I've used Hikari Gold, Omega One & NLS, and was thinking about trying an HBH & OSI product. I'm not certain if I believe the hype on NLS, it tends to be pretty messy. Omega One is very clean, and I do believe I get very good growth with these. I'm considering trying massivore, Bio-gold, HBH & OSI cichlid pellets. For anyone that has used/uses or has tried any of these products, could I get your opinion or preference...
