Step 2: Make it!
1) Make sure your container is clean and free of soap/cleaner/cat crap residues.
2) Place the container in the desired outdoor location. Make sure it's not in full sunlight all day, or you'll end up with stinky guppy soup. It should get a little sun, though, depending on which pond plants* you choose.
3) Fill it up with dechlorinated tap water, spring water, or filtered water.
4) Float the plastic bag full of guppies in the "pond" for ten minutes, to allow them to acclimate to the water temperature. Release them into the water, gently.
5) Drop your plants in. Voila! Earth-friendly mosquito killer fully assembled! Congrats!
- Check weekly for dead guppies. You should see lots of tiny baby guppies, too. Try to choose pond plants that the guppy babies can hide from their parents in!
- Make sure your container doesn't overflow if it rains! Likewise, add more water if the water evaporates too low. You may want to syphon out a wee bit of the water from the bottom, if the fish seem to be struggling/dying/not breeding at all. Make sure to replace the water with safe, chlorine-free h2o.
- Feed the guppies a VERY LITTLE bit of fish food every few days, if you're keeping them out there and the mosquitos aren't around anymore (reward them for doing their job!)
- Pinch off any dead plant chunks. It tends to keep them nicer.
- Ask a local pond-dealer pet shop, or nursery, which plants will stay small, do well without circulation, etc. I'm not a botanist, so I have no clue which plants available in your area are recommendable.
*Note on plants: They are there to consume nitrogen from the fish waste, and to give the fish a place to hide. Don't overplant, or the fish will not receive any oxygen (surface tension, remember!) and they'll all go belly-up!
