the water. The addition of salt may possibly be helpful if the fish have a
minor problem of the skin, which can occur when receiving new discus
in a large shipment. But in nearly all cases, salt need not be part of your
Should I add peat to the water in my discus tanks?
Many discus breeders worldwide incorporate peat into their discus
programs at all times. Here in the United States, peat is not widely used, nor is
it used to any degree by the Asian discus breeders. However, many European
discus breeders find peat to be valuable in their discus water. Because of that
I’ve found a small number of discus breeders outside of Europe (mainly those
in Asia) beginning to show a bit of interest in peat for discus tanks.
Keep in mind that not all peat is equal. From my own experience I’ve found
that peat from here in the United States is far inferior to peat from Eastern
Canada. That Canadian peat can generally be found in most local garden
centers here in the U.S.
The effective life of any peat for the aquarium is determined by the length
of time the peat is in the aquarium filter, and the amount of water passing
through and over the peat. I’ve found that with a fast flow of water through
the peat filter, the humic- and tannic-acid properties of the peat become
exhausted in about three days.
Many say the peat will both soften the water and make it more acidic, but I
have always found that my discus water became more acidic, but not any softer.
With a tank pH of approximately 6. 5, I could lower it to a 5. 5 reading in two
days by using approximately 1½ pounds of peat in a 20-gallon tank. D
