We ordered Fountain Block by Tetra, for our small 25 gallon fountain and like Goldie Locks would say, "it was JUST right!" Its crisp clean flowing bubbling water is beautiful and now, no algae! No measuring or mess! Pet Mountain was great in processing and shipping the order .... fast!
I live in Arizona with summer temps easily exceeding 110 for long periods. I have a 25 gallon fountain that uses about 25 gallons per day due to evaporation and wind. Having a very high bird count, there is a lot of bathing and drinking. The water level remains constant because it is connected to my drip system. However, the algae chemical level changed drastically in as little as one day with liquid chemical algae inhibitors. I used to clean the fountain every 2-3 weeks due to ideal algae growing conditions. After the last cleaning, I placed a pond block in front of the pump intake result, crystal clear water all of the time with no more scrubbing my fountain.
