This is interesting.... low-light pearling?

Here's the backstory... I was buying all the Nymphaea zenkeri I could find at one of the local petco's because I've got some CF lights coming in a few days, and I wanted some that were already sprouted.

So, in the tank they also had what looks like cabomba, which required high light, but they had it floating in a twisted mass, and I asked the employee bagging my plants how much of the cabomba I would get for the $2.29 price tag, and he said:

"well, usually we only give you a few strands but this stuff is all floating around together, tell you what, I'll give you half of what's floating"

:dance: I got about 2 or 3 bunches worth of cabomba for one!

Anywyas, since my CF lights aren't here yet, I decided to let the stuff float under the 40w NO tube on my tank, and keep my fingers crossed that it makes it till the lights show up.

So the zenkeri is doing great... couples leaves already after about 1 week.

Today I did a water change, and left my filters off so I could rinse out the sponges, and just decided to plant the cabomba on a whim.

Low and behold the darn things are pearling, along with a couple of the zenkeri, and the apongogeton natans! They've been going for well over an hour now....

I can understand why the cabomba would pearl for a while, but the other stuff?

The plants are 24" below the surface, only a 40w NO light above them. No CO2 right now (I have the hagen DIY system, just haven't got it started yet)....

Anyone else experience this before? I'm expecting it to stop in time, but wow.
 
Interesting... but I thought they needed a lot of CO2 to produce the O2? I guess I've got a lot more to learn lol

Here are some tank shots... a humble begining mind you:

Still some plastic in there:

When you do a water change you can saturate the water with O2. The plants are technically pearling, but this is because the water has SO much O2 in it, it won't dissolve and bubbles to the surface. Mine really looks cool after a water change, but then only does it a little after a few hours. I've got 130 watt PC's with pressurized CO2.
 
Ah I see... I thought it was just trapped bubbles at first too, but it was a very steady stream . . . . . . . . . . . . . . . . . . (like that)

But I guess I'll have to wait for the CF's to see true pearling.

Oh, the statue heh, just didn't put it back upright after the water change... the zebra rock stands up too next to Sidhartha
 
Mgamer, you know your stuff with plants, I want to ask about actinics.

I know they're worthless in planted tanks, but they do bring out the colors of a lot of fish, so what I want to do is keep my CF's at 10k, and keep an actinic, or 50/50 on the 40wNO tube I currently have...

My question is, eventhough it wont help the plants, will it harm them? Do I need to worry about algae with this idea?

TIA,
 
Great! I was hoping they wouldn't damage anything... I'll probably try a 50/50 first, then actinic if that's not enough blue, but I mainly want it to intensify the color of my blue dempsey, and the irridescence of the congos and boesemani rainbows.

Thanks for the help guys
