lamp is 1 year old. it is special plant growth tube with lots of light in red/blue spectrum. i can however look into increasing wattage in the future, im just afraid of algae wich aleady is a problem (i have green dust algae i belive).
i have lots of red cherry shrimps and few amanos. and i want one bamboo in the future.
water change is once a week but i havent noticed plant response to wether i change water or not. but if i stop dosing traces plants get yellow, if i stop dosing NPK plants stop to grow and new leaves are tiny.
