If you have fish in your garden pond you will need electricity, if you don’t have fish then maybe not, read on to find out why.
If you are building a wildlife or ornamental pond then it is possible to have a pond without electricity.
As long as you have plenty of plants with no fish then it’s certainly obtainable, but it does take time for the pond to achieve a well-balanced ecosystem. Once the ecosystem is established you can try introducing one or two goldfish and see how it goes.
If you are planning on having a lot of fish in your pond without using electricity then you are heading for disaster.
As soon as you add fish into a pond they will start producing waste (poo) which is deposited in the water of your pond producing ammonia which is toxic for fish.
That waste is removed by using a pond pump to pump the pond water complete with fish waste through a filter system and back into the water.
You need electricity to run a good pump and filter system.
The reason you need a good pump and filter system is to keep the pond clear and healthy for your fish.
The pump feeds the filter system, the filters job is to remove waste and toxins from the pond, if the harmful toxins are not removed the fish will become sick and eventually die.
A pump is also needed to move the water and produce oxygen, without the pump your pond could turn stagnant, it also needs to run continuously 24/7 365 days a year.
A large pond is going to be easier to manage than a small pond if you want fish as the fish waste is diluted in more water.
If you were to add fish to a pond without a pump and filter they would only live for a very short time. You may get away with a couple of fish in a well-balanced wildlife pond but that’s about it.
There is an option of solar power which may help, but they are limited in the amount of power they have and how long they run.
A proper pond with lots of fish would run a good pump and filter system 24/7 365 days a year, using solar paneled products would not be up to to the task as they would only be on for a limited amount of hours per day.
If you did want to go ahead with a pond without electricity but using solar products I would suggest only having a few goldfish and see how it goes.
I would use a solar powered waterfall to get movement in the pond and a solar powered air pump to get oxygen into the water.
Along with the solar powered products I would add lots of pond plants in the pond and test the water frequently, adding water treatments if necessary.
Unfortunately there are no solar products available at this moment that will run a good pump/filter system, but who knows what the future will bring.
If you can’t or don’t want to use electricity to run your pond my advice is to have an ornamental pond without any fish, add a solar powered waterfall for movement and sound, add some plants to give it a natural look and some colour, sit back and watch the wildlife enjoy what you have created.
