Ahh well i havent really worked with a smaller tank then a 10g, but with 3 wpg which is a good amount of light id suggest 1/4 tsp of yeast and 1.5 cups sugar. It might be the same as a 10g which could be 1 tsp or 1/2 tsp yeast and 2 cups sugar, but im unsure if the amount of C02 in a 10g setup Diy would be too much for a 5g tank. So if it was my tank id try a 1/2 tsp yeast and 2 cups sugar with fish just to see if they can handle that much C02, if they cant cut back on the yeast and this should make it produce less C02 and for a longer period. This is my opinion and maybe someone with a 5g setup can add to this but the only real risk could be suffocating your fish.
