Hi, guys! I'll reset my algae infested tank this week. So, I'll take this chance and to change the substrate. I was using only very thin quartz gravel (like a sand). Now I've treated a great amount of earth worms humus to put in my tank. It has 200 cm x 40 cm x 45 cm (height) and I have about 15 kg of this soil. Look that:
I've washed, dried and sieved the earth:
As you can see in second picture, there are still a lot of organic matter in it. This is bad? I'll cover it with the same thin gravel. What do you think about? This substrate is good? Thank you.
