So, my tank which is about 8 months old (BUT had new sand added 4 months ago) started having diatoms pop up on the sand bed a little over a month ago when I upped my light period from 4.5 to 9 hours.
That lasted a week or two and they spread all over... but since then they have been replaced with what looks like the same thing except the color has changed to more of a yellowish green.
It's also appears to be the same thing growing on the glass which looks like film algae most likely.
This stuff grows quick. I'll stir up the sand bed and it's pretty much taken over the sand again by the next evening.
Running only blue lights.
N03 has been between 3 and 10ppm
PO4 between .03 and .1 ppm
First pic is what I believed to be diatoms that started a month ago... second pic and others is what I have now.
Thank with any help.
