Diddnt read all the post. But i personaully love this stuff. I have used it on alot of tanks in the past. First time i ever used it was on My 120 when i was growing out my jar. Been in love with it ever sence. I have 5 local fish stores near me. And i cant get the stuff in them. Makes your water darker. Not like the red tanning of drift wood. But like a dark shaddy gray. Fish love it. Softens the water. And is a actuall water conditioner to boot. Makes the water like a shadded river bank or something to that nature. And a more natural vibe. Throw in a couple of pieces of drift wood. And some natural sand. And the perfect set up ever. At least to my opinion. Buy a bottle and give it a shot any ways. Just use in one week on a water change. Instead of prime or what ever water conditioner you normally use.
