Any ideas as to what type of scaling I am dealing with? FC 4 CC 0 TC 4 pH 7.5 TA 100 CH 260 CYA 30 17,500 Gallon Fiberglass Pool South Arkansas See attached pictures. Thanks

Hi all, Just now in the beginning stages of shocking a green, algae infested in ground fiberglass pool. I used a regular pool brush and did a decent job of knocking off some of the algae stuck to the walls. However, the circular looking spots act as if they don't want to come off with just the...

I plan to put CYA in a sock this evening and imagine it will be gone from the sock by tomorrow sometime with a little coaxing. Can I go ahead and start shocking my green pool this weekend...or will I backwash out too much of the CYA by starting this weekend? I was really hoping to get started...

I've discovered an issue that is brand new to me after successfully testing and balancing my chemicals in the same pool for 3 years. For whatever reason, I can't get a pH reading that corresponds to the color shades on the vial. I've used three different brands of phenol red and I get a very...

I own a 17,500 gallon inground fiberglass pool in South Arkansas. Due to the cooler weather, I've been slacking with my tests. The other day I decided to test my pH and I got a very reddish color...one that doesn't fit into the color spectrum on the test vial. I assumed my pH was extra high...

I live in South Arkansas and have a 17,500 gallon inground fiberglass pool. I'm considering not putting a cover on the pool because it's such a hassle pumping water off the cover, removing leaves, etc. etc. We also have new landscaping around the pool and it would be nice to enjoy the view of...

I don't know if it is appropriate to post this or not...so if it isn't, please go ahead and delete...BUT, my friend is considering purchasing a new pool and has researched the following on this website: http://www.poolproducts.com/SPP/dept.as ... 266&FNM=94 What is your overall impression of...

I live in South Arkansas and we're getting 85-92 degree sunny days right now. My 17,500 gallon fiberglass pool has a CYA of 50. What is a reasonable daily FC loss? I'm losing around 3ppm a day and that seems excessive to me. What do you think? Thanks, Alan

I just completed shocking and my FC is holding overnight. Below are my most recent test results. I think they all look good except for the fact that I'm questioning my TA after reading pool school. What do you think? FC 10 CC .5 TC 10.5 pH 7.5 CH 250 TA 120 CYA 50 Thanks, Alan...

Can anyone venture a guess as to what these spots may be? I realize the clarity of the picture isn't great, but it was the best that I could do today. They are darkish-brown in color and will not brush up with a regular pool brush. They are both in the shallow end and deep end of the pool...

When is the latest possible time you can test in the morning? A couple of minutes before "official sunrise?" I'm not an early riser and prefer to put it off as late as possible. Thanks, Alan

The overnight free chlorine test at high levels of chlorine (16ppm-19ppm) is starting to baffle me. For the last 3-4 days, in my unprofessional estimation, my pool has looked great. However, I still can't get the overnight free chlorine test to show absolutely no loss in chlorine. Last night...

For the purposes of the Overnight FC Loss Test, does a cloudy day (no appearance of the sun) work as well as a night? In other words, can I essentially do the test in the day instead of night if it's cloudy outside? Thanks, Alan

I have a sand filter and my pressure gauge is currently broken. I thought about running to the pool store and buying a new gauge. What pressure reading typically means it's time to backwash? In the past, I've just backwashed once a week and I'm sure that's not the most effecient way to do it...

I started the BBB method halfway through the swimming season last year. I'm ready to open my pool for the first time using the methods utilized with this system. Do I need to go ahead and raise my CYA to mid-summer levels (40 or 50) and then shock until there is no overnight free chlorine...

I have a 17,500 gallon inground fiberglass pool. I just purchased a 32 oz. bottle of 60% Poly {oxyethylene (dimethyliminio) ethylene (dimethyliminio) ethylene dichloride}. How much should I use as I prepare to close the pool? The whole bottle? Thanks, Alan 17,500 gallon Inground Fiberglass...

I just retested my CYA this morning and is 50...which means I need to keep my chlorine level between 4 and 8. If I let my chlorine level fall to 1 or 2, is that the equivalent of letting it fall to 0 with little or no CYA? I guess what I'm wondering is there a danger for algae at the 1 or 2...

Here are the details: South Arkansas 97-100 Degrees Not much shade 17,500 Gallon Fiberglass Inground Pool CYA of 40 What would you expect the daily FC loss to be assuming no organics and no swimmers? Is losing 3ppm per day way too much or possible and even probable during times of intense...

I'm just curious and would like a range of opinions as to when you typically shock? Do you always shock after a heavy swim load or decent storm? Or do you rarely shock and just monitor your daily FC loss, and if it stays consistent you don't worry about it. Just curious? Thanks, Alan

I'm leaving town for a few days and have no one to monitor the pool while I'm gone. What do most of you do in this situation...keep in mind that I have no tablets. Do you typically go and buy a small bucket of tablets and put a few in the chlorinator while you're gone, or do you get your...

I would like to have someone sand all the imperfections and paint my pool an entirely different color. Are these types of contractors tough to find? Are there any national contractors that do this all over the country for a reasonable price? What type of $$ should I expect? Thanks, Alan...

Test Results: FC 6.5 CC 0 TC 6.5 ph 7.5 TA 120 CH 260 CYA 20 I think I've got a problem? One month ago I had a CYA reading of 50. Today I had a CYA reading of 20...both readings were from the the TF-100 test kit. We are probably putting in about 1-2 inches of new water every other day due to...

Readings As of Yesterday: FC 5 TA 100 CH 260 CYA 46 pH 7.7 I live in South Arkansas and we've been averaging 95-100 temp. over the last couple of weeks. I'll have anywhere from 2-6 people swimming in my pool daily. Most of the time just 2 adults and 2-3 very small children. I have very...

My polaris is powered by one of my return jets. In order to get the optimal pressure to run the polaris, I have to put in an eyeball fitting with a very small opening in the other return jet. Do you think it would be OK if I left that particular eyeball fitting in my jet permanently? It's...

Why does a tablet without acid not exist? From what I've read in Pool School and in these forums, the major drawback of the "pucks" is the acid they continually add to the pool. I hate that I have a an automatic feeder that I'm not using. Or maybe they do exist, and there is another reason...

Is this normal...I'm guessing it's evaporation, but it could be a very slow leak? Am I maintaining my CYA levels if I'm adding approx. 1/2 inch of water every day (17,500 gallons)? If I'm not, it might be wise to go ahead and use my tablets throughout the swim season. Just curious what you...

I've decided against using my tablets and Turbo Shock for this swim season and am ready to fully convert to Trouble Free methods. Here are my current readings: FC 16 CC 0 TC 16 pH 7.5 TA 150 CH 280 CYA 34 I know my FC will fall over the next few days to normal levels...any other urgent...

This morning I did 4 consecutive tests and got the following readings: 16.5, 15, 20, 19. Do any of you have a way of making this test more accurate? In my opinion, the size of the scoop and the dissolving rate of the powder have to be the variable that causes my readings to vary somewhat...

I have several rusty-brown looking stains near my main drain. I know a couple of them were caused by some metal pieces that fell in the pool when it was green...and I couldn't find them. Any ideas on how to clear them up? Thanks, Alan IG Fiberglass Sand Filter 17,500 gallons

3.5 lbs of CYA finished dissolving in my skimmer yesterday evening. What's the likelihood that I could get an accurate reading if I took a water sample to the pool store this morning? Thanks, Alan
