Hi All,

I am new to aquatic plants and I am not sure which light my tank needs. I have a 65 gallon tall aquarium, which is 36"x18"x24". Tank parameters are 0ppms Ammonia and Nitrite, and under 5ppm nitrates. Temperature is a consistent 80 degrees. It has a GH of about 5.0, KH of 3.0 and pH of 6.8. It's home to a P. Senegalus, a handful of Congo Tetras, a green cory, an African Butterfly, and a pair of Dwarf Flag cichlids. Filtration is an Eheim Ecco 2236 with a modified spray-bar (install kit 2).

I ordered some plants last month and have thus far had mixed results (but none really good). I am keeping a small anubias nana, a mid-sized anubias congensis, narrow leaf micro-sword (lilaeopsis mauritania), some vallisneria gigantis, some nasaea pedicellata, and later on, some Java Fern. I realize that these plants have differing light preferences and placed them in my tank accordingly. I purchased some water lettuce which later turned out to have worms, so they were removed.

The water lettuce was doing the best in the tank regardless of the worms which eventually appeared, but I removed them. The valliseneria melted but never really bounced back. Some bolbitis put up a fight for a bit, but eventually browned and died out. The rest of the plants are just sort of in purgatory. Not dead but not growing, and certainly not flourishing.

I started dosing Flourish after the plants arrived. I also used Flourish root tabs in the Flourite substrate (about 70%, the other 30% being white sand). I am still using the Flourish products, but I am not using Co2. I initially purchased an Ecoxotic E series (E-90) 36" LED fixture. The first one overheated very quickly, so I sent it back for another. The same problem is happening with the new Ecoxotic now, and I will be returning it. I have a 30" Finnex Ray2 that I used while replacing the Ecoxotic (sat flat on the versa top and didn't overheat once), and the nasaea seemed to benefit, in addition to the dwarf hairgrass (spread a bit rather than just growing tall and stationary).

I am now in the market for a new LED fixture (to replace the Ecoxotic E90) to help the plants in my deep tank grow. I am debating the 36" Finnex Ray2 or the WavePoint daylight (10,000k). Can anyone provide any recommendations on these 2, or perhaps others? I do not want to scorch my fish and I don't want to blast the 'shy' plants with light, but want the plant growth in the tank to increase. I am also very open to any other suggestions.

Thank you in advance for any help or suggestions you can provide.
 
Many plants sold in the aquarium hobby are grown emersed (partially out of water) in nurseries. These plants take a while to adjust to growing submersed. They often shed their leaves. In addition some of the plants you mention are slow growing (anubias).
 
The only thing I had any luck with not having Co2 was Amazon Sword plants with root tabs. I have A. nana I've moved from my high tech tank to tanks with minimal light, no dosing, or Co2 and they almost immediately start shedding leaves faster than they can grow them. They don't die but they don't thrive either.

I haven't made the jump to LEDs still working with T5HOs.
 
Thanks for the responses. I ordered the first batch of plants online and they shipped from the mid-west, so I'm guessing there was a good amount of shock from transferring them to east coast. I ordered both the Ray2 7,000k and the Wavepoint 10,000k. I'm going to experiment with both and see which one seems to fit the best. Also have more digging to do on Kelvin ratings and light penetration.
