Run the lights as long as you want, I would say no more than 18 hours, though. 16 would be good- it gives the plants 8 hours to rest and breath out CO2/ take in O2.

Great. Ill be leaving the lights on the majority of the day now.

I am having one problem though and i dont know if its because of my T5 lights. But, the leaves on the newly planted HC seems to be turning somewhat yellow. Does anyone know the reason for this? Its been like 3 days and some of the HC that i planted the first day have maybe 10% of the leaves turn yellow.

It's a 55g that I had taking up space in the garage. I was also thinking about starting up a nano reef but I think a 240 gallon planted rainbow tank would burn a lot smaller hole in my pocket considering I live only a few hours from GlassCages.

Also, does anyone know why my HC's leaves are turning yellow like this?


Here are a couple more shots from 2 corners.

This may help your lighting questions...

http://www.plantedtank.net/forums/li...5ho-light.html

With good reflectors, you want one T5HO bulb about 17-18 inches from the substrate in order to have medium high light. The light intensity will increase rapidly as you go towards the fixture (ie, as plants/substrate get taller).

You can see from the chart just how much light T5HO can put out. I used to run a similar fixture to yours at a height that gave me well above "high light" PAR, and at first things were okay. Eventually fate will catch up to you though... my aquarium turned into hair algae heaven. After reducing the lighting to one bulb and fiddling with the height, my algae problems went away again.

I grow plants underwater.

17-18" means that i will have a huge amount of light spill in the room. Not to mention it will look funny. I think I am going to switch out the current fixture for a regular t5NO eventually. For now, the light doesn't seem to be hurting the HC too much. Unless the leaf burn is from the high light...

Isnt the yellowing a defeciency? I know in some dry start methods ferts diluted with water in a spray bottle are misted onto the plants to help aid in what is lacking.

In my experience, the yellowing is just the old immersed form leaves dying as the new, thicker and waxier leaves grow in that can handle being exposed to the air and won't wilt as easily.

I can almost guarantee that there are no deficiencies present due to the fresh AS.

Well... oopsies on my part. Its about half ADA soil and half Mr. Aqua soil. Although I think there are nutrients in the Mr. Aqua Soil.. its definitely not as high in nutrients as ADA. Since its only been about a week or so i'll give it a little more time. I do see it rooting nicely.

just give it some time i did notice some yellowing upon planting and a day or 2 after the flood. if youre not too sure on the lighting just remove one bulb and only run the single bulb. This is what i did to my tank. I only added the second bulb about a week after the flood. But that was only due to noticing that the HC was growing stringy and growing vertical. you will be fine with that fixture you have unless you want to spend more money on another fixture. I say patience is the key so just give it some time and watch how the plants react then you start adjusting things.
