Re: Aquatic Plants Digest V3 #868

Hi all I would like to introduce myself my name is David Sanchez. I am
an avid keeper of dwarf cichlids from South America, Apistogramma in
particuler, and I'm very excited about joining this forum so that I
can learn more about aquatic plants. I love aquatic plants and have
been keeping them with varing degrees of success since I started with
Apisto's many years ago. I love the natural majestic look a heavily
planted tank gives to an aquarium.
My question is this, I have had very good success with flourescent
bulbs on my tanks. I have always had that explosive growth. I usually
go 3-5 watts per gallon or about 4 tubes over most tanks. I use co2
injection my pH is 5.5, 0 DH, 0 KH. The problem I am having is that
recently I made a custom hood for my 65 gallon show tank in it is a
175 metal halide 5500k and two daylight 36" VHO's. I beleived this
would be a great combo after all, all I had experienced to this point
was the more light the better. Up to this point I had  rarely
experienced any major algae problems until now! my plants are not
thriving because the algae is taking over!!! HELP!!! I have always
started out with dense plantings so that algae would not get a foot
hold and this was the case with this tank as well. My plants seem to
be withering under the intense light. Is this like the coral in my
reef tank and you have to adjust the plants slowly to the intense
light? Any suggestions? I would appreciate your advice.Dave
