testing what?

This site wouldn't let me reply but I've figured it out. Will recompose my questions.

WaterMom, great suggestion!!!

Already I have a question. Arg! Thought I'd have my K2006 out already...but:

The pool guys told me that they are not installing my new pump until Thursday or Friday so my new water will sit until then. I told them that I was nervous about that because I am leaving town on Friday and won't return until Monday morning and that I didn't want to come home to a green pool! They told me not to worry because they include start-up chemicals when they do a new liner and water..... Surprise!
They use BioGuard products and my best guess as to what they will use are:
1.) Super Soluble, Burn Out 3, or Burn Out 35 for chlorine
2.) Pool Magnet for metals
3.) Algae All 60

Should I tell them no? Should I say yes to some and not to others?

In a panic here....See post above for details. My new water is looking bad. It is brown-tinted from what I think is iron. The water is all well water either from my hose (with MetalTrap attached) or from municipal wells. I have researched the Metals forum and can't seem to find answers. I know the pool guys will dump a ton of Pool Magnet into it tomorrow if I don't tell them no.

Don't Panic!

Do the Bucket test for metals to verify metal in the water. What does the inside of the toilet tank look like?

Bioguard's Metal Magnet Plus is (according to MSDS) 36% HEDP and 1.8% Phosphorous acid. HEDP is a recommended sequestrant and should help get metal in suspension. I'd let 'em put it, hopefully it will clear the water.

You may want to put trichlor tabs in the skimmer - couple reasons. 1) You need chlorine and CYA in the new water. 2) The tabs dissolving in the skimmer will raise chlorine and lower pH in the water before the filter encouraging the metals to drop out of suspension onto the filter. You can do this because you have a sand filter and run the pump 24/7. If you do choose this startup, don't let them put the dichlor (Super Soluble) in the pool.

It may also be a bad idea to put a lot of chlorine (Burn Outs) in the pool if there are metals in the water - it could cause metal staining on your new liner.

The Algae All 60 is Polyquat 60% (from MSDS) which is the only algaecide recommended here. It will help keep algae from getting a foothold while you're starting up. Especially a low chlorine start you'll need if you do have metals.

Please consider any warranty requirements before deviating from their plan.

Take a full set of readings (except CYA) on your new fill water and let us know.

Congrats on the new liner - Good Luck.

@BigDave: Thanks!

@BromineUser:

1. Do not chlorinate.
2. Do use HEPD *AND* polyquat. There's nothing special about BioGuard chemicals, except the labels & pricing. Check these at Amazon if you need more.

Kem-Tek 311-6 Pool and Spa 60-Percent Concentrated Algaecide, 1 Quart
Jacks Magic The Pink Stuff 1qt (60% HEDP)

3. Keep the pH below 7.6
4. Brush daily; operate the filter 24/7.

What kind of filter do you have? If a sand filter, get a bag of DE powder, and add 2 cups of DE daily to the skimmer. Watch your pressure and backwash on a 5 psi increase. Do NOT add DE to a cartridge filter!
