This is my 75 gallon lowtech planted tank setup. Incidentally this my first planted tank, I usually keep cichlids or pico reef aquariums. Frankly plants are of little interest to me, but fish behavior seems so much more natural for many species in a planted aquarium. Plant growth has been fairly irregular but seems to be finally picking up after a massive initial melting period.
My setup consists of:
One Marineland 36 inch Doublebright LED at the front
Finne RAY II Daylight 48 inch at the rear
Aquaclear 110 with 2 sponges
1 inch Super Premium Dirt From My Backyard™
Some old inert substrate I had from a goldfish tank
Unidentified Eel grass I picked up at a pond
10 Blackskirt Tetras
Some random livebearers that I used as guinea pigs (some guppies, swordfish, platies)
1 male betta and a harem of three females
No dosing or other tech to speak of. Tank receives about 1 hour of daylight every day from the window. Fish seem very happy and I have had no deaths in the first month since adding fish post cycling. When I first setup the tank it took about 6 weeks for the soil to settle in. I was pretty surprised at my initial melting of plants, and I was sure the radicans sword was not going to make it, but it seems to be finally recovering.
