Worth Reading: I have been a pool owner for 16 years and a…read morecustomer of Leslies Pool Supply in Commack. I had a problem this year (for the first time ever) with my pool holding chlorine, where after 2 hours of shocking (Using Leslies Power Powder Plus, which they say is the best you can get), the water registered ZERO free and ZERO available chlorine. Leslies tested my water and all other readings (CYA, TA, CH, ETC) were fine. They tested for Nitrates (Something I had no idea about) and told me it was 30 ppm and I had to drain 3-4' of water from my pool to dilute the Nitrates. I mistakenly listened and did this, causing me to have to re add stabilizer and calcium hardness up (over $200 worth), at my expense, not to mention the expense of adding water. Shocked my pool again. ZERO Chlorine after 2 hours! They now suggested that I drain the entire pool and refill it. I THEN WENT TO CHEMEX in Smithtown for another opinion. The owner, Charlie, suggested I try his liquid chlorine before doing another thing. He said my pool calls for 2 1/2 gallons but "just use 2 gallons" at a cost of $10... Low and behold, My chlorine held for 15 hours already. The problem was that, in my opinion, Leslies chlorine that I was sold, is sub par. The water was fine. I do not blame the young kid who tested the water. I blame Leslies "training" and questionable "methods of operation". I highly recommend Chemex in Smthtown. The owner is an honest, straight shooter, his staff is competent and properly trained, and his ELECTRONIC water testing equipment appears to be far superior than what I have been subject to elsewhere. If you want honesty and a fair experience, look no further that CHEMEX , 400 W. Main St, Smithtown.

At the end of last season my dolphin robotic pool had one of the gripper tires fall off and…read moreneeded to be replaced. so I took the unit to replace the one tire and do an overall evaluation of it. after four days they gave it back to me paid $65 everything was good. Got home put it in the pool that same afternoon the rubber bands came off. went back to chemex for a second time. The guy said that something internally was cracked In the main frame another $350. picked it up everything was fine. Put it in the pool and the entire cover from the main frame that he replaced came off inside the pool. picked up the cover and bring it back for a third time. they didn't charge me. brought it to my house again after an hour of using it the same rubber tracking bands came off and now I'm back there for the fourth time. It's my understanding that Billy the technician doesn't work directly for the organization and is overwhelmed with many service calls. Seems to have a lot on his plate. To many customers waiting in line for repairs and only one tech to handle all of them. I'm going on my third or fourth week without having my pool, but regardless of that I'm getting the impression that this company is not the right company for maintenance on these robotic cleaners. Thanks, Chris.

The stuff they sell is definitely not cheap but they have good brands and quality products. Unlike the cheaper stuff at the big box stores you get to customize almost everything as much of it is custom-made to your specifications. As others have noted the salespeople are helpful (unlike the big box stores) and not pushy at all. This is one of those places I put in the category of "you get what you pay for". Definitely worth checking out.
