This is a scam, ordered some and they don't tell you that it only works with salt water but I have dirty fresh water! Now stuck buying salt every day.
I got the same issue, but I solved it by building a desalination system at home. After the water is cleansed by the oyster, the water gets extracted leaving the salt behind which can be added to a new batch of fresh water. Saves me a few salt trips to the store.
The elctricity bill is a tad bit higher, but I plan to add wave generators to the oyster aquarium so I can extract power from there just by lowering and raising an inflated ball through the water line. Should also help disturbing any deposits in the tank
do the wave generators not need more electricity than the ball peoduces?
Im thinking of powering the wave generators with wood gas power, since Im already heating my house with wood fire I just need to starve the furnace of oxygen to make the gas appear. Mimor inconvenience with the added carbon monoxide and tar, but Im sure ill work it out
that sounds inconvient and inefficient to me. idk but couldn't you use a sterling engine to prpduce electricity from the heat like on the exhaust pipe or put like a rotoe into it or something? idk if there are ready made products like that
A sterling engine are awesome so thats a big plus!
