I have a 37g tall community tank, with no fertz and just a standard fluorescent light. I bought 2 packs of bulbs at petsmart and just dropped them in. I now have a mini-forest with long shoots going to the surface.

I'm setting up a 10g standard tank to be my planted tank. I have a layer of eco-complete, with course gravel over it, a 28w coralife 6700k light setup and diy co2 pumping into the filter intake. I took one of the plants from the 37g and planted it in this tank and thought I would see even better growth, but I haven't. The plant look limp, and hasn't shown any growth. I also put 2 packages of bulbs from petco in, just like I did with the 37g, and haven't seen any growth yet and 4 of the bulbs have a cottony white 'mold' on them.

I have no idea what I'm doing wrong. I would have expected the plants not to grow in the 37g and to grow well in the 10g...my world is reversed. If I look at myself in a mirror through one of the tanks will my reflection have a beard?

A lot of those bulbs are sort of a crap shoot, some will do well and some never will. Just make sure you aren't completely burying the bulbs underneath the substrate, allow them to breathe a bit. I have the same fixture over my 10 gallon w/ liquid carbon and haven't had any issues due to lack of light. Especially plant bulbs from Petsmart, which are mostly easy growing plants. Any kind of plant food in the newly setup 10 gallon? Root tabs? Liquid or dry fertilizers? Fish poop? Because you'll need that too.

Yeah, the bulbs are hit and miss. I've had some grow like crazy, and some just rot and mold and turn to mush. The package usually guarantees that they will grow, or you can send them back for a replacement...did that once, waited a few weeks, didn't get any response, so I figured nothing was going to happen. Six MONTHS later, a soggy manilla envelope shows up in the mail with some sprouted, semi-wet bulbs shoved in it with no water, no plastic bag, nothing. Not even paper towels wrapped around them. Just plants in a paper envelope. I'm surprised they were still wet...So all the leaves died, but they did grow back. It wasn't worth the trouble, I think.

Haha, that is really funny!

You definitely need to be dosing for a planted tank, however those bulbs can grow fine without any dosing.

Taking plants from a non CO2 tank to a CO2 tank usually requires an adapting period where the plants need to get used to their new environment to start growing well.

... a 28w coralife 6700k light setup and diy co2 pumping into the filter intake. ...
Are you using the stock actinic/10,000K bulb in your fixture? If you are, you should get a 28w 6700K, 28w 10,000K or 32w dual daylight 6700K/10,000K bulb.

I have the 28w 6700k bulb.

Should I take out the bulbs with the white moldy stuff on them, or let the go and see if they do anything?

The transfered plant is looking a little better today. The leaves are darker green and they aren't laying on the gravel now. Some of the bulbs have sprouted a little. :)

That's good. Did you know that your Coralife fixture has a ballast with a rating of 40w. It will also run the following bulbs which are around 16" long for better coverage in a 20" aquarium:
- Current 40w dual daylight 6700K/10,000K: http://www.bigalsonline.com/BigAlsC...1744/cl0/currentusa40wattdualdaylightpcbulb18
- ADA 36w 8000K: http://www.adgshop.com/8000K_PC_bulb_p/108-060.htm

the ones in the 37g tank are doing great! That is what is so odd, the 10g has the setup for plants and I was seeing less growth there than in 37g.

I got a couple bulb packs from Walmart. I didn't expect them to grow after reading others experiences. But I had read that after sending them back the replacements that would come would be more numerous and would grow better. That is exactly what happened. Now I have quite a few of them in my tank.
Yes, they did send me more replacements than I had original bulbs. But, it took them six months to do so...I don't know if they're usually more efficient than that or not. Or if throwing already growing plants into a paper envelope with no padding or water or anything is their standard procedure.

But some of those aponogeton hybrids they sell are pretty neat, and they flower really easily. I had a few that would grow the regular underwater leaves, plus water-lily style floating leaves and purple flower spikes. They were pretty cool in an open-top tank, but I had to keep cutting them back daily because they would take over the top and starve the tank for light. They were worse than duckweed about covering the top!
