| Re: Purple up??? I use it. Got it for free from a fish supplier. I use it as my calcium additive. I have a small tank( 29 gallons w/ 10 gallon fuge.) My calcium is always proper. I've even had coraline grow on african lace rock in 2 weeks time. I would recomend it to all small tank applications. the large tanks that I maintance, i wouldn't use because it's not cost effective, it's easier to use a calcium supplment. |
