I am getting very mixed messages and need a simple answer.
I have a 20 gallon and 29 gallon tanks both of which i want to be planted.
Both tanks are currently planted with anubias, crypts, carpet swords (i thing), java fern, wysteria, vals and cabomba. On my 20 gallon tank i have a 20W 10000K T12 light, which has a reflector. Everything is growing perfectly, the cabomba is branching off and the anubias is growing like crazy, the other plants are slightly new.
IN my 29 gallon tank, which is a mirabello 100L, came with a built on hood, it has a 12W bulb which came with it, and an 18W bulb (its a double hood, which holds two 18W bulbs). The 18W bulb is 10000K, T8 and with no refelctor. In this tank i am haing problems, i.e plants not looking as good as the other tank.
At my lfs they continuiously tell me its not lack of light, that 10000K is sufficient. From all i have read that is not true, i need wattage rather than K. My mother aggrees with the fish store, and i need proof that this is incorrect.
So what should i do? I am sure i need to upgrade the lighting, but i am not sure how and where to get cheap but sufficient stuff in australia. Also how would i upgrade an build in hood (attached to the tank)?
So to conclude, Is K important or wattage? How to upgrade? thanks guys
