Water is clear now. But my Ph is still around 7.2, so according to poolmath I need to add around 2 pounds of soda ash to bring it to 7.4. What method should I use to add this to keep the water cloudy from turning cloudy?

Thank you! I just brushed everything and have the pump running 24 hours a day. I'll let you know how it goes.

It's been a LONG time since I've had any problems with my pool (see signature, but it's an indoor pool). Typically we've had to add acid to keep the Ph correct but this year the Ph has been running low. We didn't use the pool last winter because we where traveling for a good bit and didn't...

If you don't have a speed-stir, you need to swirl the mixture after each drop, so you know which drop caused the change.

Our rule of thumb for our 400k btu heater is 1 degree and hour for the pool and 1 degree a minute for the hot tub.

there's a chart in pool school, print it out for him. pool-school/chlorine_cya_chart_shock

You should keep a record of everything that gets added and the amount and the date/time so you have documentation to help address the problems.

Why 8' deep? Our pool is 6.5' deep in the middle (slopes down from both ends) and it's deep enough that you can't stand in the middle.

if some one wants to mail me the pictures, I'll post them in this forum. fred.hillen "at sign" gmail.com

Go get a couple of survey flagging tapes at the local hardware store. Put corner stakes for the pool and run tape between the stakes giving you an outline of the pool. Now mark the outline of your deck the same way with a different color tape. You can mark off the equipment pad as well. Now...

Make sure you check the CH of your fill water before you start draining. You don't want to discover you fill water has a high CH content after you've drained 7000 gallons.

After reading the tome on "So you want to add borates to your pool--Why and How", it seemed that it would make the water softer improving the "feel". I'm not sure if it will help with my pH control. As I have an attached spa, the pH does tend to rise, so I'm adding muriatic acid every week...

Is there any advantage / disadvantage with adding borates to an indoor pool that doesn't apply to an outdoor pool - ordor, cover issues, percipating out on the ground, etc. I finally have my CYA down to 25, the temp up to 84, and everything perfect but the CH - around 185 rather than 250. So...

If you spent $90 on a good test kit, you could probably have cleared your pool up following the recommendations here for a lot less the $120 and the test kit provides chemicals for lots of tests. I have found the test kits much more reliable then my local pool stores, which rely on strips and...

We had a similar problem about 10 years ago when a hydraulic line broke on a trackhoe and sent about 5 gallons of oil into our storm water retention pond. Needless to say, cleaning this up took a bit of time and $. They first put straw/hay in the pond to start absorbing the oil, then a few...

I'm shooting for a CYA of 25 for now, this winter, if we stop using the pool for a while, I'll drain some more water and try to get it down to 20 which seems to be the recommended level.

This post has a few charts and stuff: http://www.troublefreepool.com/looking-for-a-nice-little-form-log-to-record-my-test-results-t7504.html

Not done replacing yet, two more weeks at 700 gallons per day. My well pump runs as much as my pool pump.

Thanks, I'll bring it up to 200+. I'm trying not to add too much that I'm going to drain away anyway over the next 2 weeks, but now that we have a working heater, and it's going to be 90 degrees for the next 4 days, we'll be using the pool a lot. :-D

Last question: I plugged in the desired pH level into the pool calc and with FC 4, pH 7.5, TA 60, CH 150 and CYA 35, the CSI is -0.46 which says "Potential to become corrosive to plaster". Do I have to correct this by raising CH?

Water is perfect, my wife commented last night on how there was no chlorine smell whatsoever. I think the pH is up because we've been using the spa, the well water pH is around 7.5.

Ok, so for the past 4 weeks I've been draining water to reduce my CYA (indoor pool, and I've been listening to the pool store guys and letting them do my testing). when I started draining my levels were (from my TF-100): pH - 7.5 FC - 16.5 CC - 0.5 TA - 175 CH - 300 CYA - 60 I'm draining...

Indoor pool so no real sun on the water, just filtered sunlight.

Can you dillute the standard solution with 50% distilled water to measure 25? I'm trying to get my CYA down to 20 to 25 and my readings are bouncing rather than lowering as I slowly replace water - but I'm also raising the temperature of my pool from 64 (last week) to 80 (today). I warmed up...

Thanks for all the replies. I have a TF-100 and a speedstir, here's my numbers from a few days ago and 2100 gallons have been drained since then - I'm in the process or lowering my CYA by draining 700 gallons per day - we're on a well that does 3 gallons per minute with a whole house water...

Hopefully a decent picture, white background, sun at my back. Two pictures of same sample. I took 8 pictures, half were out of focus and the ones with the sun shaded had reflections. Any ideas for getting decent pictures as well? Cl 5? pH 7.5?

You should look at adding the plumbing for solar, so if in the future you want to put in a solar array, it won't be a big deal. A friend who moved to the San Deigo area has one that runs off it's own small pump that kicks on automaticly when the temperature reaches a certain point in the array.

These guys have some good reviews: http://www.hometheatermag.com/ Remember, the ones you see if stores are going to have the brightness cranked way up and probably be under florescent lighting, which is much harsher than home lighting. It seems that all the kinks have been worked out of the...
