Hi

I have:

Dimensions: 201cm W x 51cm x D 70,5 cm H
Volume in litres: 717
Volume in imperial gallons: 157

External Filter
1550 l/h External Filter Rena Filstar xP4

CO2
JBL Proflora CO2 Set Profi 1
http/www.zooplus.co.uk/shop/fish/technic...ories/co2/19466


4 x 58W (232w) - 150cm lighting system

Another member recommend aiming to get 3WPG by fitting an

Arcadia luminare. T8 modles can have aditional tubes fitted to boost lighting.

Searching online and im really stuck on how this works

Pointers appreciated

Regards

John B

The "Watts per gallon" rule is in the same category as the "inches per gallon" stocking guideline. It is a guideline. The Wattage needed does not increase linearly with volume, rather as the volume increases, the rate at which the wattage needed increases falls off. Large tanks do not need the vast lighting that the Watts per gallon guide would suggest.

Are your plants growing well with the current rig?
