[QUOTE="ErinCahir, post: 658878, member: 4841"]I'm not picking a fight. You're giving bad advice.\n\nOnce you have thoroughly tested and know what you should be dosing, then you can stop testing. But you should never, ever dose blindly.[/QUOTE]\nI don't even agree with stop testing. Each week I get different coral growth and having that calculated it to complicated. I don't know if it's bad testing, but I know it is not steady.\n[QUOTE="puzzles, post: 658860, member: 10031"]no need to pick a fight , every tank is different, so put your cat eyes back in.[/QUOTE]\nThat is a dumb statement. She called you out and Erin is correct. You cannot "tell" what needs what, that is a line of crap. You can tell when you need a w/c, but if you go that way I promise you'll have slowed growth and selling your "frags" won't be profitable.
