Oh, and I get full sun for most of the day too.

I never change my water either. Usually get enough turn over with all the rain we get here, esp in the winter. I turn on my UV to keep the water clear from algae in the summer.

We have racoons and herons here. But have a little electric fence wire that I have a timer on overnight, and keeps the racoons out. Actually, don't even turn it on most of the time now (not at all in the winter), as I think the racoons know what that wire is, and stay away.

The heron has come and landed a few times, but probably doesn't like that wire around the pond rim, either, and has never tried to get into the pond.

So I have never lost any fish yet to predators,... or that I know of. And of course here in Vancouver don't have to worry about freezing.

Can you PM me where you get your H2o2 from ? And what's your dose per volume ? I'm going to try H2O2 for sure this season.

I just FB'd you.

Awesome thanks!

Ya I saw the depth bylaw that's why I asked about success wintering them.

So I will have to wait for the snow to melt in my yard but I wan thinking falls/ river to a pond. Most of my yard is a hill tho so I don't know how well a pond would work without major changes.

I mentioned h202 to the pond people at the home and garden show and they almost blew a gasket. They were not fond of me even mentioning it for use in a pond with livestock.

I've read similar reactions online about the use of H2o2 which is why I never bothered to try it in the past. However, now having seen Dez successfully use it for two seasons now I'm sold! Sure it can cause problems if you over dose but we of all people know the importance of not blinding dosing something right ? :-). I'm sure it's fine if you you use it properly, and I'm sure tonnes of people have nuked their ponds by not using it properly. Par for the course for aquatic hobbyists :-)

If you wouldn't mind, could you send that info my way as well?

Pm me your email so I can send pics easily :)

My "pond" is a 180g Tuff tote and even with a cedar and chicken wire cover, I've gone outside in the morning to find a whole family of raccoons bouncing on top of the cover trying to get at the fish. They succeeded a few times in the past but now I have all sorts of ugly netting over top.

So you're lucky you don't have coons.

My parents had a big cube tank outside under their porch cover and woke up one day to a Blue Heron sitting on the edge gobbling up all their koi. That was in SE Vancouver, under an aluminum awning.
