I have an indoor fountain that is made of copper. I would like to inhibit bateria and algae growth in the water, but don’t want to corrode the copper (or the ABS pump or PVC fittings). Does anyone have any suggestions?

I bought a 3 tier fountain this week and the water is suppose to flow out of 6 holes in each bowl. The 1st few hours they all worked, then one or two just had a small amount coming out and its running down the side of the fountain, not flowing into the next bowl..I have my pump on max and all the bowls are filled with water.

Dad and I are making a fountain-pond. The water at center is about 2 feet to 3 feet deep. We are looking to find a pump that will blast the water about 25-30 feet (or more if possible) in the air with only about 4 to 5 feet of pvc tubing attached. We have the tubing available in anything from 1″ to 2 1/2″ so adapting to the pump hole is not an issue. All of the pumps we have found that looked like they would work say “max head 35-40 feet.” We get excited, and think it means they shoot 35 to 40 feet in the air. That is not the case. I guess it means if you had a piece of pvc pipe that was 35 to 40 feet long the water would reach up there and come out. But that is most definitely not what were looking for. That would just look ridiculous. We want a minimal amount of pipe coming out of the water and a huge blast. Anyone who knows where such a pump exists would be awesome. I appreciate it.
