    I just setup this FZONE DIY CO2 setup, and its run out of CO2 so I needed to change the material. Well, I took it out and looked at the bottom of the cylinder and for some reason there is a crystal precipitant that has formed and HOT water isn't doing much to it. Is there a way I could get it...

    I want to ask people to help me solve a mystery. Basically, I'm wondering why do CO2 yeast reactors only seem to work optimally occasionally (that is, to produce a lot of CO2 for up to 2 months at a good strong stream), but most often other times, they are very weak, have a very low stream of...

    So, what is a geek to do when he is sick and can't make it to the only fish expo in town? If you are like me, you would make an android app to help you calculate the dosage of Glutaraldehyde in your tanks. Glutaraldehyde is the active ingredient in Seachem Excel and API CO2 Booster. Below is a...
