Therefore they are not a better size.
J. Papadopoulos
For something that supposed to keep algae out of a fountain, this one does the exact opposite algae grows in the fountain, and algae grows on the anti-– algae block.

Was thrilled to receive them so quickly.

I have tried several products to take care of algae build-up in our fountain and nothing works as well as these blocks! One block keeps it clean for weeks and by regularly putting them in, the fountain stays algae free for months!! I highly recommend them.

I had the same experience as other reviewers. Product seemed to work perfect for a few weeks, then it never worked again. The algeacide blocks literally grow algae. Really dissapointing.

I have used other anti-algesides to great success but, these TetraPond Anti-Algae did absolutely nothing in my fountain. Algae immediately began to grow as if these blocks caused groth to accellerate.

Tetra has many great products that I am happy with but, not these blocks. They were no more effective than throwing a rock in the fountain.

The blocks kept the algae away for about two weeks in a clean fountain, but after than, even though I followed directions, the algae formed. They may have kept it at bay a week or two longer than other products, but in the end, I've found nothing to deal with algae effectively in residential fountains.

I have had sooooo much headache with our wall fountain. Somewhere along the way we picked up a bacteria that took over our fountain. You have know idea what a mess it has been.
The co. we bought the fountain from were puzzled also. One day while working on the mess I grabbed a sample bottle and scrapped it across the filter in the system which was once again plugged up with this slime. I then mailed this slime to the fountain co. and said "what it this and how do I get rid of it."
That woke them up. I got a call from my "personal" rep. at the co. (She had received a call from who ever opened the bottle)
They had it sent to the lab.
The next call I got was to shut the whole system down, pitch all of the filters, bleach it out and keep the tank empty for at least 2 weeks. (I waited almost a month) Then they said to get TETRA and put a block in the tank when I refilled it. I used the regular products as always and added the block.
Honestly, I have had NO MORE problems. Our water is sparkling clear, even our customers comment on it all of the time.
For now, I would say that it had to be the TETRA since that is the only thing I did that was different.
If it changes I will let everyone know but for now I don't hate the fountain anymore.

I use these fountain blocks in our fountain only when it gets super hot out. Our fountain is in full sun, under a clematis vine that drops spent blooms into it and gets tons of birds pooping in it. Not a good situation for keeping algae down. So, I use AlgaeFX most of the time - seems to work great - but when it gets above 90 degrees F every day, it needs some help. These fountain blocks do help somewhat. I still end up cleaning the fountain at least once a week but that's better than every day. I tried just using the fountain blocks without the AlgaeFX but they aren't strong enough on their own.
