Rated 5 out of 5 by khuben Tetra Pond Block
I believe this product is making a difference in my fish pond. Not green and slimy like before the use. I have been using for 2 months and am hopeful it will continue to be my answer to horrific pond cleanings and green water. Fish and plants doing good with it.

Rated 5 out of 5 by Danieldonaty Cannot use.
I used one of the four blocks in my 100 gallons fountain
The water turned green in a week.
II do not run the pump too often.
I realize that the blocks are not effective unless the water circulates.
Can I send the remaining 3 blocks for a refund ??
I was not aware when ordering and should have check that you need a running pump.

Rated 5 out of 5 by DrBLOOBS EXCELLENT PRODUCT
I'VE TRIED MANY PRODUCTS TO CONTROL ALGAE AND "THE GREEN WATER" IN MY POND. TETRA POND BLOCK WORKS THE BEST, AND I CAN BUY A 50 TABLET QUANTITY AT THE BEST PRICE COMPARED TO OTHER VENDORS. DRS FOSTER & SMITH EVEN SHIPS FREE. A FEW TETRA POND BLOCK TABLETS EVERY FEW WEEKS AND THE POND WATER IS CRYSTAL CLEAR.
