I'm new to the group, and we've had our pond for 2 seasons now. Last
year, everything worked out very well after the initial break-in
period. This year, we have a very bad case of string algae (I think),
and I've drained the pond. Now that the pond is drained, what is the
best bet to get rid of the algae, so I don't have it in the spring. I
don't mind filling the pond, treating it, and draining it again, but it
will drain into a garden area, so we must be careful not to kill plants
in the process. We have 25 goldfish, 700 gallon pond (should be
enough), plenty of water movement, and a homemade bio filter. We had a
few plants to begin the season (no algae problem), but they rapidly
grew to quite a few. Any words of wisdom? Our pond is one with a rubber
liner. Any input will be greatly appreciated.

Draining isn't the answer, unless you have a lot of muck build up at the
bottom and don't have a shop vac to suck it out. Why koi ponders recommend
frequent partial water changes (10%/week) over big changes, so as not to
upset the balance.

Don't want string algae? Get rid of 15 goldfish (maybe more), they're the
main reason you have it. All that rich fishy poo. Or build a bigger
out-of-the-pond filter. ~ jan
