better growth of what? if you are talking heavily planted scaped tanks, sure i'd even lean towards ada vs any brand of shrimp specific soil. you do realize these are VERY different products right? composed of very different things. and my statement Juan shared above doesnt show any favoritism of one over the other. it simply answers a common question about one vs the other in regards to shrimp. my reply was written back in early 2015 (i believe) and still holds true now. even more so. SL soil has become by far away the most popular shrimp soil in the usa because it just works. its used by some of the biggest breeders in the USA and world because its that good.
i'm not trying to fight with you about your opinions of the products, but saying just because i rep a brand it corroborates some alternative motive. anybody who knows me, knows i dont hold back my views just for sales.
