i used one that was close to that i was a coraline part a And part B mix. it didnt really do much. my skimmer took most of it out. but you can try it. i would stop if i see the watter getting cloudie
I don't believe in those products, I think there a waste of money. I'd rather spend the time and money on kalkwasser to keep my cal-alk-ph levels stable. Once I started dripping kalk my coraline went nuts know I have to scrape it off the front glass almost every week.
Yeah I use kalk in my two other tanks but on this one there is no sump/fuge so I can't drip and kalk is not supposed to be added to the main tank. I have pretty good coraline growth but I want it to look like my other two tanks. Thanks for your info.
