Low tech 5.5 Gallon: New to nanos

I've been keeping high tech planted tanks for a couple years now but I've got a 5.5 gallon and I am looking to try the nano thing but keep it low tech. So, no co2, minimal ferts, and low lighting. The plan is to grow anubias, java ferns and crypts, thats about it. I currently have 26watts over the tank but I'm not sure how this translates in terms of high light or low light. What is 26watts considered?

26 watts = 4.72 watts per gallon, which is high light. You should definitely try to get something a little less powerful otherwise you're going to have some algae problems in the future. 2-3 watts per gallon would be ideal.

The watt per gallon rule holds true for larger tanks but I thought it doesn't work with smaller tanks?

2 to 3 watts per gallon over a 5.5 gallon tank means a 10-15 watt light. The intensity of those bulbs is very low, and I'd call that low light. I had a 15 watt light over a 5 gallon tank for 6 months and could barely get ANY stem plants to grow. I had success with mosses and wild success with vallisneria for some strange reason, but stems wouldnt grow. That leads me to believe, at least, that java fern, anubias, and crypts will at least survive under 15 watts, though I havent tried it myself. IMHO opinion, 10 watts is too low.

Bunny, I tend to agree with you regarding the oversimplification of the WPG rule. However, given that you're going low light and have chosen low light plants, you could give 15 watts a shot. Will 26 watts be the death of your tank? No way. You'll probably see much better growth. However, I do think that 26 watts is probably medium light for a 5.5 gallon.

I have a 5 gallon tank witha 10 watts. My plants are growing like weeds. I have very hard time trimming the dwarf hygro; this plant grow like a weed.

I wish I had that much success. Of course, I've never tried any hygro species. Like I said, it's only my opinion, and based only on my personal experiences. Is dwarf hygro the same as hygro compacta?

I thind Coralife makes a nice light system for a nano tank. This system has 2 9watt pc lights. Check it out:

I'm thinking of getting one for a 3 gal nano.

Thanks for all the responses. I think I will bump it down to 13 watts per gallon and leave it at that. I've got enough maintenance on my 30gallon that I want this one to be as low maintenance as possible.
