I am maintaining a 34,000 gal s/w pool with an Aqua Logic system. The board is about 5yrs old the cell is aprox 1 year old. Last year had the no cell power problem, resoldered weak spot on board and good to go thanks to all here. Now I am getting the cell power error along with cell yellow light and no power to cell. I shut power off to system like a reboot to board and cell returns to working order. It has happened twice now and am not sure if prob is with board or cell. Salt is 3100 to around 3200 all other chems are stable. Could the relay where the repair was made have finally failed or is the board at fault. No help from Goldline LOL. Thanks , Chris

Thanks Splashin

Its possible it may be mustard algae, a real pain to get rid of. you can try a jacks magic product for mustard algae. Also did your pool get a lot of leaves in it for a period of time? If so the tannins from the leaves love to stain vinyl liners.

I messed up and posted this on the spa forum. I have an Aqua-Rite board that blew what looks like a diode or theristor on the upper right hand corner of the motherboard. I remember a fix someone posted on this site a while back. I did a search and found nothing. Can anyone help? The numbers I see on the black quarter sized part are SL32 and underneath 2R025. Thanks in Advance chris

I read on this forum a while ago about a repair made for an Aqua-Rite board. The problem seems to be a blown theristor ( not sure if thats what its called),black about size of a quarter upper right corner of mother board. Numbers on part are SL32 then underneath 2R025.Looks like the things on the inside of a surge protector. Can this be repaired and if so any links to a supplier for the part would be extremely helpful. Thanks in advance, Chris

Is there a difference in using Muriatic over Sulfuric acid in lowering ph? Thanks, chris

Can anyone explain the purpose of an impeller ring?

Thanks Pathfinder. Thats just what I was looking for. Chris

Does anybody know where I can order a relay {Zettler AZ2100 -1A-15DEF 40 AMP 250 VAC} I have searched all over the internet for a retailer. Its for my heater. Had a simple meltdown from a loose connection everthing else on board checks good would like to replace this before sending board out. Thanks Chris

Chris, Something else to consider... Salt (in a pool) is a dissolved solid. Salt may or may not be the only dissolved solid in the pool. Therefore, when you have a reading taken with a TDS meter, your getting a report of all dissolved solids in the pool. It is best to have your water tested with a salinity meter to get a (true?) reading. Here is a tester that Goldline offers. It will set you back about 1 Benjamin. I have not read this whole thread, so i don't know if you have been told this: To lock in the instant salt reading Unit must be on (auto) Push diag button 5 times. while this number is displayed, move the on/ off switch from auto to super chlor then back to auto. The manual will only show you to do it once, But my experience has been (in some cases) that you may have to do it twice or maybe 3 times to get the unit to report the same level as the instant reading. Is the lock in salt reading you are describing for an Aqua Rite? I am using the Aqua Logic. I should have said I am using the Tracer pocket tester that PS558 mentioned which i believe can test for tds and salinity. Thanks Chris

I did the instant salt reading yesterday and it was at 3000 so i'm going with that. I will use that in the future to determine if I need to add salt or not. Thanks again chris

Great. So long as the system thinks the level is within its parameters its good to go. Thanks you made my life a lot easier. Chris

Ok, but wouldn't the cell get damaged if it got too low or high regardless of what the equipment thinks. This also had the "no cell power " problem. Thanks again for all the help. Chris

The water sample is always off kilter with the Aqua logic. I test it with a tds salt meter and have had the same sample tested by 2 different pool stores both with good reps. We meaning the pool stores and I are always around 100 to 50 ppms the same while the instant check is way off. No salt has been added in 6 weeks. It always seems to be running to the low side. I show 3400 and it tells me 2700-2800 been doing this for a cpl months. Goldline no help. I don't want to add salt since the samples tell me it has enough. I just want to be sure it can operate like this without damaging the cell. thanks chris

Is there any way to calibrate the salt sensor in a Aqua Logic system? I constantly get differing levels from one day to the next. As much as 400 ppm. The cell has been cleaned and tested good. the system is about 3 yrs old.
