Does anyone have any figures for safe FC levels for swimming? Sources??

I have had my pool a couple of years now, but I am still concerned with what I think is excessive acid usage. Every 3-4 days I need to add between 400-800ml of muriatic acid. My chems tonight are: Chlorine 2-4 pH 7.8 Total Alk 70 Cal Hardness 300 This is 4 days...

The pool store guy that sometimes test my water claims that he stops after the color change on some tests brightens, whereas when I test I stop at the first permanent change of color. What do you think is correct? The difference in my case was a total alk of 80 when I tested and he got 105, not...

well after 1 year of use the brush I had gotten with my pool has started to lose its bristles. Actually the bristles have become brittle and are snapping off making a mess of my sparkling clean pool :O Does anyone have advice on a good brush? Should they last longer than 1 year? Any makes to...

Does anyone have a picture of the color comparator that comes with the TF100 kit? I would like to see it before ordering. I am having a little trouble with my current block b/c the 2 colors that I try to stay between are too similar in color. Thanks!

Ok, now this is bizarre: Chlorine 3.0+ pH 7.6-8.0 (fluctuates upto 8.0 every 3-4 days - usually about 1-2 cups acid brings it back down to 7.4-7.6) TA 70 CYA 30-40 CH 350 I have had some minor staining issues since the pool was built in late june. The PB came and took care of them in early...

Forgot to ask this in my other post: How often should one test and is there such a time when you "learn" your pool's chemistry needs and are able to reliable add xx oz. of Cl, etc. on a daily or semi daily basis? If the pool is clear and pH is on target is it ok to allow Cl to fall to 1 before...

Ok, as part of my warranty from P-Tec I need to get monthly "professional water tests with computer printouts". I found this to be a farce. I just wanted to know if anyone else has come across this? Can't I just produce my own computer printouts? I have taken my results and then brought them to...

Hello all, I was reading an interesting article on CYA. I have been watching my level go up now for the last several weeks. I was concerned because trichlor pucks are the main cl source for my pool and I know that once its in, its there for good! I especially liked the author pointing out the...

Hello all, I have a 4x160 pump and wanted to know if this was a good way to go about finding flow rate. I used my pump to draw water from the pool and used the drain valve with hose to fill up a 5 gallon bucket. I checked to see how long it would take on the first 3 speeds. The thing i was...

Ok! I have my first sets of pool chem: My question is at the last set of results/ At startup: TC 1.5 pH 6.8 Alk 50 next day TC 0.3 pH 6.8 Alk 40 Went to pool store and bought Calcium hardness additive, chlorine, Cl tabs, borax (for future), stabilizer and additional test kits (cal hardness...

Any advice on handrails? I am looking to add one on perhaps later. I was looking for any info on flange type that can be tapcon'ed into bond beam. And yes, I will have to stub now for grounding :) Thanks!

Hello all, wanted to know how you would go about fixing pipes or altering your plumbing system if its been painted. Do you simply sandpaper down to pvc? Any ideas? Just wanted to know so that in the future after finishing the build, I'll know whether or not to paint. Thanks My Pool Build

Ok all, this question has been bugging me.... In coastal environments, condo's that are of steel reinforced design have occasional issues with rebar rot. The rebar rusts deep inside the concrete, usually on the balconies and at the balcony to building joints. In severe cases the concrete around...

Well the hard stuff is done (finding someone trustworthy to do the job). The plans - basically a square shaped pool to maximize the use of our yard/pool space. Pool to be 3.5-5.5' deep, pebble sheen interior with paver deck and screen enclosure. The yard before we cleared out all the palms...

Hello all, yet another question or two: When plumbing suction, I have read somewhere that you need to plumb them in a ring so that all suctions are feeding off the same line such that there is no difference in pressure. Does this also apply to returns? On a 12-15k gallon pool is adding a floor...

Hello all, I am new to the pool forum and to entertaining thoughts of having a pool built. Hence the name, newfool. Spending much money to dig a hole in the backyard :P I would love any and all advice as well as your thoughts on: 1. In floor cleaners 2. variable speed vs. 2 speed vs. single...
