ok - thanks to both! i'm hoping it's just days more rather than weeks. during this time, i need to keep the filter running 24/7, correct? And, the water has been clear; I can see to the bottom. the only visible green was adhering to the sides of the pool surface in a few small patches; and...

Update - yesterday evening, I added bleach based on required amount from pool math; two hours later (9pm), my FC was 20 (i felt pretty good because this was the first time there wasn't a drop in FC in 2 hours; earlier that day it dropped anywhere from 1-3 ppm every 2 hours). This morning (SLAM...

My ph was 7.6 when I started the SLAM. This will be day 3; when I checked my FC last evening it was 10 so I added more bleach to the recommended FC shock level. - - - Updated - - - I saw my signature dropped off again so trying to add it here

Thank you for the reply And I'm not sure why my signature dropped off? It's still seen under my profile. I thought during SLAM ph levels are impacted so not to check them. I'll do that. the FC has been below shock level

Hello! my backyard has an odor of chlorine now. I assume that's normal during the SLAM process? And others have said it's safe for us to swim during this process, just want to confirm that? Thank you

thanks to both of you! this morning my FC is only 9.5 so i will continue to SLAM. I was reading on TFPs site about the different types of algae and i'm very concerned I may have the mustard algae. how would i know for sure? it looks like all of this will be for nothing if it is mustard algae...

Update - I've poured a lot of 96 oz jugs of chlorine (bleach) into the pool today based on pool math's direction. Before i began the SLAM process, my CYA was 50 which indicates a FC Shock level of 20 is needed. After the 1st hour, i adjusted my pool volume (pool math calculator) slightly based...

thanks again!

i have another question; on testing for FC and CC. The test instructions indicate to apply drops until it turns clear. is this the 1st time it turns clear or need to keep adding drops until it remains clear. i notice when i remove from the speed stir and it sets for a little while (seconds to...

ok - thank you!

I want to make sure all my information is correct in the pool math calculator so i re-measured my pool. it looks like i have more galloons than i was originally told. it is an oval, free form (irregular) shaped pull. at the widest it's approximately 14 ft and at the longest it's approximately...

Hello again I received my TF100 kit in the mail! My FC is .5 and CC is .5; making my TC 1.0. My CYA was near 50. My TA is 90. My ph is 7.6. i'm going to plug my #s in and begin the SLAM process; hoping to get things resolved now! thanks for any thoughts or suggestions!

thank you!

thanks again to everyone that has responded! is there any concern for skin or swimwear with FC levels so high? i was under the impression residential pools shouldn't have FC levels much higher than 4 ppm. it sounds like by using liquid bleach my levels may and need to be 6 or higher for...

thanks to all that responded; i will get the test kit ordered and begin using liquid bleach! I will post back once I know where I'm at with the new test kit. And, I have been reading some of the pool school info. It sounds like I will need to "SLAM" but can't do that until I have one of those...

Hello, A little background first - we purchased the home in April 2016; the pool was only 1 yr old (installed Summer 2015). It had a high (100+) CYA level. It took a full year to get the CYA level below 80. Most recently, the local pool store has reported our CYA readings as low as 30 (late...
