Hello all. Im worried about using flourish excel in my tank. I searched around for a while and finally bought a 100ml bottle (as it is very difficult to get in Ireland). Ny tank is a 47G with a BN Pleco, Minnows, guppies and 4 fry , RCS and MTS. Will Flourish Excel harm any of these guys? Also, after hearing it melts anacharis, ive removed all the Elodea densa, Canadensis and Brazilian I have in my tank. I've also heard it can harm moss and ive got some Java Moss that I hope will grow around my drift wood (ive currently bound it on with thread). So I'm basically wondering, will any of my inhabitants, plant and animal, be harmed by this? Also if you have any advice on using excel, it would be greatly appreciated. Thanks!
