chemistry

I've been reading through a few threads talking about water test kits and the science behind them. I honestly don't understand about half of what the "science types" say, though I think I get the general meaning. I use test strips because they are easy, and the one time I used the api master...

Hi Folks, Recently, I have been making good use of the UKAPS thread entitled Sodium And Plants. I would like to extend this beyond sodium and beyond plants. Hence this new thread. I have found it difficult obtaining information about freshwater aquarium electrolytes pertaining to all aquarium...

Hi guys, I know that water change is the single most important thing to maintain a well-balanced and healthy thriving aquarium, but, from what i know, it also takes away the important nutrients that plants needs, such as iron, etc I am currently only stocking RCS in my 150L tank heavily...

Hey there ladies and gentlemen. Im looking to get back into the game soon (and have eyed up a freaking lovely 135l tank with which to do so) and i have the misfortune of living in a hard water area. If i could afford the RO kit id be going for it without question but its not an option for me. I...
