that near my light there is a few significant patches of what appears to be the surface coating chipped off near the light. I think I may have done this with the new wire brush I got :/ I...

I dunno, I saw some people on this board recommending polyquat at times for inhibiting algae growth in the future. I know BBB is the standard here, but I was wondering if my situation was unique with the constant leafdropping and hence organic material. I am probably going to try to scrape...

Ok thanks. Today recorded an overnight drop of 2.5ppm (25ppm > 22.5ppm). The big wildcard in this is going to be if they high chlorine level is enough to kill any algae that might be present in the light. I really can't do anything with it until the whole thing is fixed (and breaker...

BTW, poolcalculator is amazingly accurate. I wanted to get it back up to 25 earlier in the evening, so I added what should be the right amount from poolcalculator and it hit 25 on the nose! Anyway, this was the chart I was referencing: chlorine-cya-chart-t2346.html This one says mustard algae...

day 1: reading 10:30pm: 22ppm (probably did not have enough time to mix) day 2, reading 9am: 25ppm reading 6pm: 16.5ppm added another 4 gallons of bleach. Overall things going well except I'm having trouble brushing due to the chlorine smell which is irritating my lungs. :( After the...

First morning test 25ppm. Looks like it wasn't fully mixed last night when I tested it, which is understandable. Here is a question, though - when brushing this morning I hit some patches that may have been missed yesterday,and while brushing them I got some yellowish/orangish dust clouds. Is...

Ok, at 22ppm FC Sometime tomorrow I'll dump the pool tools in there. How long do I leave em in for, a few hours?

Added 1250oz of bleach. Could not remove light as don't even know which breaker it is on, if it is live or not, and if it is wired properly. Will test tonight and see how it goes level-wise. Quick question, with pool rafts, can I scrub them down with a something like Lysol? I only ask...

Some great advice here, thanks all. First off, yeah I have the Taylor K2006 with the DPD chlorine test. I got the kit a while ago but haven't mastered it until recently. If I got this kit earlier on and mastered it instead of using the el-cheapo brand I probably would not have this algae...

Follow up question. The other day when I thought the algae was gone, we went in the pool, and then into the spa. Is my spa now at risk? if so, what to do? Note spa is covered and has silver ionizer cartridge. For the hot tub I use Hot Springs MPS Shock every time prior to use, and Enhanced...

I have a K-2006, yeah I have measured 10+ppm with it before. I wasn't sure at first but now i'm pretty sure its algae too. Unfortunately my last shock yesterday I used Trichlor so my CYA is likely higher now, will have to retest tomorrow. Here is a question to both of you. So lets say I get...

I just threw in a heap of shock so it will be off now, but I can give you my results from this past Saturday: Free Chlorine - 5ppm pH - 7.4 Alkalinity - 150 CYA - 40 One other thing I failed to mention, when I threw in the 9lbs of shock about 1.5wk ago the FC level was >10ppm for 2 days...

Hi all, First post here looking for some help. I want to verify the best thing to do given my situation, hope I could get some feedback. Background: 1) Approx 30k gallon kidney pool - sylvan from 70s, two skimmers. Water about 1.5" higher on one end than the other. 2) 70s hayward sand filter...
