Check Home Depot. I know the ones near me have DE. I bought 25LBS for $25.

Oh ok, the prices I have seen on the forum were closer to $600. My mistake for not checking prices first hand. At that price it would seem to be an easy decision to replace a Salt system or upgrade from manual dosing. Sorry for the misinformation about pricing.

Sorry, I haven't checked this thread in a week or more. It has a screen inside the belly plate that catches all the trash and dirt. I have found pine needles, whole leaves and lots of heavy grit (from the kids dropping pool toys in the dirt and returning them to the pool with mud still on the...

Yes the install is much the same, but at about half the price.

Great. Thanks Chem Geek. I was hoping you would drop in and give us an answer that I could understand. So, if I understand correctly, the most important part is to make dead sure the test volume is accurate. Then if I'm testing above 15 or more the 20% margin is not enough to really worry too...

I had asked a similar question about 3 weeks ago and never got a reply. My question was / is if I'm at an elevated FC level, and only using 5cc for testing, how far off will my accuracy of my test be? I'm talking FC in the 8-20 range. In other words for the course of a SLAM if I needed to...

Ok, I'm not up on my chemistry as well as some of the others here, but didn't you say that you pulled out a fountain did you mean you put it in the pool? Do you have it running now, or did you remove it from the pool? If you are aerating with the fountain then this will drive up your PH.

Looks to me like the bubbles are coming out of the return. If that is true then you are sucking in air from somewhere before the pump or you still have air trapped in your filter that is slowly coming out. Have you bleed out the air from the top of your filter? Do you see an air pocket in the...

Alex, I would like to suggest another option that I am using on my pool. Have a look at a Pulastron Pump. It seems to be doing a great job of maintaining my FC without having to do a manual add everyday. I had the pump left over from another job and thought it might work, so I got a large 8...

I know that this is a bit off subject, but in the interest of trying to help clear the water in your pool, have you thought about looking on Craigslist for someone that is getting rid of their pool so that you might find a bigger sand filter or even a cartridge one from an aboveground pool. If...

cherylt327, Sure it will probably help but if you have a sand filter, you might want to try adding a little DE to it the help get the small stuff. I know it really made a big difference in my pool after a SLAM. You don't have any info in you sig. so it is a bit hard to tell if you have a...

Also remember the CYA is going to take as long as a week or more to fully show up in your testing. So, use poolmath to get close on the amount of stabilizer to add and just wait for a while to check it. Just pretend it is already there for your FC calculations in poolmath. Hope that is not too...

Ok, so pool math says to add 74oz to a 25000 gal. pool to take it from 8.2 down to 7.2. So, if you want add a quart of muratic to start with then run the pump for 30 mins to an hour and recheck to see how close you got before adding another quart. Then retest again in 30mins - 1 hr. and keep...

Most robots are not going to climb the walls on their own. If you can get by with just cleaning the floor and brushing the walls by hand, then you might find a lot of unit will do a good job for you. I personally have an Intex auto pool cleaner that does a great job on the floor of my 24ft round...

Yes I have one that I really am amazed by. I installed it on a 24ft round pool by building a few fittings to adapt to the thread size needed. I liked it so much I bought 2 more for parts, what do you know they worked too.:D LOL. Worth every penny just because I haven't had to vacuum since June...

Anyone else using a Pulsar pump for auto chlorine input? I would like some input on setup, and if you had any problems with it being outdoors. Also does it seem to be reliable? I have mine setup to run on the same timer as the main filter pump. So, it is running about 6hr per day. I'm trying...

Sounds like if you can make it start by giving it a spin and then applying power, if it will start up and run, then you have a problem with the centrifical switch. The part you are talking about in the back is a switch that changes the power to a different set of windings for start up, and...

I think the next step might be to take apart you multi position valve, it sounds like you might have a problem with the spider gasket, that can do all kinds of strange things, like draining water out the wash while it should be filtering, or dumping sand into the pool instead of filtering the...

Ok, the wiring looks like it is hooked up properly. If you have a voltage test meter, can you tell me what the voltage is. My first guess is that this motor is a 220 volt and you might have only 110 volts going to it. If you truly do have 220 volts at the motor, then I would check the winding...

I did see a drop in CYA about 2 weeks ago, down to a little above 30 but I put some of my leftover pucks into a floater while we were gone for a long weekend to do a two for one. Kept up the FC and brought back up the CYA at the same time. ;) I even thought about adding a few more to raise it to...

Ok, so I have been reading on the forum for several months now, and have been following the program in my own pool for the last month now. My first question is what is the down side of keeping my FC in the 5-16 range all the time, if my CYA is at 40? Does it hurt anything to keep it up near or...

Re: Frustrated after drain and refill Marci, I am wondering have you started a SLAM yet. It looks like you are still dropping FC to 0 and your CC are .5- 1 so you really need to get started SLAMMING so that you kill off all that algae that is still not yet visible. I know it looks clear but it...

Re: Frustrated after drain and refill Marci, I think you should add about 1 gal. Then retest just FC. In about 30 min -1 hr with the pump running the whole time to get it mixed well. You should keep adding bleach and retesting until you get it to hold FC at 4-5. I think you need to get your...

Might seem too simple, but have you tried a new battery? The unit is just a small motor with a magnet that spins, that pill is also a magnet that is just chasing the one on the motor. So, if the motor is not turning it will just wiggle like you are talking about, until the battery gets low...

Yes the clear makes for a nicer look, but I use the purple for 2 reasons, first it helps me to see if I primed it incase I get side tracked (like that ever happens), second is because our local inspector requires it to tell if you really did use primer. Not that I call for inspections on my...

As long as it has not changed shape from heat or descolored from UV then it is fine to use. I have some that is at least 15 yrs old that I just used this yr to hard plumb my sand filter when we installed our pool this spring. It's been running 3 months now without any problems. Just make sure to...

Re: Why di Soda Ash turn pool cloudy Well I guess the moderator didn't like me trying to add my 2 cents worth to a thread about the op having a clouding problem after adding soda ash. I had the same clouding happen and thought it was related to the soda ash or baking soda as well. As far as...

Re: Why di Soda Ash turn pool cloudy I would tend to agree with you except that it was not truly cloudy, with a bright light the haze sparkled like it had micro sized little bits in the water floating around, and without doing a shock or SLAM, it went back to a nice clear pool in about a week...

Moved from another thread to prevent hi-jacking. I wasn't sure what caused it, but it took me about 3-4 weeks to get it clear again. I thought it might have been baking soda, but it might have been PH up or CYA. What I could tell for sure was the bottom 2 rungs weren't clearly visible, even...
