Yes, the algae is visible in the robot cleaner and the baskets and the CYA is high, so can't do the SLAM process with that high CYA. I do wonder how do we know if we have algae if we can't see it, say for my own pool. Is it recommended to do the overnight test periodically? Maddie, The pool...

So then a couple of questions come to mind, the first is how do I know that I have algae if my CC is 0 besides just physically seeing it? I could do the overnight test but then does that mean that I should be doing the overnight test periodically? Second question: Do I still need to drain the...

Hello all, I am currently helping a friend maintaining her pool, I can only go once a week and do the maintenance. On of the things that I have not been able to figure out yet is how to setup her Pentair equipment so that when I add chemicals I run her pump so that it comes off in 3 hours so...

Hello Gene, The pool is at Gilbert as well. 20k Gal IG pool, it is not SWG, it has been kept clean with chlorine tablets by a pool cleaning company. Thanks for the tip on cleaning my equipment, I am doing that right now. I have another question that came up in today's maintenance. So I went...

Thanks a lot for the read! The pool is almost brand new, it was built late last srping, so not even a year old, the read states that there could be some risks from high water tables when draining out the pool, are there any extra precautions that i need to take because the pool is new?

Hello all, I have a few questions that I need advice on. I just started helping out a friend of mine take care of her pool. She told me that she has not had had service since early December and now it is mid-late January. I checked her chemical levels, which I detail below. The chlorine...

An update on this. I called a company and they removed the calcium buildup, they did a good job. They drained the pool though so I didn't have to do it myself. Once the pool was filled they added liquid chlorine and CYA, so now to monitor the chemical levels and adjust as necessary. Thanks...

Thanks for the advice and the great read!

Thanks for the info! Yes, that is CH. Why is it important to drain and refill quickly? My thought was to drain, have a company clean the scale buildup, and when they are done refill with water, but is that not a good idea? The municipality requires the water to be drained to the sewer which I...

Hello, I am wondering if I need to empty my pool because of my high levels of calcium and CYA. If so how do I go about emptying the pool? Do I need to take any precautions? I am also thinking of cleaning the calcium spots/stains in the process. Any recommendations on how to do that as well...

Has anybody seen black spots in their cleaner? I am wondering if it is black algae, I don't see it anywhere else in the pool, at least not in visible areas, just in the pleated seal of the cleaner. I can't even scratch it off. FC: 5 CC: 0 pH: 7.7 TA: 125 CH: 1150 CYA: 140

Thanks for the video. The canister is working fine now. It is always about half full of air but the air is not going to the pump.

I have a Hayward W560 in line leaf canister that I installed in between my Xtreme suction cleaner and hose rotator. When I install the canister everything is under water so that there is no air in the hose or canister but as soon as I turn on the pump I see air bubbles getting into the...

Thanks for the explanation! I just tested my incoming water and it is high in TA and pH. pH is ~7.7 and TA ~150. It makes sense why both of those numbers do go up over time. The one thing that does not make much sense is that my pH does not change when I add the chlorine and acid. I test...

Hello all, I am using 10% liquid chlorine for sanitation and I add it every week and since my pH (7.8) and TA (125) is higher than I would like I also add 14.5% muriatic acid to bring those down. I thought that I would only had to add acid once and when my pH and TA levels were to a desirable...

A quick update: I've been adding liquid chlorine twice a week and it's going great.

Gene, this makes sense. My pool is 5 feet in the deepest part so CH may be over 400. I ran the CH test again today and got 390, I will get the speedstir and try with that. I do use poolmath, both in my phone and in my laptop, depending on where I am at. Thanks both for the advice on liquid...

Thanks all for the inputs. Here are the replies to your comments/questions: Rob: Thanks for the links. I find pool school to be very easy to understand and the approach seems very doable. My test kit is a Taylor K2006, just the 3/4oz bottles, no C in the name. A couple of questions: Why...

I live in the Phoenix metro area and I wonder how other owners in this or similar areas keep their pools sanitized, mainly between liquid chlorine and trichlor tabs. The service company that I was using to maintain my pool only used trichlor and it seems that a lot of people that I talk to in...

Hello all, My name is Jorge and I just joined tfp and I'm excited to get to mantain my pool. A pool company has been doing it for 3 months but decided to do the maintenance myself. I live in Phoenix, AZ and it seems that keeping the pool clear and sanitized requires some tweaking due to the...
