Thank you for sharing! It takes guts (and time too!) for a hobbyist to share such information and experience especially knowing that not all hobbyist will agree. But who cares...most important is you have shared what you think will be someday helpful to fellow hobbyist.
I only wanted to highlight what I really learned from all this solutions and everything (which i first heard from a good friend) .... take good care of your water and your water will take good care of your fish
Have a great day to all!
