"The Marine plant fest sounds
like a very interesting trip to say the least, but being from the Northeast,
it
still becomes an expensive endeavor."
Heck you want to go only for collecting the plants:)??
Gee, I figured snorkeling coral reefs on some nice sunny island sounded
pretty good too:)
I suppose there are worse things to do, the plants are just icing on the
cake.
Even if you don't collect/take a single plant, it's still pretty fun.
Point well taken Tom. Maybe I can convince my wife we need a family vacation.

"Some species have been tuff to even
keep alive, never mind propagated them. I have found that CO2 additions
greatly
improves plant growth."
What levels of CO2 are you using? I've thought about it but I'd like not to
use it if I can, but it might work well, Chara, snail shells etc respond well
to high CO2 levels even with all the CaCO3 present in them.
With all the aragonite substrate, not dosing Kalk/CaCl2 and just roasting the
tank with enough CO2 to dissolve that without going overboard might be nice,
I'm leary of one's tank being the mild Kalk reactor. But I guess is should
work if you keep tabs on the pH.
I haven't narrowed down the CO2 levels I use. I know it is very very little.
Basically I use a DIY yeast reactor on one of my smaller FW planted tanks. I
change the reactor about every 7-10 days and use the old reactor on my marine
system. I had some minor pH swings using this method, so I discontinued its
use. When I stopped, I noticed slower plant growth. For fun I resumed this
method, and noticed better plant growth in both the appearance of the plants, and
speed of growth. This is very unspecified, but a general observation just the
same.
I was told by the curator at the local museum that you wouldn't get aragonite
substrate to "roast" unless the pH dropped below neutral. He runs his Ca
reactor at pH 6.6. Maybe there is a way to test to see if it will disassociate at
a pH greater than 7. Interesting thought.
Do you have any thoughts on Fe additions? Kent makes a product with chelated
Fe, as well as K, Mn, Mo and Zn. Interestingly enough, I was under the
impression that FW algae could utilize K. Possibly SW macro's and the like benefit
from K additions. I know Seachems reef plus also contains Fe.
