I am converted. After reading the forum I have gone to the BBB system. I bought a TF test kit. Last summer I had terrible algae problems and spent beaucoup $ on chemicals as recommended by Leslies.
A local pool company suggest I perform a water treatment at the beggining of this season. I am pretty sure it was borate as I needed to add a significant amount of acid (I did this before finding this forum).
On reciept of my test kit I got the following readings
H2O Temp 80
No visible algae
The CYA and the CH bugged me. I slept on it and early the next morning drained 70% of the water and refilled. That night I added the required chlorine and got the following test readings:
H2O Temp 82
I have since been keeping up with the bleach not allowing the FC to get below 5.5. It is now Tuesday and I have seen a couple of small patches of green algae.
All that and I still have algae................
