HI Everyone and Tom especially,

I just started a 5 feet X 2 feet X 2 feet tank recently. And these are the parameters I have.

Fertilisation EI method Using 1 teaspoon of KNO3 every 1, 3 and 5th day, and 1/4 teaspoon of K2SO4 evry 2, 4, and 6th day. I do 50% water change on the 7th day.

Lighting is about 3.2 Watts per gallon. ( 6 X 80 watt)

Temperature at 25 degree celcius

Recently I sarted seeing a lot of Rhizoclonium. I read that this is due to insufficient CO2.

So my question is, is my lighting too high? I am thinking of using 3.2 W/G as the tank is 2 feet high and I want to make sure the fissidens at the bottom would get the light. I am only using one CO2 at one corner of the tank. Should I add one more CO2 tank to increase and make sure my drop checker is always yellow?

So in summary, should I

1. Increase the CO2 and keep the light as it is as I need to get light to the bottom of the tank.

2. Decrease the light and keep CO2 as it is?

Thanks a lot.
