Testing & treating pool fill water

[PoolDoc]

Orange brown = iron

Just to clarify: you will be filling the pool with the same water that's going into your toilets?

Yes, sorry I didn't say that before, I will be filling the pool with my house water.

Also, there were orange stains on the pool stairs. I rubbed them off with a cut lemon after reading they might be metal stains.

Thank you again.

Taylor kit arrived today. Results are:

FC .4 ppm
CC 0.0 ppm
pH 7.8
TA 20 ppm
CH 20 ppm

Filling a pool with water containing iron can be tricky, if you want to avoid stains.

You may want to order several quarts of polyquat, and a quart of HEDP. The polyquat will allow you to avoid algae, without precipitating iron, and the HEDP will help keep the iron IN the water (instead of ON the pool) till you can begin filtering.

Once the pool is full and the filter is operating normally, you'll want to lower pH levels gradually to around 7.0. Then you'll need to raise your total alkalinity to at least 80 ppm, by dosing with baking soda, 3 lbs at a time. The pH will rise; if it gets above 7.6, add acid to lower it to 7.2 before adding more baking soda. You can also add stabilizer during this time.

Once the TA is 80 - 100 ppm, with the pH around 7.4, you can begin gradually raising chlorine levels.

Tell us how you intend to chlorinate, and we can tell you how much stabilizer to add.

Here are links for the HEDP and polyquat:

The new liner is being delivered Tuesday. They will probably come start draining the pool tomorrow. Today I'm painting the aluminum coping. I've ordered the polyquat and HEDP and some stabilizer.

I am planning on learning to use the BBB method this summer. I still have a box of shock and a bucket of trichlor tabs. We have an inline chlorinator. I also have a few gallons of Costco chlorine that I use for many things around the house, but can use it to chlorinate the pool.

I imagine that I will keep using the inline chlorinator this summer, but I won't shock on a regular basis. Shall I use the shock as startup chlorine for the pool? I'll mix it with water in a 5 gal bucket before adding it to the pool.

How does the type of chlorine affect the amount of stabilizer? Either way, I'm up for good advice on chlorinating and stabilizing Thank you!

[PoolDoc]

Look on the label of the "shock" you have find the % chlorine, and the % of all listed ingredients, and tell us what they are.

Trichlor (usually 3" tabs, but sometimes other forms) and dichlor (always coarse granules) add 1/2 ppm or more of stabilizer for each ppm of chlorine added.

Both the shock and the tabs are Pool Brand from Sam's,

The shock has 99% Sodium Dichloro-s-Triazinetrione, and 1% other ingredients. Available Chlorine 55.5%
The tabs have 99% Trichloro-s-Triazinetrione, and 1% other ingredients. Available Chlorine 99%
