So, I posted on this before but its been a while and I could not find the thread, anyhow.... I know there is mention of getting rid of iron in water to keep the tub clean and here is my method, easy, small expenditure, and always works! I started out by noticing my sand filter in my pool would...

Sorry this is a bit long. So as some of you might know I normally fill my hot tub from my pool, due to the high iron content of my well water. Seems my sand filter cleans out the iron very well, If I have to fill the pool with the hose I'll get a green tint to the pool so I run a 24 hr filter...

So lately my PH has been spiking and I'm trying to figure out why. Todays testing: DPD method FC 4 CC <1 TA 50 CYA 60 CH 60 PH off the charts high. I normally don't keep the CYA this high but it seemed my FC was getting ate up and this change fixed it. And I know my CH is very low, but it always...

Ok, I installed a saltron mini last October (2022) and has done perfectly... untill now. We use our 450 gal hot tub everyday and I've not added chlorine since I put in the mini. But here this last week or so the tub is not maintaining chlorine levels. I run it twice a day for 4 hours each which...

So I thought I would try this Ahh-some you all talk about and was looking for correct directions. Went to the Ahh-some site and they dont even have it. One of their videos is called "How to purge your hot tub with Ahh-some" but it is not about Ahh-some but Aqua-clarity. So is there somewhere...

So I'm back thinking about a SWG for my tub (450 gal) , trying to see if there is a new greatest one or not,. Saltron mini still near the top of the list? And does anyone have any experience with Briidea Chlorine Generator ?

Maybe RDspaguy can help here.. My daughter and SIL just bought a house with a pool with a "connected" hot tub. I'm not real familiar with the built in hot tub as I've always had a stand alone one. Anyway, the tub and pool can be run separate. Ok, finally my question... when they turn the air...

So browsing here on just miscellaneous stuff I read different things on UV, in a pool it apparently eats CC's , in a covered tub obviously it does not. My tub is doing fine chlorine, and it has a Ozone set up. Is there any advantage to popping the lid off for a couple hours during the sunny part...

So I know someone somewhere said change the water in your tub every 4-6 months or something, why?? I'm asking cause my hot tub just gave me the warning to change water. The water is crystal clear, well balanced, a breeze to take care of so is there a real good reason I should change it?

So I have a new (couple months old) 450 gallon Cal Spas hot tub and loving it. I have my water balanced and I go with the MA and liquid chlorine method used here on this forum. TA is around 40, CYA about 30, Not sure on the hardness but my well water is very soft, PH stays pretty stable Maybe...

Ok, I have this CL / MA system working good in my tub, add chlorine every day and a very little MA maybe a couple times a week maintain FC at 3-5, PH right around 7.6, TA is steady at 40, CYA at 35. My hardness level s low but doesn't seem to have a negative effect. Thanks for the lesson TFP...

I keep seeing it mentioned but I cannot find what it is... shock or something? Thanks,

So what do you guys use for measuring your liquid chemicals and dispensing into your tubs? I started out just pouring from my one gal container of Chlorine (Is that CH?) and MA into a plastic measuring cup then pouring into the tub. Seems like too much chance for an accident or spillage so I...

Ok, So I've had hot tubs for 30 ish years now, never had any real problems with chemistry or a dirty/cloudy tub just thinking on changing things up. I recently got a new 450 gal Cal Spas tub so I figured now was the time. First off I live on a well but cant fill with it directly due to too much...

So why in my hot tub is it I have a very high Free chlorine content and pretty much NO total chlorine? Ph and total alkalinity is fine, low on hardness but that's just my water. Tub is crystal clear..

So I've had my Dolphin M500 for several weeks now, All I can say is YAY!! cleanest pool on the block.. ok, so I don't live on a block.. so what?:D The M500 does an outstanding job of cleaning my pool, gets everything on the floor, first step and sometimes even the second step. Does not get my...

Trying to understand how this pro remote works with my M500 I'm trying to change the "automatic parameters" on my cleaner, turn cleaner on, turn on remote, then hit the Automatic/manual button to go to auto features.. So I set the top at the middle, set the delay at no delay, then I go to the...

Hope this is the place for this.. closest I could find. I see a lot of stuff here about pool heaters, what about keeping the pool cool? We have a white fiberglass pool installed last spring, got the white on the advice from our installer so as to keep the pool cooler in the summer. BUT...

Well after tons of research, one bad purchase, then lots of advice (and prodding ;-) ) here I went ahead and ordered the M500 Dolphin. The place I got it from did not have it in stock but its supposed to be at the store on Tuesday... cant wait to toss that guy in my pool Tuesday afternoon... I hope!

So we put our pool in last spring at the new place we bought in South Carolina. Researched different pool types and decided to go with a fiberglass unit. Had an above ground when the kids were younger and decided also to do the in ground. I just found this sight recently while researching...

Looking to buy a robot and I've narrowed it down to three units... Dolphin M500... $1599 with a $100 rebate (has pro remote) Update: found another store $1350 Dolphin M400...$1399 with a $75 rebate (has no remote) UPDATE: found another store $1149 Dolphin Triton Plus... $1049 on line, free...

Ok, I have a fiberglass pool, new install last spring. Always clean and clear, but I'm looking for a robot to scrub the walls. Made a mistake and let the guy at Leslies talk me into a Polaris 825... even though I expressed my desire for a "smart" robot (he said it was) it is not, just an aimless...

Howdy,new to this forum, got my second pool last year, new inground fiberglass. Years ago when my kids we young we had an above ground. Had hot tubs for going on 30 years now so water chemistry is not new to me. Always have had nice clean water, knock on wood! ;)
