    Need to Backwash Prior to Replacing DE Grids?

    Title says it all :) I purchased a new set of grids and wondering whether I need to backwash before taking out the old ones and and replacing them. I guess backwashing might make the grids a little lighter, but could I instead just hose the old grids off instead? Just looking to avoid...

    R-0013 (CYA Reagent) Expiration Date

    I'm out of the three 2-oz bottles of CYA reagent that came with my K-2006C test kit. So I ordered an 8-oz refill bottle from However there was no expiration date on the refill bottle, but my original reagents in the 2-oz bottles had an expiration date. Should I be concerned...

    Daily Chlorine Usage and FC/CYA Chart

    Hi, It's been about a month since I ditched tablets and pool store testing and began my own TFP-style maintenance. I have a few question about FC levels for which I search around and couldn't quite find. My CYA is 50 (no SWCG, at least yet). According the FC/CYA chart I should be at 6-8 ppm...

    Idea For A Skimmer Basket? Or maybe it already exists?

    As I was cleaning the rough/mesh/screen filters for my Dolphin S200 this morning, I noticed how much debris they trap and how easy they are to clean - just hose them off for a few seconds and you're done. Since I use a hairnet to trap finer debris in my skimmer basket, it got me to thinking...

    Sample Size for FAS-DPD test

    Purchased the Taylor K-2006C recently and having been using the 25 ml sample quantity for testing FC and CC. Since the 25 ml sample requires more drops of R-0871 to determine FC, are there any downsides to using the smaller 10 ml size? Improved accuracy?

    Free Chlorine and CYA: Couple of Questions

    Hi, 1) I always understood (maybe incorrectly) that a proper level of chlorine in a non-SWG pool was 3-5 ppm. At least that's what Leslie's told me and what they tested against. In looking at the Chlorine/CYA Chart, it shows 3-5 ppm corresponds to a CYA level of 20, which is below what is...

    First Test w/New K-2006C

    Well, I've relied on Leslie's water tests (mainly for CYA and CH) and my own Cl and pH testing using Taylor's OTO kit. Seemed to have gotten me by all these years, but because of quarantining and wanting to take more control of my pool testing I decided to take the plunge. Not sure if I am...

    Best time to Test Water

    Just received my first ever K-2006C test kit, with magnetic stirrer. I'll post results once I figure out how to use it, but for now, when is the proper time to test my water? Any time of day better than others? Does it matter if the pump is running? Thanks!

    Can you leave a Robotic Cleaner in the pool?

    Can the Dolphin cleaners be left in the pool all the time without risk to the cleaner? Being retired, I'll occasionally be gone on vacation 2-3 weeks. I wouldn't want to pull the robot out before going.

    Why a Robot?

    I'm in the same boat as the OP. Loved my Poolvergnuegen (aka The PoolCleaner) but it's having some trouble. Took it apart and had a look but to no avail. I just don't know if I want to deal with having to continually take a robot out of the pool and put it back in. How often do i do that...

    Robotic Cleaners and Skimmers

    Hi, I have always owned suction-side cleaners; my current one is a pre-Hayward PoolCleaner, about 6 years old that I really like. It's having some problems now (not moving) so I'm considering a robot cleaner. I understand that the robots don't require the pool pump to be on in order to...

    Hi from Long-Time AZ Pool Owner, New to TFP

    Hi, I stumbled across TFP after a google search. I see that TFP is a great resource for pool owners such as myself who are mainly DIY owners! However I'm now in a quandry over whether to adopt a new maintenance regime. I currently use 3" tabs in a floating device in order to sanitize my pool...
