[APD] extra plants - ALGAE ALGAE ALGAE
Thanks for your input. I think it's helpful when people try to
"scientifically" experiment and report findings, but sometimes (most often)
we can't achieve the same results. All variables can't be controlled. We all
have different water supply, different fish (the wisest of us will choose
some algae-eating fish for a planted aquarium, with the focus on plants, not
the fish) ... substrate ... I played a bit with different sizes, substrates,
location (within my house giving different amounts of natural lighting)
different aquarium lighting, different fish ... and found grossly different
results. Each tank required different levels of maintenance or gave
different results. I learned which plants worked best within each tank. And
some were unworkable (for example, 10 gal kitty litter substrate tank on a
box window, packed with plants and few fish (fertilization was controlled
externally) never worked as opposed to a 10 gal flourite substrate right
next to it, which btw, was packed with masses of breeding fish). Made no
sense to me. But it is helpful to hear about these. We can put together and
estimate, perhaps not come to a die-hard conclusion. We can theorize and go
from there. Maybe eventually find what works.
And then there's the intangible. I think Tom just has a green thumb,
selectively, toward plants, though ... not algae ;-)
I think the fault lies with this hemichromis. I do.
