..for my aquarium ofcourse
Currently, I have sand in my aquarium, but I would like to have grass. What type of fast-growing grass can you guys recommend me? Im not gonna use CO2
I let my LED
lights on for about 9 hours a day.
Whats the cheapest and best substrate?
Also, Im kinda a lowtech user: i have never checked the water values or used any nutritions.
Do I have to use nutritions, or will the poop from my fishes be enough? If i start using nutritions, will i have to start checking the values?
I have 160Liters. 3 gouramis and 15 guppies
