2.5 gallon non-CO2

Hi all,

So after doing a ton of reading (the PAR sticky in the light thread and Barr's forum on non-CO2), I decided to give a super low tech, desktop nano a shot.

So far I've figured out the dosing regime (EI but just 1x a week), substrate (aquasoil should be sufficient), lighting (14W CFL, 3" above tank). To get the point, I'd really like to do this tank w/o a heater or a filter. I plan on using a small 2.5 gallon aquarium that I'll later de-rim and paint black.

My room's temperature is stable enough that with only plants/shrimp, my hunch is that everything should be ok. What are some of the lower limits of temperatures that plants can handle? I don't think my room ever falls below 65 degrees Fahrenheit.

Because this aquarium is going to be on my desk (and near my computer), I'd like to do this aquarium without a filter.
1. I plan on using a small power head to help with nutrient transport.
2. I plan to only stock shrimp, so I figure this small bioload would mean little detritus and, thus, very little need for a filter.
3. I figure that with regular top offs and very seldom water changes (don't wanna put the plants into CO2 shock and promote algae) I can obviate the need for a filter.

Any input or experiences would be tremendously appreciated and rewarded with future photos!! (Err.. assuming I can do this w/o a filter/heater). I've already broke the bank on a 60cm.

Most plants will be fine in temps 60-78 deg F. just fine. Sure there will be some that are more fragile, but for the most part that is an acceptable range.

If you aren't going to run a filter I would absolutely plan on once a week 50% Water changes. On a tank that small it wouldn't even take 2 mins. Especially since you will be dosing EI (albeit only once a week, but I would still recommended it).

I have a 2.5 gal bowl that stays at rm temp-- it is stuffed with plants, snails, and some rogue baby guppies [who will get hauled out with The Big Green Net when they get bigger]. It's been going a couple years without filtration or heater. There is a lamp nearby. I change the water when I think of it. Zero algae.

ie: go for it!
