Re-opening Pond

Hello all.
May will be one year since I've had my pond. It has been pretty mild here in the northeast (long island) I was wondering If I need to do a large water change when I open my pond for this season? Do I scrub the liner, and basically start from the beginning? Thanks

Peter

hay peter , what is your water like , i dont scrub my liner, i just net out the leaves, do you have fish, and what about a filter

A few pictures and a little more detail on your pond and fish would help.

Pictures will be forthcoming. It's about 2100gallons. I have 5 fish, 1 koi, 2 shubunkin, 1 Sarassas,, and 1 fantail. All are still alive. I have a Laguna 2100 filter with/uv sterilizer. never had an issue with green water. I have a net over the pond but it wasnt big enough, so leaves did get in. I've been using microbelift until last month. Anymore info needed?

it sounds like you got a real good start on your pond ,will wait for pics

Can anyone tell me when I should change out the bio ribbon in the waterfall tank its about 3 years old and if so what is the best type to change it to

Can you rinse and re-use it without losing the anoerobic good guys?

peter try to flush it with pond water to clean it ,,that wont kill the good stuff.

Because it is anoerobic, don't have it out of circulation for more than a few hours.
