I am beginning to get a caramel colored substance on my rock. It looks like diatom algae, but there is none on the sand. Is this possible, or is it something else?
I recently had a bad carpet algae problem & could not get it to die off after numerous water changes. Imade the mistake of letting it "burn itself out"... only got worse & made me waste tons of salt/additives. Of couse the water parameters were perfect when I had algae.
After slowly scrubbing, cleaning & bleaching all my rock (& leaving the tank covered in total darkness for 2 months), the nasty green algae is gone & the coraline algae is finally coming back. Everything was going very well for a few months.
Now the still white part of the rock is getting a slight tan color. Parameters are: Nitrate 5, Phosphate .01 or lower.... the test kit barely changes color. Everything is remaining stable.
Lights on for 3hrs a day & near darkness the rest of the time.
Actinic 3hrs, 20K 1.5hrs.
220g tank
55g refugium
30g sump
Skimmer, UV, & filter sock changed daily
Using RO/DI water for changes.
Any suggestions or ideas? I can leave it dark again if necessary. The fish are fine.
Thanks in advance.
