We have a Dolphin Diagnostic - the teal and pink one We love it and its about 3 yrs old One of the pink rubbery "feet" is wearing out (sort of like bulldozer treads) Has anyone bought spare parts for their Dophin and had a good experience with a company? thanks!

I need to refill the tiny bottle of Phenol Red in my Taylor test kit. The number on the little bottle is R-0004. I thought I was ordering the same thing (from Leslies) and the 2 oz bottle says R-1003J. Its labeled pH Indicator Solution, Phenol Red. Is it the same?? TIA! Heather

I guess she was done with it..... sigh its a small 225 gallon tub, I tried shocking it overnight but it still looks like an icecream shake was poured into it... should I just empty it and start again? keep the jets running so water goes through the filter?

Our last solar blanket was shedding blue dots so we tossed it. No matter how careful we are with the white cover-cover while its on the reel, they never seem to last more than 2 yrs. Please help me decided what weight and to choose and between blue and clear. Thanks - Heather

We have a 12-year-old hot tub whose manufacturer was "bought out" years ago and we have been unable to get a copy of any owner's manual for this particular make and model. How can I determine the volume of water it holds (eg. in gallons) so I can more accurately do the pool chemistry balancing...

We have a 1997 Savannah Excaliber spa (that we recently bought from friends) in good condition but which had sat unused for at least 4 years. We've now got it cleaned out and running fine (and balanced -- thanks to your website!) but it continues to have a small, but annoying, leak. We've...

I drained and refilled because of high CYA (pre Pool School problem) Then I had no CYA, so I have been chlorinating/adding CYA with Dichlor and I was getting into Low pH (not unexpected). Our pool does have a lot of aeration last night with a pH of 7.1, I added 50 oz of Washing Soda (A+H) as...

Sorry that sounds odd but I put my 25 ml of pool water in, add 20 drops of R-0010, then 5 drops of R-0011 and the sample is Fuschia pink I start dripping in the R-0012 and after 2-3 drops its noticably turning purple Around 10 drops its a slowly become a deep blue-ish purple, so I THINK I have...

We have one set of blue tiles right at the water line of our (old) re-fiberglassed pool. The grout is almost all dissolved - most likely due to my poor chemistry before I found this site! Are there any recommendations for new grout? I have seen grout that cures underwater online, but they dont...

I drained and refilled to get rid of high CYA and solve algae problems. I understand much more now thanks to the School and Forum I need to add some CYA to protect my FC, and I have a whole bucket of Trichlor pucks. But I am scared that I will end up with low pH problems. Is it EVER ok to...

I have always used it - now I am wondering if I really need it or if I have been adding it just because. We have city water - no problem with brown water ever I am planning to drain/clean/refill our small 245 gall Hotspot this weekend. Do I need a $9 bottle of Metal Gon?

In Leslie's FAS-DPD - does anyone know? I am going to do a drain/replace to reduce my CYA but I am going to run out of reagent very soon (because you need to use 7 ml per test!) I had to do a 50:50 dilution with fresh water:pool water to get what I hope is an accurate CYA, and its between 160...

I just got my new Leslie's Chlorine FAS-DPD Service Test and so I am a beginner (even though I have lived with the pool for 10 yrs :( My TA is 300 but my pH is only 7.3 I know my CYA is high, over 100 pH is ALWAYS low - I am always adjusting up, have never ever added acid in 10 yrs. How...
