I have a 55 gallon tank with 6 Angelfish a Bala Shark and several plants. I've had this tank established for almost a couple months shy of a year and the issue I'm having is the slow/absent growth of my plants. I have used fertilizers (not consistently) and a couple of months ago I added CO2.
After watching several of Dustin's Fish Tank videos on YouTube I have decided that I would like to add dirt to my tank. Currently I just have pea sized gravel in the tank. I am wanting to add dirt to the tank and cap it with my existing gravel.
My question is about the bacteria in the tank. In order to drain the tank to add the dirt I would have to temporarily move my first to a plastic tub (with an airstone). Will it be safe to add them back to the tank after several fills and drains of the aquarium (to remove free floating debris and dirt)? Will I have to completely cycle the tank again? My fish are obviously my priority and I do not want to kill them, but I also want my plants to grow and propagate.
Thanks for the help!
P.S. Here is a link to a video of my tank just showing the plants:
