Aquatic Plants Digest V3 #1386
<< Greetings fellow aquatic gardeners, I need your help. I am working on a
captive breeding project for the critically endangered Panamanian golden
frog. A number of zoos are working to bring some animals into captivity
for breeding before they are made extinct by the wave of pathogenic
fungus that is sweeping through Central America. What does this have to
do with aquatic plants? It appears that the tadpoles of this species
are quite fond of brown algae. I was hoping someone on this list,
having battled brown algae and won, might be able to tell us what
conditions are ideal for intentionally growing brown algae. Thanks for
your help, Kevin

When I started my 55 gallon tank I used natural river rock. They recommended
not inhaling the dust from the rock while handling, and this warning usually
pertains to dust from sand, etc. with silicates, which will cause lung cancer
if inhaled. After setting up this tank, it was extremely cloudly with dust,
even though we rinsed well, plenty of residue remained in the water. I had a
terrible problem with brown algae for several water changes (about 2 months).
During that time, I regularly had to take out the 2 plants I had in there and
clean the leaves off, as they were heavily coated, and completely wipe the
walls down. It was slowly diminishing with the water changes, but was
eliminated completely upon full planting of the tank. I know everyone says
that it's due to low light, and it may be, but it was definitely a problem
when there were no competing plants in the tank, and upon the initial setup
when their was much residual silicate (I think) in the water. I also brought
over a few rocks, etc. from an old tank that already had algae growing on
them (appeared green). For some odd reason (lighting condition unchanged) I
now have green algae growing in there, but no brown. Hope this helps.
