Spending too much money on chlorine?Check out the Sunken Treasure!How Does It Work?The Sunken Treasure houses a chlorine tablet and takes it deep under water. There it cleans the water thoroughly and efficiently, at the bottom of the pool. The unit dispenses all the chlorine. None of the chlorine is wasted into the air as with floating dispensers. When the chlorine tablet is dissolved, the unit floats to the water surface for convenient refilling. Why Is It Better Than a Floating Dispenser?With traditional floating chlorine dispensers, much of the chlorine is wasted since it is sitting on the top of the water with much of the chlorine being released as harmful toxic fumes into the air. With the Sunken Treasure, however, ALL of the chlorine is utilized in the pool water since it is fully submerged, releasing chlorine and cleaning the water from the bottom up. This eliminates the need to stuff a floating dispenser with as many chlorine tabs as will fit. For the Sunken Treasure only 1 chlorine tablet is recommended, 2 tablets for a unit in the deep end of a diving pool. Will it Work for My Pool?The Sunken Treasure chlorine tab dispenser was designed and engineered to work well in pools and spas all across the country. It also works very well in extreme heat climates with low or high humidity. For best results, follow instructions provided with the unit. Not recommend for dark plaster pools or vinyl lined pools as the chlorine may cause premature bleaching.How many Sunken Treasure units are enough for my pool?For a typical play pool or spa (12,000 gallons or less) - 1 Sunken TreasureFor larger pools (over 15,000 gallons) 2 unitsFor very large pools (over 25,000 gallons) 3 units Review: Works Just As Advertised - I have used the Sunken Treasure since mid May, and it’s now at the end of September. This is my first year of use. Let me briefly describe our pool: -It takes about 12000 gallons of water. -We have a homemade plastic pool cover on when not in use. -We have an ozonator which disinfects the water along with chlorine. So one tablet is enough even with a conventional dispenser. APPEARANCE: The plastic is not particularly ”high” grade or anything, but solid. The color quickly gets bleached by the tablet. The appearance is not too impressive, but it does the job as advertised. CHLORINE TABLET LIFE: The Sunken Treasure definitely lets the tablet last longer, by 2-3 days, at least. This really helps conserve chlorine. COST EFFECTIVENESS: Yes, this is an expensive dispenser, but I may have already saved some money on chlorine. And the dispenser is still in good shape, which is another saving. If I can get three seasons out of the Sunken Treasure, I will definitely save money using this over a conventional dispenser. Review: Adding up the savings... - I wanted very much to give this product a five star review. The concept is great and the product shipped quickly. My pool has sweeping jets on the bottom so I knew that I'd have no problem getting the chlorine to circulate, but therein lies my problem. While the dispenser gets pushed around by the jets, it sometimes comes apart leaving a naked chlorine tab (or two) on the floor of my pool. This direct contact stains the plaster. While it's functioning correctly though this does a great job of keeping enough chlorine in the pool to maintain sparkling clear water. And the unit, or its halves, dutifully float up when empty. I'm working out a way to better secure the halves using a nylon screw so this doesn't happen anymore, but I can't put a five star review on a product that requires modification of any sort to work correctly. UPDATE Fall 2014: The vendor reached out to me proactively to exchange my unit for another. Apparently, mine pops open more easily than it should. I've not tested the new unit yet, and won't until the spring, but I was very impressed by the vendor and I have every confidence that if I continue to have problems I'll get them resolved. Like I mentioned before, the unit works great other than the one, hopefully now resolved, issue. UPDATE Spring 2015: The replacement unit has proven itself solid and I've now purchased a second unit to help keep me going through the summer. With two tabs in each, they're keeping my chlorine at proper levels for about a month before they float up looking for more. My water temp is about 70 degrees at this point with my filter running 7 hours a day. I expect they'll run out faster as my water temperature rises in the summer, but I can confirm that these sink floats are working well and saving me money. ## Features - DITCH THE FLOATER! While a floating pool chlorinator is cheaply made and quickly breaks, leaks, sinks and fails, the Sunken Treasure chlorine dispenser lasts for many years and uses half the chlorine to clean your pool water more effectively! - SINK YOUR CHLORINE!

Always deep underwater, ALL the chlorine is used in your water -- not evaporating into the air like with a floating chlorine dispenser. This means pool owners use about HALF the chlorine of a floating chlorine dispenser! One chlorine tab in the Sunken Treasure is equal to 3 to 4 tabs in a floater! - DISPENSER LASTS LONGER. Stop buying those chlorine tablet floaters that waste chlorine and fails in one season! This dispenser stays deep underwater cleaning your pool water – not getting scorched by the sun! No more replacing the cheap pool tablet floater every season. Pays for itself in one season because you use so much less chlorine. - ENJOY YOUR POOL AGAIN.

Klein. The Sunken Treasure unit can hold up to 3, 3-inch chlorine tabs. However only use one chlorine tab in the unit for most pools. Use 2 tabs for the first use, 1 tablet thereafter. If you have a deep or diving pool (over 15,000 gallons) it is best to use a second Sunken Treasure unit in the deep end with 2 chlorine tabs. It is important not to put too many tabs in the Sunken Treasure. The super-chlorination from multiple tabs sitting in the same spot, and/or from not running the pump, could cause bleaching to the pool surface. And, it is proven that one chlorine tab is effective in most instances. **Q: How many tablets for a 9500 non- diving pool?** A: One solid round tablet should do. I have 15,000 gallon pool and I use two to tablets. To me the advantage is it sinks to bottom of pool and floats on top when tablets dissolve. To me it's better because I am not face to face with top floating chlorine units. It give pool a better concentration of chlorine. **Q: does it hold 5" tabs also?** A: The Sunken Treasure is made for 3 inch tabs only. It can hold up to 3. It is recommended to use 1 tab at a time, or 2 tabs in a Sunken Treasure in the deep end of a deep or diving pool. **Q: Are there any concerns about having these in a community pool around children?** A: No, there should be no concerns for children. In fact, one benefit of this dispenser is that it stays at the bottom of the pool, releasing chlorine far away from the pool surface where children swim and play. A floating chlorine dispenser has multiple chlorine tablets releasing chlorine gases into swimmers faces. So, buy with confidence. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Works Just As Advertised *by C***C on September 28, 2025* I have used the Sunken Treasure since mid May, and it’s now at the end of September.

I have had floaters in the past but they always just stayed in one place and never really seemed to keep chlorine levels stable. The sunken treasure does a great job of keeping chlorine levels stable. I get my water tested every week at a pool store, and since I've had this I haven't had fluctuation of chlorine levels or had to add liquid chlorine or shock, which for middle of summer and a pool that gets full sun and used daily is a life saver. Now I do keep it full with three tablets, and tuck any leftover pieces along the side of the larger tablets, I don't have any trouble with pieces falling out of the slats. So I'm saving on chlorine and chemical cost from not having all the fluctuation in chlorine levels, now I'm sure this is due to the fact that when it floats to the top I fill it up, where as before it was dependent on if I checked to see how many tablets were still in the skimmer basket! But isn't that the whole purpose of this product, I don't have to check, if it's floating I pop more tablets in! Yes it's expensive compared to floaters, however we have an older in-ground pool and we don't have the greatest circulation throughout the pool especially up near the surface, because this sits on the bottom near the outlets it gets moved around, I think that helps to keep the chlorine levels stable, compared to a floater. I have found this works exceptionally well for our pool and it's needs! I would give it five stars, but I'm waiting to make sure that it's durable enough to last. ## Frequently Bought Together - Sunken Treasure - The Original Sinking and Floating Chlorine Dispenser for Pool, Uses Less Chlorine than a Floater, It Sinks - Cleans Water - Floats Back Up, Replaces Pool Chlorine Floater, Light Blue - PoolRX+ pool unit 7.5k-20k gallons - Clorox Pool&Spa XTRABLUE 3” Chlorinating Tablets, Individually Wrapped, Kills Bacteria & Stops Algae (5 LB) --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.ro/products/3431298-the-original-sinking-and-floating-chlorine-dispenser-for-pool-uses](https://www.desertcart.ro/products/3431298-the-original-sinking-and-floating-chlorine-dispenser-for-pool-uses) --- *Product available on Desertcart Romania* *Store origin: RO* *Last updated: 2026-09-03*
