Chelle:I am just guessing but here is my thought on the alge issue.
The amount of water in the large bowl we have ,is so much and keeps moving due to recirculating pump
.Alge doesnt get a chance to grow.PLUS our fountain is in part shade.
We ,that is SIL. Cleans the fountain and pump every spring for set up and every fall for shut down.We also have a screen wrapped around the pump to act as a secondary filter.I buy a roll of storm door replacement screen.Its flexible and porous.
Our big problem was pine needles and worms clogging.
I took allthe stones off the base and made a "screen skirt with a slit for the base,replaced the stones and havnt had a needle problem since.Worms and slugs ,not so-much
No one gives the down-side of fountain maintenance.It is worth it to sit with a glass of wine and watch the birds bathing .
ANOTHER THING.The colum we have doesnt make much of a gurgling sound because the sides are too smooth.I can barely hear it when the neighborhood is quiet.
Sorry about some focuses.
