    Doheny Advantage robot

    Quick update after a few weeks: This is a Dolphin with a Doheney sticker on it. Pool vac has been almost flawless so far. In fact, it's cleaning so good that it's been leaving some clean streaks on the pool bottom. So, I'm running it every day until it gets the whole pool surface nice and...

    Well - pulled the trigger on the Doheney unit today. Thanks for the advice all!

    Doheny Advantage robot

    I do have one near the deep end where the equipment is. Worst case scenario for now, extension cord with water proof box for the connection and then maybe some proper electrical work when it's cool enough to run conduit. I've got a lot of options on the W side of the pool for placing a...

    Doheny Advantage robot

    I think based on eveything I've read here, the S20 seems to fit the bill for me. Wifi is spotty at best near my pool and I really don't need all the bells and whistles. Just looking for something to vac the pool for me. Just e-ailed and called Marina to see if they have it in stock or not...

    Doheny Advantage robot

    Moved to a new house with an existing pool. Decided I need a robot since there's plenty of leaves that make it in the pool. I ran across this vac on sale and it says 'powered by dolphin', so I assume it's just a Dolphin cleaner re-branded...

    Older Hayward H400 turning on by itself

    I have a ~2006 Hayward H400 heater (with the metal case) hooked up to Hayward Pro Logic automation controller from the same year. Quite some time ago (2 years), the keypad on the heater quit working. I thought no big deal as I always set the temp via the pool controller. About 6 months ago...

    Replaced GLX-PCB-MAIN board on Aqua Logic AQL-PS-8, now wireless not working right

    Hi - any update on the resolution? I'm getting the same issue with by old style GLX-TB.... remote. It just started happening a few months back. I replaced the antenna, but the remote still does not receive communications back from the base unless it's right next to it. The buttons do work...

    CYA Disappearing

    Not in my case - the pool was already in the upper 70s (we had 3 days in the triple digits this weekend), so I kicked the heater on to bring it up to 90 so the wife would go in.

    CYA Disappearing

    I'll try the overnight test this weekend. Given the fact that the pool seems to be holding a much higher level after adding CYA, and there is virtually no combined CL, I would think that it would pass the overnight test. Time (and the test kit) will tell!

    CYA Disappearing

    Yep - I check PH and chlorine weekly and sweep the steps once every week or 2 in the winter. Pool vac does the rest. Only seems to happen over the winter when the pool temp drops down.

    CYA Disappearing

    Much less then our usual paltry amount. I think like 2 - 3 inches since September. Anyway, that would not explain why the Salt and Borate levels are not dropping as well.

    CYA Disappearing

    Hmm - I could see this - it's pretty windy where we are. However, the pool is left uncovered during the winter.

    CYA Disappearing

    So, did a full test on Friday to open the pool side for swimming - we use the spa all winter long. Water was clear, but I noticed that the CL level seemed low considering I had set the cell at 100% on a 5 hour a day run. I soon discovered why: for the 2nd year in a row, CYA was zero. Added...

    How is your travertine pool deck holding up?

    No settling or cracking yet. We have expansive soil out here, so I'm expecting some rock and rolling, but none yet. Our drainage is really good where the pool is, so I'm sure that helps. Make sure they put down plenty of ABC aggregate underneath - we're about 4" deep, and then a couple more...

    How is your travertine pool deck holding up?

    Great after 1 year. Have the pavers here in Phoenix. No problems w/ the SWG or anything. There are some pavers that have voids in them, but I think that just adds to the natural look of it. Pros: - Looks better than acrylic lace over cement - Slightly cooler in the scorching AZ sun...

    Hard water and Scale

    Great advice - I had forgotten about Saturation. It's been 5 years since I've had a pool, so I'm a little rusty. I do remember adding a good amount of acid to get the PH down to around 7 or less and aerating to bleed of some of the calcium off as CO2. It seemed to help lower the TA. Do you...

    Hard water and Scale

    Hello all. We're about to have our new pool ans spa completed. This is not my first one, and I have used the BBB method in the past for maintenance - although I didn't know it had a name - I just thought it was me being ultra cheap :-D . Anyway, our fill water is very hard and I was...
