It is good to know thine enemy.
So I'll post the algae primer and suggest
no more water changes (10 to 15% only)
and no more chemicals.

ALGAE PRIMER
Algae is normal and natural and needed by the lower
end species in your pond. One of the bulding blocks
of life. Our problem is when things get out of balance,
very easy in backyard ponds, and algae goes gonzo...


Green Water is caused by single cell free floating suspended in the
water column algae. String algae is long, flowing, likes moving water
and has some body to it. Substrate algae is like a fuzzy green sweater
and grows on rocks, liners, plant baskets, and is considered a good
algae as it keeps the suspended and string algae at bay. It also hosts
lots of tiny zoo plankton, insect larvae, worms and other tasties that
are good for fish to consume
along with their veggies (the algae).


ALL algae thrives on sun, fresh water, fish waste, fertilized run off,
rotting plants and blown in dirt. In new ponds and spring ponds algae
is always the first thing to start growing.


The best defense against algae is to have
LOTS of plants to compete for the nutrients,
few fish,
not overfeeding those fish,
some shade,
blocking run off (fertizler from the lawn, dirt etc.)
and cleaning up debris (dead plants, guk on the bottom).


Do not use algaecides, they only make lots of suddenly dead algae to
feed the next algae bloom. Gently remove string algae. Don't worry
about fuzzy algae that grows on the sides of things, the fish will
eat it up if they are not overfed.


Most algae blooms will pass within a couple of weeks.
Time and patience is key.
Remember patience...
and plants.
