No, It is green and is very stringy. I don't however notice it on the plants
with the exception of the Giant Val. It also doesn't seem to grow very fast
which I think is due to the large water changes I make. An earlier post
asked about my phosphate/nitrate level. Both are low, due to 60% water
changes done weekly. It is also possible that my farawella, whiptail cat,
plecostomus, and/or ghost shrimp consume some of the growth.
Also, several posters have said that my substrate of potting soil could
be influencing this algae growth. I beleive that this is entirely possible,
because after a week, the tank takes a slight greenish tint to it which
I assume is free floating algae. This is one reason that I make large
water changes, and it helps immensely.
I am changing apartments in June, and have thought about going to sand.
I would also be interested in using laterite as a base, but am unsure of
where to obtain it for a reasonable price. Also, what type of sand do
you use? Is silica sand or the play sand used at hardware stores acceptable?
