What caused my new pool water to turn green?

No- stick with the skimmer baskets only.
You don’t want it to accidentally end up in your plumbing, filter internals, or pump impellers.
Change it out/wash it out as it accumulates the iron.
There are 6 wall drains as well as the main drain in the bottom. The 2 skimmers don't pull much water.

There's not a way to fill the actual pool filter with the polyfill?

Adjust your valves so you are pulling more water through the skimmers.
Show a pic of all your valves & equipment for guidance on how to accomplish that.

Ah, OK.

The water is clearer this morning but of course it has stained the grout on my tile spillover and around the white plaster edges.

Best way to clean that? Something I can add to the water to clean it our do I have to go all around the pool to each area and spot clean?

Will this stuff work?
 
Your fc level may be dropping & allowing the iron to “hide”.
Is your swg running? (If you’re not more than 30 days out from new plaster it’s not supposed to be)
If not you need to add 5ppm worth of liquid chlorine (pool chlorinating liquid) to the pool daily to keep things from getting funky until you’re kit comes & you have accurate data
- buy that instead of potions 🧪
Let’s get the iron out of the water before dealing with stains.

I see I can cut the flow totally from the main drain so it's only coming from the two skimmers. Is that what I should do?

Water is a lot clearer so now worried about the stains getting worse.

What are you going to do with that? dump it in your pool water?

Do you know what is in it? Do you know what it will do?

At TFP we don't look for magic potions and we don't add anything to the pool water without knowing the ingredients and what it will do.

This product contains 10% 2-phosphonobutane-1,2,4-tricarboxylic acid. See the attached MSDS.


2-Phosphonobutane-1,2,4-tricarboxylic acid Chemical Properties,Uses,Production​



Description​


2-Phosphonobutane-1,2,4-tricarboxylic acid(PBTC) is the latest generation of internationally popular phosphine carboxylic acid, and it is one of the most widely used and best-performing products in the compounding of high-efficiency scale and corrosion inhibitors. It is especially suitable for water quality conditions of high temperature, high hardness, high alkalinity, high pH, and high concentration ratio, and has good scale inhibition performance for calcium carbonate scale and calcium phosphate scale.

Uses​


PBTC is the most widely used in the compounding of high-efficiency scale and corrosion inhibitors, is one of the products with the best performance, and is also an excellent stabilizer for zinc salts. It is widely used in the corrosion and scale inhibition of circulating cooling water system and oilfield water injection system, especially suitable for compounding with zinc salt and copolymer. It can be used as a chelating agent and metal cleaning agent in the washing industry.

Chemical Properties​


2-Phosphonobutane-1,2,4-tricarboxylic acid (PBTC)is colorless or light yellow transparent liquid. Relative density (20°C) 1.275. Freezing point -15°C. Has excellent scale and corrosion inhibition properties. Acid resistance, alkali resistance, oxidant resistance. When pH>14, it still does not hydrolyze, and the thermal stability is good.

What does the polyfill look like?

It was 50% brown. The pool guys put a bottle of metal free in it when they were here 2 days ago.

Iron stains all along the water line tile grout, sides of the plaster, and tile grout on the spillover. Wife is upset so that's why I'm trying to understand the solution, even if I don't tackle it until I get the water balanced.

Use ascorbic acid or crushed up vitamin C on the brown stained areas. Put it in a sock and rub it on the stains.

You don’t have to totally cut off the main drain just reduce it so there’s sufficient flow to the skimmers.

I appreciate that but I'm trying to understand what can be done. I'm looking for solutions. I don't especially care right now if it comes from a bottle.

I paid $100k plus for a pool that now has stains all in it that I don't want to get worse. If it's not going to get worse, great, but in still trying to learn.

I did that on a smaller area last week. After 15minutes of scrubbing it made it less noticeable but still there. The area was maybe 4x4inches.

These stains are everywhere on 1,000sf pool. Is there not a faster way? I'll do it if it's the best way, it's just going to take days if not weeks. Again, if some other method is going to be permanently detrimental to the pool, of course I don't want to do that.

With the amount of money I've spent, I'm ok if it costs more to do it another way.
 
The quickest way to ruin your $100K investment is to dump unknown chemicals into your pool while your plaster is curing.

We are trying to advise you not to do that.

There is a full AA treatment of the pool. But that will not get the tile and grout above the waterline.

And an AA treatment should not be done on a new pool. Wait at least 60 days.

At this point what is done is done with your staining. Spot treat with vitamin C and see how far you get.

Be patient and let your plaster and grout go through the chemical curing process. Any harsh treatment is more likely to cause long term damage to the pool.

Which I appreciate. I read the ascorbic acid page. I'll do that later since it sounds like it will be ok to wait.
