We bought our pool last Wednesday. Simple small pool. In our back yard which is large we only have a small area that we are able to place the pool due to our septic and power lines. We went with a Pro Series Ultra Frame Metal Pool that is a 15x42. Fun for the kids was our aim.
We leveled the ground on Friday and set up the pool. Add about 2 inches of water to the bottom to straighten the liner. All water is coming from our well.
We bought HTH product line. The 4 steps, Alge control, and shock and swim all HTH brand. Read everything and at this time "think we know what we should be doing"
The Algecide said to add some during the fill, for opening a pool. We did at about the half way point of the water.
Started to fill it the rest of the way. Continued filling through Saturday. As the pool reached about half way we notice it was a light green color. By Sunday mid morning the pool was filled to the skimmer. It is a side wall filter skimmer with a cartridge. We turned the pump on.
We tested and CL was 0 PH was 7.4 We added the Shock thinking that would clean up the green. Ran the pump and the green got darker to where I could no longer see the bottom. We then added claifier thinking that would "clean it up". Nope. So I came here and started reading and reading.
Tested again and Cl was about 4 and PH was still at 7.4 We just have a tester that test CL, BR, and PH.
After reading, I learned that it was probably the metals in my well water making the "green". So we ran to Walmart and bought HTH Metal. We added 16 oz late last night and ran the pump continually. Cleaned the filter before bed, again and 5 am, and again at 10 am this morning. The filters were a nasty orange color and very dirty. At 11 I replaced the cartridge and added more HTH Metal and let the pump run until about 1pm. I tested again and same results CL 4 and PH 7.4. At this point I could see the tile design on the liner, but the water was still green almost a green/turquoise color.
I decided that I would call a pool company and see if they could test my water for me. I took some in and the ALK was above 240 all other numers were the same as my last test above.
They said that I need to get the ALK in check and to use 1/2 gallon of MA. Come home turn off pump and poor it in let is sit for a few hours and then turn on pump again. I also bought a strip test kit that checks CL, ALK, PH, and CYA. I checked the water before adding the acid. It tested CL 4, ALK 240, PH 7.2, CYA about 60.
I waited about 3 hours and started running the pump, water stayed about the same, I could see the tile pattern across the pool but still greeny/turquoise.
I have now ran the pump for about 4 hours and retested. CL O, PH about 6.8, ALK still about 240, CYA O. I began reading again. What I read is that PH needs to stay in check and the using MA will decrease the PH, to bring back the PH with out using chemicals that will up the ALK at the same time I need to arerate. I turned the water output to just skim the water surface to begin this process in hopes it will bring the PH back to 7.4 with out chemicals.
The pool place seemed to think that my water is the way it is because of the out of control ALK.
So after all of that long winded story.
Here is where I am.
I have 0 CL, 0 CYA, PH last check was about 6.8 and ALK 240. My pump is still running. I just now went out and took out the filter still nice and orange cleaned it and replaced it. I have not added anything else am and letting the pump run through out the night.
So do I now add more HTH Metal? More MA? What is my next step come morning? Add more shock? CL?
Is the color of the water simply because of the well water/metal in my water? Is it because of the ALK being out of wack?
The water is better as of today (day 2 of being filled). But still greeny/turquoise. Now now CL or CYA in pool, PH is low, and ALK is High. Pumping is running and filter being cleaned and is alway orange each cleaning. Aerarating through out the night with the water output skimming the water surface in hopes of bringin PH up with out the use of chemicals that would up the ALK.
Any input, suggestions, comments are welcome!
