Excellulator..I will look into that...im giving them 530ml of Canazyme and 250ml of Aquashield. I stopped bleaching them. it looks like the dead roots are falling off by themselves now..and new white and shiney roots are coming out...i'll try the excellulator tomorrow and hopefully they will get a good rinsing and new hydrocroutons in their new pots in a week which will help them get more aeration/oxygenation...thanks for the tip, i do need them to grow more new roots not only attack the darn fungus....thank you...:)
