Aquarium fish treatments and medicines

Q: Can an aquaponic system be treated?

Not in the loop: the directions for use of eSHa 2000, for example, cover ornamental fish and exclude animals intended for consumption. Move the sick fish to a hospital tank and treat it there; you protect the biofilter and the crops, and you treat a much smaller volume.

Q: Should activated carbon be removed during treatment?

Yes, before the first drop, and switch off the UV steriliser too: carbon, resins and UV capture the product. Fresh carbon put back after the course removes what is left of the treatment.

Q: Should the temperature be raised to fight white spot?

Not with eSHa EXIT, which works in tropical and cold water alike. Heat only speeds up the parasite's development; in cold water, the spots stay visible for longer without the course having failed.

Q: The white spots are still there on day three: has the treatment failed?

Not necessarily. The visible spot is a parasite lodged under the mucus, which stays in place until it detaches. What matters is that no new spots appear; if the fish are improving, the course is extended for 2 or 3 days at 10 drops per 100 L.

Q: Does aquarium salt change the pH?

No, it changes neither hardness nor pH. It is dosed according to the volume of fresh water added, never the total volume, because it does not evaporate and the filter does not remove it; some plants are sensitive to it.

Each treatment targets a specific cause. eSHa EXIT treats white spot and velvet, with no copper or formaldehyde; other formulas target skin and gill flukes, nematodes or hole-in-the-head disease. Broad-spectrum eSHa 2000 treats more than 18 bacterial and fungal conditions in a course of 3 consecutive days. If a course has no effect, its product page advises checking the water: a full water test often finds the cause that no bottle can treat.

Three rules recur on the product pages: remove activated carbon and switch off the UV before the first drop, as they capture the product; dose according to the actual volume, for example 20 drops then 10 and 10 per 100 L with EXIT; and keep the filter running. In aquaponics, as the eSHa 2000 product page points out, these products for ornamental fish must not be added to the loop of a system whose fish or vegetables you eat: a sick fish is treated in a hospital tank. Aquarium salt supports recovery, at one heaped tablespoon per 20 L of fresh water added.
