GREAT PRODUCT
I have a 3 tier fountain and have tried many algae preventers which were more expensive and none of them come close to this product. I put 1 tablet or block, what ever you want to call it almost 2 weeks ago and the water looks like I just filled it, can't say enough about it, very pleased , plus it's cheap.

OLD LABEL- The mfg. has relabeled the product.
The product application instructions as shown on amazon are old and incorrect.The actual product label application instructions call for one block per 30-80 gals of pond water.This is old advertising!!!!!

Algae Under Control
I've been looking for a quality algae control for awhile. The liquid ones have gone up in price but don't really control the algae that grows in my fountain. This one does the trick and is reasonably priced. We placed this in the fountain and it goes to work. No need to remember to add it quickly. We were gone on vacation and thought for sure we would need to clean the fountain upon our return, but no, the algae block did its job. Would definitely recommend if you have an algae problem.

Only lasts a few weeks...
I threw one block of the Fountain block in my new fountain and it kept the algae away for about 2 1/2 - 3 weeks. Then the algae started growing rampantly so I threw another block in the fountain to no avail. The algae growth got so bad that I had to completely drain the fountain, scrub off the algae, and then refill it with clean water. And the remaining Fountain block was still about half the original size.I bought 3 packs of the stuff, so after cleaning my fountain, I put a block in each fountain level under the theory of overkill to see if it would keep the algae away for a longer period of time. I'm keeping my fingers crossed.This is my first fountain, but the store that sold me the fountain told me this Fountain block stuff would keep algae away completely. Well, I guess experiences will vary.
