1424 Gel-Tek Tetracycline 2 oz by Aquarium Products. Medications Fish Eat. To treat ES: Mix with all feed 7 to 10 days, once or twice daily. Contains Tetracycline. Do not offer un-treated food of any kind during this time. Do not combine with anti-parasite treatments containing metronidazole. Metronidazole and tetracycline are less effective (or totally ineffective) when used in combination.
However, feeding a tetracycline feed to a tank for an extended period (30 days+) does cause some unusual algae growth of several varieties. On the normal 7 to 10 day run, I haven't seen a problem. 2 ounce bottle.
