I do a 10% water change each week (helps control nitrate levels, add trace
minerals back, etc, etc)
Backflush the bead filter twice a month.
Clean out skimmer basket twice each month
Add 3 doses of potash each season
Water test only if something changes... BUT I have low stocking levels, and
know my system, AND it is an established system
With new ponds I recommend regular testing first season, and then as needed,
but certainly following any major bioload additions (fish)
Happy ponding,
Greg

When I went at my pond design, I purposely included concepts like a bottom
drain and a shallow VF to reduce my maintenance. I have A LOT of plants,
and
do not intend to feed my fish, in the hopes that I can strike a balance of
plants and animals. So far, my first season, things are going well.

I often read in this group of people adding potash, salt, baking soda,
fertilizer tabs, etc. They test the water every 10 minutes, change water,
do
this, do that.

I realize this is not a pass/fail, yes/no answer but how much is really
necessary? I think if my pond ever gets to the point where I must spend
time
every day maintaining it, and not just sitting by it...I may fill it in.
