Actually Jim, you're right. Sorry, I was ticked off at the pump and went a little overboard. I bet we've all done that from time to time. However, Hayward is still on my list as someone not to deal with (if possible). They should have recalled that hunk of metal.

I did the two-speed motor thing I discussed above. It was cool. What the guys did at the pool pump place was keep the impeller housing and such, then pull the drive and motor; replacing it with a 2+ HP two speed motor. I brought the drive and motor home for the drill press experiment in a few...

I have the Hayward and in the years I've owned it they replaced the entire pump once, and the 'drive' twice. Right now it's dead again with a "drive stalled" error. Not a chance in the world I'll put another one in. I won't even go to the Pentair; I'm done with that fragile technology and the...

I got together with another pool owner, and through email over a long distance, we broke the control protocol for the Ecostar pump. I've been annoyed by Hayward's tactic of only giving a high, low setting on their P4 controller (with a software upgrade naturally), so this was something I've...

Scale will definitely force them apart (don't ask me how I know, I'll lie). However if that happens, the plates are not parallel anymore. If the pool company is the only ones that remove the device, I would have to wonder if they bounced it on the patio to loosen the scale. I have air in my...

good point about temperature difference depending on depth. I actually don't know. Getting into the pool stirs it up enough around the body it all seems the same. Unfortunately, it's getting into fall so I can't test it in a really hot situation. I actually have a foot or so of shade on the...

chem geek, you're not wrong, but may be giving the wrong impression. No, the sun doesn't evaporate the water, but the sun heats the water that causes evaporation. Similarly, the burner on my stove doesn't evaporate the water, it heats the water so it can evaporate. What actually happens here...

I thought I'd talk a bit about the results of all this. First, there hasn't been any change to Muriatic Acid (HCl), except that the concentration has dropped in the stores. We used to be able to buy >30% mixes anywhere we went, but now the big box stores carry stuff that is less than 15%...

When I was looking into the water softener idea I kept running into problems with it. If the pool already has a high level of Ca, it will load the water softener up very quickly. Since these things work on volume and not the actual load, they will stop working until the next regen. If you...

OK, the reverse osmosis guy has come and gone. It was an interesting experience. I live out in the sticks and use well water so here's what I did. The guy came out about 14:00 and set up his machine. My TDS was up around 4000 and I think my CH was 1000 or so. Difficult to tell that high...

Your math checks out. I had some trouble realizing where the 453592 came from. But, it should have been obvious to me; molecule in, molecule out. I guess I was mostly hoping for a solution that didn't require hiring someone and the incompetence risks that entails. However, I know a heck of a...

I outran all of you. You poor people that have to work during the day.. The RO guy called back. He will charge me $500 for the treatment and that includes rebalancing the water when he's done. It will take about 2000 gallons of water so I can have the local water delivery company come out...

OK, so I'm driving everyone nuts with this.....sorry. I just spent some time looking at the water softener idea. Suppose I plumb in a line to the pool system and take water after the filter and before the pool and run a 1" into a water softener so that some of the pool water is treated and...

Rickster, I'm not concerned about the high acid level, everything I have is plastic or pebble tech and the low ph would only be for the period of time before whatever I add to take it back up works. Could have a little trouble with the cartridge filter elements though and those darn things cost...

My CH level is around 900; I can't tell exactly because I cut the test back to 10ml so I only get 25ppm resolution so it could be from 875 to 925 or so. Like I said before, I can't find out how much reverse osmosis costs; the company hasn't called me back yet. Additionally, their add says...

Rickster, nice to have someone else looking into this. Using chem geek's suggestion, I finally determined that my CH is around 900. The results of my experiments with small amounts of water are that the calcium oxalate is difficult to get rid of. Just like Rickster I could only filter about...

OK, before I go further with this could one of the experts chime in?? I got my test kit (TF-100) today and it looks like my CH level is way, way, way the heck up there; I gave up on the CH test on my pool water. I don't want to just waste the reagents so I tested water taken directly from my...

champion1, listen closely to what JasonLion is saying. I've had this happen. When I first got my pool, they didn't explain much to me and I added salt based on a bad cell reading. New cell wouldn't work because I had the salt level way too high. Had the water tested at Leslie's, and even...

The various soldering guides usually don't allow for printed circuit boards that have been damaged by hot components and such. This is probably what you have going on. I have not seen the particular board you have, but I have repaired a LOT of pcb's that have been damaged in one way or another...

Got two pounds of oxalic acid. First test with a quart of pool water is interesting. I don't have my test kit yet, but when you have the stuff, you can't help playing around. So, I put 10g of Oxalic in the quart of pool water and stirred it up. It precipitates something almost immediately...

Re: SWG pools and natural stone decking corrosion...true/myt My experience has been right along the lines that chem geek described. Salt recrystalization upon pool water evaporation over time will break the stone. If it has layers, the layers will separate. If it has cracks, they will get...

Actually, my first experiment will be done in a 5 gallon bucket. Wanna understand this a little bit better before I commit the entire pool to it. :twisted:

I haven't actually priced the mobile alternative, but I live a little over 30 miles from there at the end of a mile of dirt road and am on a well. I suspect we're talking several hundred dollars to get this done. It costs me roughly $300 to get the pool filled, so the math kinda sucks...

I really, really like the idea of sodium oxalate. Yes, it would cloud my pool and make a mess, but that's what filters are for and when it lowered the calcium level through precipitation and filtering, I would be in really good shape. See, my pool started off at 1000, but through evaporation...

Thank you very much. I'm working from memory here, so I may mess this up. The water here has a very high CH, around 1000 or so (well water). So, just starting out we're way above recommendations and changing the water doesn't change anything. So, your notes on solubility make perfect...

Best indication is that the white crust I've been fighting is calcium sulfate and not calcium carbonate. They're both common and especially in my soil. When I got a hint at what it might be, I evaporated some water out of a glass which took about a minute here in the sun at 109 F and then...

Just to annoy y'all, I went to ACE hardware today and checked out their muriatic acid. It was exactly the same as the stuff at Leslie's. White Muriatic Acid 29%. So, my problem must be that what is collecting on the plates of my salt generator cell is not calcium carbonate any more. There...

I absolutely would take a picture if hadn't cleaned the cell recently, but it's just a white build up like that looks exactly like the stuff you see in all the pictures of dirty generator cells all over the web. Sort of like the build up on the walls of a pool that we deal with over time...

Melt in the Sun, just for an example, I took the generator off, wrapped one end in plastic and wrapped an elastic band around the plastic to hold it on and poured straight 29% Leslie's White Muriatic Acid in the cell about a third of the way up. No bubbles, so I went half way, no bubbles...

It could be the same as the fume free your talking about, I haven't seen that yet (thank goodness). But the contents list is only muriatic acid and "inert ingredients". The concentration claims to be 29%, but if it won't boil the stuff out of my chlorine generator, it couldn't possibly be that...
