I find that my pH usually runs around 7.8 - sometimes down to 7.5 - is this too high? What problems might it cause? When I add my daily 3-4 quarts of 6% bleach, it seems to run up the pH one level on the test kit "scale". If I shock, it runs it up 2 levels. Always seems to settle down after a...

Another reason for leaving the pump off would be the risk of something breaking and the pump running with no water. We recently had a fitting (2" PVC to 1.5" screw into the filter) crack - when the pump ran, there was spray from the crack, and within a few hours, the pool ran down to the point...

Hi everyone!! I almost can't believe it. One month later, we still have clear, sparkling water! After all the trouble I had just 1 year ago, this is soooo amazing. Thank you all so much for your help! :-D Now, I want to get things optimized for the season, I'm wondering how much Cl I should...

This seems to be a pretty cheap source for Calcium Chloride.. This is what I want, right? http://www.gemplers.com/product/CACL2/5 ... ide-Flakes $32, including shipping, for a 50lb bag of 77% flakes. I thought that was pretty good. Local pool store wants $75 for 50 lbs. Ridiculous.

I have a similar rattle. Only way I have been able to get it to stop is to put some back-pressure on the filter by closing up one of the valves to a return (i.e. increasing pressure). I haven't opened it up yet, but it sounds like air in the MPV. Wondering if it is a bad seal in the MPV? Did...

Woo hoo!! FC had been bouncing around on me, but I've been shocking the last 4 days. Finally, this morning, no FC lost overnight and CC <0.5!! I feel so -accomplished- thanks, guys! Water is looking blue and sparkly.. So happy! Now, what is next? Here are my readings - I added the Baking Soda...

Replaced water to lower CYA - Validation of next steps.. Thanks everyone for the advice so far!! We pumped out 60-70% of the water and replaced. The green is gone, and we have sparkling blue water and white walls (not greenish) in our pool for the first time!! (Last year was a high CYA...

Ok.. I went a little aggressive with the draining. Figured it would be better to get 60% of the water out while I was at it. I figure better to get the CYA down to 20-30 and work up, rather than being frustrated with high chlorine needs. It's going to take a while to fill back up at 10 gpm, vs...

Also, some pics of the progress so far! (Haven't started pumpung out yet..) Greenness.. [attachment=2:144kwh11]IMG00036-20100429-1057.jpg[/attachment:144kwh11] Shallow End [attachment=1:144kwh11]IMG00037-20100429-1058.jpg[/attachment:144kwh11] Pump / Filter setup...

Thanks, everyone.. I was looking at the shock chart and wondering whether it would be better to drain 1/2 and refill to lower CYA rather than buying all that bleach. Sounds like that is the concensus. Do I need to worry about anything when removing that much water for a plaster pool? Don't...

Hi, everyone! This will be my first season on BBB - started late last season and liked what I was seeing. I'm looking forward to being a full BBB guy this season, but need some guidance. Here are my specs: 16'x36' rectangular, 3.5' shallow, 6.5' deep = 21,600 gallons (give or take a few...
