All items used for preparation of water and irrigation of the soil (buckets, colanders, spoons etc.), should be plastic. If you have an external thermostat, stick them to the glass and do not hang on the wall of the aquarium with the help of metal hooks with which they are sold. The same applies to the combined instrument heater-thermostat Even fixing of luminescent lamps to the cover must be non-metallic.
For most of us to use clean seawater is not possible, because either we live too far from the sea, or the seawater is heavily polluted. Manufacturers produce salt for sostoyatelnoy sea water with the right balance of minerals that the fish need. You just have to mix the salt with tap water in accordance with instructions to obtain the required specific gravity of the final solution. Continue reading
