I started using PPS-Pro on my two CO2 injected tanks a week ago and began wondering whether I could modify it for use with my non-CO2 24 gallon tank. This tank has only 1.5 wpg and is stocked with java ferns, anubias and bolbitis. I do water changes weekly of 20% and plan to maintain that. I don't regularly fertilize this tank and there isn't much algae, what's there is mostly clado. I'd like to see the plants looking better, however. Since this aquarium has been doing ok on almost no fertilization, I don't want to use PPS-Pro full strength, it would seem. Should I dilute the PPS-Pro solutions up by some value and apply like higher light, CO2-driven tanks?
