i am making a 20 gal planted tank i want to know what substrate you guys recomend or a combination just tell me what you guys think
I use ADA Amazonia type I it has grown plants the best. I use RO water and rarely do I use ADA step2 or anything at all not even iron. just aquasoil and a good amount o Co2. Im starting to use ADA Malaya. It will turn the water the most sot and acidic o all the substrates and it is made or rare plants like hard to keep downoi and erio plus crypts do really well. Malaya will not cause the initial ammonia spike like Amazonia will. The brown/red color is pretty nice looking and looks very natural.
