So, I was at a local large chain business hotel ("CY") working out in the gym this morning....pool is right in front of me through the windows. In walks the maintenance guy with a couple small taylor bottles with yellow and red caps and a test block from a k-2005 kit. He kneels over to get...

I just got mine too...I picked up the DPD basic kit for daily testing. What's funny is that they have a distribution center about 3 miles from my house, but they still needed to FEDEX it

the overnight FC loss is a good idea....didn't think of that (though I should have....no different that what you want to do if shocking). Since I'm around this weekend, I'll give it a shot. I also just adjusted my pump schedule to go 2.5 hours in the AM and then 9.5 hours in the PM (until...

Jason - yep...exactly why i'm asking...I don't quite understand why I appear to be using so much FC. My CC's have consistently been ZERO since opening the pool in April. With the high temperatures we have been having, the kids have been in the pool pretty constantly. My PH seems to float...

I was just thinking about this same issue this morning. I was away for the last couple days and had my wife checking the CL levels. We have had VERY sunny days for the last week and I can't seem to keep a FC level above 2. My CYA level is about 40 and I am using a LQ with 12.5% chlorine. I...

well, the pool is right out in the open and we get beat on from 10 - 11am on in the summer. So, it's sounding to me that the 8 gallon liquidator would make more sense so that I can get at least a week before refilling

With a CYA level of approximately 50 in a 28,000 gallon pool, how much chlorine should I expect to burn each day (assuming nothing is consuming the chlorine levels) ? I'm currently running Trichlor but am looking to switch to the Liquidator. Based on some other posts I have read, it seems like...

These all sound like great ideas.... Here's another idea, though it's not necessarily so much of an improvement to the TF-100. Rather, it's more of and idea for an extension to Jason's Pool Calculator. These days, many of us have portable web devices such as the dreaded Blackberry. While...

thanks guys....i'll let the FC come down to normal range and check again in a day or two.

Before shocking the pool with 12.5% liquid chlorine, I had the following numbers: FC .5 CC 1 PH 7.2 TA 70 CH 210 CYA 40 I put in enough chlorine to take the FC level to 15, based on Jason's Poolcalculator. This morning, my levels are: FC 15 CC 0 PH 8 <<-- This is where...

Mbar - to clarify, should I be concerned with getting total chlorine to 6-8ppm or free chlorine to that level? As for algae, I don't think I have a problem...water is clear, but did notice a couple dark marks on the deep end wall this morning that I don't recall seeing before.

I shocked on Sunday night with 6.75 gallons of 6% bleach which should have brought my FC to about 16. My numbers before shocking were: FC 0 TC 0 pH 7.4 Alk 100 CH 250 CYA 45-50 I puposely brought the Cl levels down to do an acid treatment on a suspected stain. I...

As a follow up, I also noticed some black marks on the bottom in the deep end. They look like small scape marks and are not round (as I suspect would be the case if it is black algae...though since I'm new to this, I don't know. If I try the trichlor tablet approach to removing a stain, how...

So, I now have a test kit (Taylor DPD Complete). I shocked on Friday night with 8 gallons of 6% bleach. FC and TC came in at about 15. As of tonight, I'm getting FC and TC of about 6 (we had a beautiful cloud-free day today). Here's the rest of my numbers based on my own testing: FC = 6 TC...
