Is this LED hood acceptable?
 
Hello, I have a 29 gallon tank with low light plants. I was wondering if this hood that's on Craigslist would be an upgrade to what I currently have.

I know that LED lights are supposed to be good but I dont feel like that hood hits the whole tank, it seems a little too narrow.

I currently have just a standard florescent 20W 6500 K tube on the tank.

So, anyone used this particular hood for plants on a 29 gallon or have any thoughts as to which would be better?

personally (hind sight is 20 20) i would stick with the current light you have, too much light and you will have a serious headache with algae. if your plants are growing with your current light then i would stcik with what you have rater then going brighter.

Well the plants right under the strip look good but the java fern at the bottom isn't thriving, the java moss is slow growing and the plants more in the front of the tank grow towards the back of the tank. I feel like this hood would light the front a little better but I worry that plants on the front will all grow inwards similar to how my plants grow towards the back now.

java ferns and java moss is slow growing reguardless of what you have weather its sun directly over your tank with co2 injection and EI ferts its going to grow slow compared to other types of plants, its just the way they are. the plants are going to always grow towards the light. and in low tech planted setups less is more as far as your lighting goes. take a peek at my aquarium journal to see what happens with too bright of a light, i also have a thread and the algae has started with some pics of how algae took over my tank and attacked my plants.

i highly reccomend sticking with what you have unless you want to figure out a new fert dose light period and possibly have to get co2 or "liquid carbon" aka excel

I know java fern is slow growing but its also turning brown. And I thought java moss was supposed to grow like weeds after established?

I do realize that this is probably not a light issue, though.

are you using any comprehensive ferts? the plant could have a defiancy somewhhere and has stopped growing/started to die if it is missing one of like 17 diffrent componets.

I doubt that light will be a step up, it's not a plant light and the bulbs are low wattage... Probably 0.1 Watt per,if you are lucky, maybe even 0.65 Watts per bulb. Maybe 4.5 Watts in total which, for a 29 gallon is too little and not likely to be the right kelvin for plants as its not intended for them, keep in mind that you cannot compare LED watts to fluorescent watts directly. My 37 gallon which is 30" long has a 24" fixture (Marineland double bright LED) and it is decent for the bright side and can be offset to provide lower light at one end for my java ferns and crypts.

I do use a comprehensive fertilizer. There are also a bunch of fish in the tank along with snails and shrimp. They are fed well.

How can you tell what component (nutrients, light, CO2, etc.) your plants are missing?

I'll look into that one. Thank you

to touch on k rating briefly, plants can use greens blues and reds you can lookup a kelvin chart to see which ratings give which colors and how much.

as far as being able to tell if plants are showing deffiancys they will tell you what they are lacking or getting too much of by their appearance. Keep in mind it is normal for plants to drop leafs as they are constantly growing new, but a large leafs drop off means something is up usually. Are you seeing anything with your plants that is raising concern?
