Hi All.. Here in south alabama, for the month of june, we are up to over 6" of rain. To avoid using my cya test kit so much can I estimate the cya based on salt level? For example: The measured salt level is 3200 ppm ±200 The measured cya is 70 ±10 In a give amount of time I measure salt to...

I had no idea the chlorine would be more harsh. Thanks for letting me know.

No real reason for no cya... just hoping I could get away with putting none in. Thanks for the info.

Hi All. After 2 years of having the pump off and no cover I recently reopened the pool. I'm getting really good at turning a frog and mosquito pond back into clear sparkling delight! :) I was thinking about removing the swg and manually dosing the pool. Currently there is no cya or salt and I...

I found a Century for $264 shipped. Thanks.

Hi all. My pump motor has bit the dust. I'm looking for a replacement. The cheapest I have found is $289 plus shipping. I'd like to find a cross reference that may be a bit cheaper. Can anyone help? Or, is there a cheaper place to find an original replacement? Specs: Hayward Super Pump 2...

I'm about to install a stenner pump in my g/f's pool. It's approx 30,000 gal. I also plan to purchase chlorine by the 55 gallon drum at 12%+ strength. Some questions. Question 1 All things being equal... Drum #1 has both 2" bung caps off so the chlorine is open to the air Drum #2 is sealed...

The barrel has been exposed to direct sunlight several hours a day for probably 3 weeks now. Most likely the temp of the liquid has risen above 90 degrees. On another note... The polaris (3900) had not been working properly. The drive chain would constantly come off and it didn't have enough...

That's good news. A friend who has a power washing business gave me a 55 gal drum that is over 3/4 full. When he purchases the drums, they are listed as 12%. I've seen the chart that has the concentration curves. I'm thinking about purchasing a 55 gal drum for my g/f's pool at the beginning...

Just to be sure I'm reading this correct. I mixed 1ml chlorine in 100ml distilled h2o then mixed 1ml of that in another 100ml distilled h2o. I took 10 ml of the final solution (10,000:1) and tested it using the FAS-DPD method. It took 11 drops make it clear. So, does that mean the chlorine %...

Too late. :P Well, I didn't spend big bucks though. I already purchased a set of 5 beakers and 100 1 mL pipettes which was way cheaper than the taylor test kit. My purpose is to get a rough idea of the strength of chlorine and to have fun with some chemistry. Besides, I do not use liquid...

Thanks for checking your cylinders jj. Wetchem, I wish could spend $335 on a 2 mL pipette. I would have all kinds of cool chem lab stuff if I could. In my case, I need to both deliver and contain. First deliver 1 mL from the pipette into 100 mL distilled water. My purpose for testing is not...

I just pruchased some 1mL plastic pipettes and some glass graduated beakers for testing chlorine concentrating using 10,000:1 dilution. Just for kicks, I took a 1 mL pipette and filled up the graduated containers that come with the tfp test kit. I filled the pipette up to the 1 mL mark and...

I was shocking my pool and the cya was around 70 so it required a lot of chlorine. Also, I wasn't able to maintain the shock level because of work so the process took longer. So this one day the pool store guy said, "you sure are using a buncha chlorine." I told him I have mustard algae to...

thanks. yeah, cut just a small amount like a typical grecian style pool.

If the pool is approx 16'x32' grecian and the level rises 1"... That one inch of water adds: 16x32x.083 = ~ 42.5 cu feet x 7.48 gallons in 1 cu foot = ~ 318 gallons Aside from the pool not being exactly rectangular, is my math approximately correct? Thanks.

I have an RJ45 on a 19k pool and have had no problems with it at all. Definitely get the upgrade. They have a 7 year warranty and it's better to have too much than too little.

Thanks Nodnarb. That was helpful. I really don't want to add a suction line to my pool wall, but it looks like that may be the only option.

This pic was taken before I renovated my pool. It is a pic of the turbo skimmer. I'm really not sure what the point of the turbo skimmer was, but it's a crazy (silly) design in my humble opinion. The pic shows the sleeve slid to the left and below the sleeve is the actual suction line that...

I think we have the same thing. If so, that is called a turbo skimmer. The return is routed through the skimmer, under the basket, and out to the pool. Does this sound correct? If that is the case, it would be impossible to use the MX8 with the connections that are provided. (I assume)...

Way out! Thanks for the chart. I missed that one somehow.

The cya chart in pool school does not have a column for mustard algae. I used the pool calculator for my reference. It suggests FC at 39 for cya of 70.

Remember how back in my first post I said I experimented to see how low I could get my FC before there were problems? Well, that was a STUPID idea! I should pass the OCLT tonight, but not before I have used a total of 22.6 gallons of bleach. And, 10 gallons of that was 10%. There will be no...

Oh, BTW Be careful if you go to a chemistry supply store to not ask for the wrong thing. For example, If you go in and ask for a couple of 4000ml beakers, chances are you will get taken to the ground right there. There is a list of things that dope cookers use in their kitchen. She told me...

Sometimes I go off on tangents. Because I have this fancy accurate test kit I figured I could determine exactly the molarity of the bleach I'm using. So, yesterday I went to a chemistry supply store to look for some beakers, flasks, pipettes, etc... in order to measure exactly the volume of...

Ok, ok. :wink: Before I began shocking, the cya was 70. Over the past couple of days the heat has evaporated some water, so last night I added approx 500 gal and backwashed for a long time. After that I gave it a good rinse. The cya is still very close to 70, but just for chart sake I said...

I'm not sure if it was coincidence that I had pollen and mustard algae at the same time, or if my pollen was really MA. Here is that thread It all started with an experiment to see how low I could get my FC without problems. At FC around 7 or so, I got what I thought to be pollen. I felt it...

So, I had a huge amount of pollen in the pool. Gathered on the floor like the sands of a desert and stuccoed the sides like an adobe hut. It truly was a sigh to behold. After an hour and a half of painstakingly vacuuming the sides and ever so slowly and delicately sweeping the bottom as to not...

I think it is pollen. It sure does cover and clump like algae. I felt several patches and it is gritty instead of slimy. What a relief. I never imagined that there would be so much pollen in the air. There are about 7 large pine trees that hover in the vacinity. I guess they dump pollen at...

Is that a bad idea? Would the borates take care of the algae? There is not a huge amount of algea, btw
