I read through the DE filter cleaning tutorial "stickied"at the top of this forum section and probably learned what I have been doing wrong, even though my filter is the bump style not covered by the tutorial. Thank you for a great tutorial. My issues had been that after backfushing I could...

Installed my pool filter for spring startup, as I have for the last 30 years, but this year I can't get any pressure out of it. The pump/filter that I am using now is only a few years old. System was working fine when put away last fall, cleaned the fingers and grid. The pump/filter operates and...

I am not new to this forum or the BBB method, been here and using it since 2008. I just wanted to give a shout out to all those that make this site possible. The amount of knowledge and help I have received here is irreplaceable! I have been blessed to find this site. I am surprised that my pool...

I currently have a Hayward DE filter with a 1 hp Super Pump wired for 110 volts. The motor is bad and needs replaced. I have found a good deal on a new complete Super Pump with two speed motor. My question is this, are two speed motors 230 volt only or can they be switched over to 110 volts as...

First I want to say thank you TFP, since switching, last year, to the BBB method and using the TF-100 test kit my pool has truely been trouble free! I do have a question on testing the TA with the TF-100. I get a distinct color change at 7 drops but it seems to be more purple than red. The 8th...

When running most tests, with most test kits, the instructions tell you to swirl after adding each drop. How important is that? For example, if testing FC and you know that it is approximately 10 ppm. Will it make a difference, in your results, if you add 10 drops then swirl, add 6 drops then...

This past weekend I had a couple of people over, everyone including me could smell the chlorine in the pool. Just a faint smell, but a smell none the less. I'm using liquid bleach to sanitize and my CC has remained consistently < 0.5. I'm using the TF-100 to test. Should you be able to smell...

Background: After 20 years of owning my pool and encountering many problems I am now just learning about pool chemistry through this site. I ordered and received a TF-100 test kit and love it. While waiting for the TF-100 to arrive I noticed that the top step of my pool ladder had turned pink...

Received my TF-100 today and am very pleased. My first test results are as follows: PH: 7.3 - 7.4 (still a little hard for me to distinguish the colors, but more pink than orange) FC: 3 CC: <0.5 (but there is some!) TA: 90 CH: 170 CYA: 60-70 (closer to 60, I think) I know at my CYA level I...

I read in "Pool School" under "recommended levels" that for vinyl pools the TA should be 70-90ppm, unless using Trichlor tablets for chlorine, then don't let it fall below 100ppm. I am currently using Trichlor but am planning to switch to liquid chlorine, my TA is currently 70. Why the...

Trying to decide which kit to get. My concerns are as follows: 1. I have trouble color matching both the OTO and PH in a standard drop type test kit. The taylor appears, from the pictures, to have a fairly nice PH test block, I'm concerned the TF-100 may be the standard test block found in most...
