Wow, nice water for Rift Lake cichlids, not so good for tetras
You could get a reverse osmosis unit or make distilled water and mix it 50/50 with the tap water. That would give you water that is more suitable for the rainbows, a low enough GH
for the tetras and other fishes, and remove the sodium from the water softener.
If money isn't an issue, you can buy reverse osmosis water from some pet shops.
Reverse osmosis (R/O) units waste a lot of water and might not be suitable if water is limited. You can get them from most hardware stores or online. If you do get one, look for a unit that has a 1:1 ratio for the waste water. R/O units produce waste water that has all the minerals and nutrients in. This is normally discarded down the drain or on the garden. Cheaper units often have a higher waster water ratio (2:1 or 3:1) whereby they waste 3 litres of waster water for every 1 litre of pure water they produce.
The other option is a solar still. You can make a solar still, which would give you pure water, no waste water and be free to make pure water, it just requires a bit of sunlight.
Get a large plastic storage container and put it outside in the sun.
Pour a bucket of water into the storage container.
Put a clean bucket in the middle of the storage container. Have a rock in the bucket to stop it floating around.
Put the lid on the storage container.
Put a rock or small weight on the lid in the middle, so the lid sags above the bucket.
As the sun heats up the container, water will evaporate and condense on the underside of the lid. The water will run towards the centre and drip into the bucket. When the bucket is full of water, you put it into a holding container and put the bucket back in the storage container with another bucket of tap water.
You get pure water with a pH of 7.0, 0 GH
, 0KH and no wasted water, no power used and it's cheap to set up. You could then use this water mixed with the tap water to get a better pH, GH
for your fish.
