summer is here...
i set a nano tnak at the balcony.( about 3 weeks old...)

no filtration, no lighting, no heating, no co2,
i call it "n no tank"

-the temperature is around 8-33 degree these days
-have direct sunlight for 2 hours ( the table lamp in the picture is only for taking photography.)
-change the 3/4water twice a week

right now it is doing quite well.
-a cherry shrimp is still survival for a week.. even at 8 degree cold water.
-there is only a few Green algae on the glass. i clean it when doing the water change.

WOW! That's a really nice setup! But a shrimp that can take those extreme temperature? you might wanna start breeding him to make some super shrimps =)

Personally, I've found that RCS are way tougher than people would give them credit for (well, the ones I keep at least anyways). I've kept some RCS in a similar setup in the past, with no filtration and no aeration where heat and light were provided by a desktop lamp, and my shrimp did fine (it was for a period of three months as well). However, I can't say that I've ever kept them at temps as low as 8 degrees...

just thought but.... "why not get a heater?"
i think the heater is useless for planted tank in vancouver...summer time: warm. winter time: have heating inside. and the lighting will help too...

and this tank is only a test...to see how plants grow in low temperautre..

3 months passed.
----thinks did on this tank-----
-added black background (reduces direct sunlight, warm up the water a bit)
-added some floating plants (water more clear)
-added a fish (fine at 10- degree)
-trimed two times, clean the glass once each two weeks
-----------------------------------------------------------------------

cherries are such a versatile (and under-rated) invert. I keep/breed them in unheated soft water tanks and 28c hard water set-ups.

terrific thread! a great example of a low tech set-up.

This is fantastic! The layout of the rocks and the proportions of the grass are excellent. I can't believe you were this successful with this setup (outside, no light, no heat etc)

I like the look of this tank. Don't know how I missed this thread. I'll have to get a look at those rocks at one of these stores in person. I really like them. And I agree with you. With no fish, no reason to heat the water. Cherry shrimp do great in cool water.

White clouds are good at taking some cold temps as well. And they'd do well to spread some ferts the old fashioned way :)

Very nice setup.
