Good fish food for my fish tanks. More Related info: Its mold. Ive seen some people put a paper towel in the hose where you hook it up to the sink then turn it on and let the pressure push the paper towel through to clean it. I think some people soak them in hot water or a bleach solution too. I havent had to do it yet with mine, so not 100% sure. drop pure chlorine bleach thru the entire hose and have it go back n forth - then use cold water to rinse it out - then drop some prime thru it and do the same thing you did w the bleach and then rinse it out - then hang the hose loosely (not bound up) and let air dry. I made a tool to clean odd tubes and such, but i suppose its not much different.. Its just a wire hanger bent into 1 long straight piece with a bit of a hook shaped at one end so i can stick a bit of mr clean magic sponge on the end. It works really well. hope ypu treated that wound, I had terrible problem wih my finger which I cut while cleaning my tank, some nasty aquarium germ got inside, couldn't get rid for over 6 months and horrid painful treatment. So you would rather we empty rivers and oceans of wild caught animals? Because you are miss informed about selective breading. It's something we as humans have been doing since the beginning of time. The market for aquarium fish isn't leaving. And their is nothing better or safer for nature than a fish such as Flowerhorns that if released cannot realistically survive on it's own in nature. Since the beginning?. There were more animals at the beginning till humans started multiplying and poison everything. But who cares thats something else. Best aquarium fish food. I'm sorry since the beginning of humanity. And yes you are 100% correct. But it's your dislike for what you don't understand I question. Fish like this help nature they do not harm it. A trophy fish is just that a trophy and nothing more. Yes exactly! There is no need for it! We agree. There is no "need" for the aquarium hoby either! Fill a want with a want! A Flowerhorns sole purpose is to be there and just exist just like your aquarium it's sole purpose is to sit there and exist simply to be looked at. Best fish tank food Best aquarium fish food
