I need hydrochloric acid for a school science fair project by Tuesday(yes it is approved by the teachers). Does anyone know where I can find some IN STORE I don't have any means of ordering it. It also has to be pretty cheap, cost-wise. The hydrochloric acid can also just be a main ingredient in a different product but I would prefer it alone. I would also prefer a generally low concentration around 15-20%, enough that it will affect common metals in a timely manner(THIS ISN'T NECESSARY THOUGH). And a small amount too, maybe at most a gallon.This may be a lot to ask for but I'll appreciate any and all recommendations.
Well, first of all, you definitely need water conditioner if you are using tap water. Tap water contains all sorts of metals and chemicals in it that are toxic to your betta. There are a few reasons your betta may have holes in its fins: 1) It may be because of a strong filter (if you have a bowl filter) strong current can sometime damage their fins. 2) Your plants may be too sharp do the pantyhose test, if a plant in your tank snags a pantyhose and rips it, it will also rip your beta's delicate fins. It's best to remove these. (Though, in my experience, live plants are usually soft.) 3) Excessive flaring might be a problem. If you have any bit of reflective material near your betta's tank (such as a mirror) he may be flaring so much that he is hurting himself. This is called a blowout. If you want to prevent stress, then limit him seeing a reflection for 10 minuets a day. And lastly, 4, the most likely problem a fungal infection. A hole usually means there is some kind of fungus, due mainly to poor water conditions. In a bowl larger than 2 gallons, at least the water must be changed twice a week due to built up of ammonia which can easily poison your betta and make it susceptible of disease. In addition, if your bowl temperature is not in the range of 78-82 degrees, he can get sick very fast as well. The way to cure this is to raise the temperature (assuming you have a heater since he is a tropical fish), 1 degree every day until the water is set at 80 degrees (waiting everyday before turning it up a degree is a must, if not he will die from temperature shock), do complete water changes everyday for 3 days, and add a 1/2 tablespoon of diluted aquarium salt to his water. If in three days the hole hasn't healed, treat him with antibiotic (ask your local fish store about what antibiotic is right for your betta.) Hope this helped!
I think this one's most interesting: can X-ray through peanut butter.
