Watts Per Gallon
Hi all,
Just like to enquire, when the amount of light is rated watts per gallon, what is the standard depth? Is 3 WPG for a 2ft deep tank the same for a 1ft deep tank? Surely the effect must be different. Can I have some opinions please? I have a 2 ft X 2ft x 1ft (L X D X H) which I am planning to use for for a planted CRS tank. Planning to use 110W (2X55W) - too much? or is 72W (2X36W) enough? Thanks. |

Yes you're right, the effect is different. The bottom will receive less light if it's 2ft deep compared to a 1ft deep one.
It's too much for most people, unless you know planted tanks very well. 72W is enough already |

3wpg is a guideline when using FL tubes. can be applied to PL too but when you use T5 or mh lights, not really relevant.

watts per gallon
3 to 4 watts is a good start but you also need to keep in mind what type of plants you want to do. For example if you want to do "red" plants you might want to consider a actinic or "blue" light with a full spectrum daylight. Regardless your 1' height gives you many options without to much concern with wattage. EXAMPLE: I had a 4'x18"x12"tall with a 40watt. single tube and had almost no problem growing anything. GOOD LUCK!

On the other hand maybe 72w is enough because I am not planning to use CO2. BTW any suggestions for the plants to suit the conditions? Thanks in advance. |
