What are the best alternatives to restore a 20 year old fiberglass pool?

Tested Pool 90 days ago (drop test)and combined chlorine was.5 which has been normal forever. Tested today 3 times (drop test) and each time the pink color got lighter after the first (or 2d) drop but stayed the "lighter" pink without changing to clear after as many as 20 drops of R-0003. Bad...

Will aerating during SLAM help to keep my TA down?

I plan on using the "AA" process with Jack's Magic Stain Solution 1 and Jack's Magic The Pink Stuff as the sequestrant agent. I have identified the stain in my in ground fiberglass pool as an iron stain. Question: Has anyone had experience with the products mentioned being used in a fiberglass...

In ground fiberglass Spa developed a leak where the Spa light inserts into the shell. Water drops to half way down the light then stops which eliminates all other possibilities of the leak source (jets and water input above the light ... drain plus two other jet items below light). No cracks in...

I have 2 small brown rust stains on the floor of my in-ground fiberglass pool. How do I get rid of them without draining my pool or destroying the gel?

I have a spill over fiberglass Spa. It is filled by pool water. A light green stain has developed all around the side of the bottom half of the wall section just above the Spa floor. The rest of the inside of the Spa looks great ... no stains anywhere ... to include the top half of the same...

OK ... I've read all about closing a IG gunite pool and am still confused. This 15x30 IG gunite pool (my daughter's) will not really be "closed;" it simply will not be usedf for 6 months due to maxium low water temp in Yuma (mid-40s night - daytime temp 70+). Here is my plan: 1. Clean 2...

My Pool Service (recently srarted) has a SGS Instruments SLDT Salinity/Conductivity/TDS meter that is NSF international certified and by which he swears by for accuracy. I have tried all manner of tests for salt and finally stayed with the strip test which I have been using for over two years...

I have ... (wife dictates) ... to keep my heated pool water temperature at an average of 88 degrees. That means the temperature flucuates between a high of 90 degrees and low of 86 degrees. Do these temperatures have any effect on the accuracy of my water test results?

I am replacing the sand in my sand filter as sand from the filter is "leaking" back into my in-ground fiberglass pool. I wiil replace the laterals as I am told a broken or split lateral is the only way the "sand leak" could occur. While this explanation for my problem does make sense to me I am...

I have a 14,800 gallon fiberglass inground pool with a Spa overflow and a SWG. The water in the Pool is SOFTWATER (water for pool goes through my home softwater system) which requires me to add a calicum hardness increaser every 90 days to maintain a 200-220 calicum level. TFP recommends the...

I will be leaving for vacation during our "monsoon" season ... in Yuma, AZ "monsoon" equates to wind. The neighbor that usually checks my pool for me is going on vacation also during this time. The wind during the "monsoon" season results in many leaves. etc., in my pool, filling the skimmer...

The topic is Calcium Hardness. My current CH level in my inground fiberglass pool with a SWG is 180. I raised it to 180 after conflicting recommendations from several sources that resulted in my decision to keep it above 150 by maintaining a 180 level. All other measurements are at TFP's...

I live in Yuma, AZ. Nighttime temperture lows are between 40-50. What do I to "close" a pool that really just sits inactive during Nov-Mar (5 months) as it is not heated.

The instructions for my new and not yet used Apollo Magnetic Stirrer state "turn the speed control knob clockwise until the desired stirring speed is attained." OK ... what is the "desired stirring speed"??

When using the Lamotte Color Q my TA was in the 63-80 range which I thought was good. The TF100 TA test has tested once at 150 and today at 160. I am convinced that the TF 100 TA test is correct. My water is crystal clear and the results of todays test follow: FC-5 CC-.5(-) TC-5.5(-) pH-7.7...

The only dumb question is one that is not asked. Therefore ... the following: The same chemicals are used in the Lamotte "black dot" CYA test and my brand new TF100 test kit. However the instructions to mix are different. Lamotte "black dot" CYA test says to shake the mixing vial for 1 minute...

Hi, I am a 4 year pool owner and after much research have decided to join this forum, and only this forum, as TFP clearly is the only swimming pool site with no hidden agenda. In other words, answers instead of sales. I am trying the approach of higher chlorine levels of 3-5 (vs 1-3) and higher...
