It’s not only people who feel discomfort, fish can too.
Stress in fish is caused by incompatible species being put together in one tank, overpopulation, an unsuitable diet, the wrong temperature, quarantines that are not upheld when animals are added to the tank, or water pollution (elevated nitrate levels) due to insufficient or disturbed filtering (flow rate too strong/weak). Stress factors can be discerned by such symptoms as apathy, hiding, loss of colour, refusal to take in food or accelerated breathing despite sufficient oxygen content.

Improving respiration
The oxygen released by JBL Ektol cristal relieves respiration and reduces the penetration of harmful ions, such as nitrite, through the gills into the organism. JBL Ektol cristal supports medical treatment for parasites such as single-celled animals (ciliates, bacteria) in the mucous membrane of fish.

Accelerated recovery
JBL Ektol cristal stimulates the fish to accelerate regeneration of the mucous membrane. JBL Ektol cristal promotes the stability of the fish by adjusting the salt content, and is particularly effective for live-bearing fish which stem from brackish water areas or are accustomed to harder water in captivity.
