laprjns - can you describe in a bit more detail how you added the pinch valve in place of the flowmeter? I've got a USP pinch valve (5/16-3/8) I'd like to add as well. Thanks.

Gtemkin - Laprjns - you guys are amazing!!! Completely agree with Kim. Thanks for taking the time out of your Sunday to educate me on all of this. The pics make it clear!!! Just a few more questions and I think I'll have enough to proceed with confidence. (1) I like the idea of keeping the...

Huh? That sounds different than what laprjns is saying. By your method, the tap to the right of the multivalve (SW quadrant) would be the suction side. And the other tap in the SE quadrant would be the pressure side. Which would mean that I do have the correct taps for a Liquidator already...

Wow!!! Guess I've been looking at this all wrong. Can you please help me identify the suction side from the pressure side? I have always thought that the flow was from the 3-legs into the filter basket, into the filter, then back out through the pipe just below the pipe with the tap, into the...

Pic attached...looks like I have a tap both into the suction side and the output side...seems like based on the advice provided I could just resuse the taps unless I want to preserve the puck chlorinator in which case I can use the bottom of the pump filter basket as the suction area and drill...

Hi there - have just shifted back to BBB after 3 years of using a Hayward puck Chlorinator and not noticing my CYA rise until I had a big algae problem that required me to drain and restart with BBB to get under control. Like the results using Walmart bleach and now looking for a way to not...

Pool filled. CYA down from 90 to 40. Used bleach to SLAM to 19 FC last night. Lost 3 FCs to 16 this morning. Will continue to SLAM until no more than 1 FC loss overnight. CCs are at .5. I plan to check every 3 hours or so today to keep chlorine levels at 19. Time to consider a liquid...

Thanks!! Pool is drained. Filling back up now. But its going slow......should I throw in some bleach to protect against algae as I fill it up during the day, or just wait until it is filled and then combat with SLAM?

Bama - just use the Rinse setting on the multiport to drain the pool? Or Waste?

Thanks Bama. Just read your link to SLAMing and OCLT. Sounds like even though my water "looks" clear, there may still be algae consuming FCs faster than my maintenance-oriented chlorinator can pump chlorine back into the pool. And since my CYA is high, I should plan to drain maybe half the...

Thanks Tim. But it looks like Bama was right. I checked last evening and chlorine level was back down to 3. No change to the chlorinator at all. So it must be the CYA level. Looks like I'm going to have to drain half the pool as Bama suggested to bring CYA back down to where the chlorinator...

Thanks. What is the recommended level of FC for a high CYA? And where can I get more information on options and cost for a bleach injection pump?

What about if I switch to liquid bleach for a while. The problem is the daily application of it, but if that helps restore the CYA then it may be worth it. Dumping half the pool seems so wasteful to me.

I use a TF-100 kit to do all my testing. It has a strange test that involves dripping pool water and a chemical into a tube until you can no longer see a black dot at the bottom. Replacing half my water? Are you serious? Is there no other way to bring CYA levels down?
