Algae is the biggest concern. Unless i seriously raise my light bar I have at least medium lght. I've had a really bad issue with cyano and green algaes in all of my tanks, not sure why. I'd rather have the tank empty than start off on the wrong foot (again) and have to wage war with algae again. Been there done that
My HC carpet is already an inch thick and covers 75% of the tank bottom.. I'm not pulling it out now - I'd pull all my AquaSoil out with it :P I wasn't planning on doing an Iwagumi setup - I wanted to do a really lush jungle-y tank with lots of different textures and driftwood hardscape. The less AquaSoil showing the better.
I would love to fill it and just be done with it. But again I'm scared that a ton of algae will REALLY make me want to throw it out for good. But I appreciate the input!
