There is not any specific info in here that im posting this for but overall it has a lot of good info in it. I have bookmarked it to reference when I need it but im certain that if you read through it you will come away from it learning at least one thing.

Like, did you know that Algae grows best in a pH range of 7.5 to 8.4? I didn't!

I don't think that article is very accurate. I read the first few sections and noted several misstatements.

Then read the whole thing, specify the inaccuracies and correct them.
