Hello! My name is nathalia and im from uruguay. Here it is very hard to find commercial substrates for planted tanks thats why I brought a 9L ADA Amazonia Aquasoil bag from brasil in my bag . The thing is that im setting a tank with this base dimentions: 40cmx80cm (16inx32in). For that size i would need 20 Liters of soil or more. And i only have 9. I was thinking in using the ADA aquasoil as a top layer and under it doing a homemade substrate for planted tanks. This mix would be something like red clay + worms hummus + vermiculite + perlite + inert gravel/sand. Would this be ok? I read somewhere that i shouldnt mix basic and acidic substrates (vermiculite and aquasoil perhaps) but i dont know. Please help me. Thank youu! And sorry for my english .
