Right im planning a nano planted shrimp tank! The tank will be a 12x8x8 jobbie whitch comes to 13l by my calculations. I have an interpet mini filter which is 200lph which would give 15x turnover. I will use a 11w light which will give 3.6wpg Im also plannign to use scent-less cat litter, is the tesco stuff ok? can i cap this with play sand? As for co2 il be using yeast with a nano difuser, is this ok? or should i dose with easy carbo? Ferts will be provided my tpn+ or EI not sure yet. Will this setup be ok to grow HC and Dwarf Hairgrass? Any other things i have missed? Wheres a good place to buy a few small rocks from? Regards, Sam.
