Hi Folks!
After finally getting control of my algae problem after one year (my LFS was selling RO water with 0.34 phosphates!), I decided to start over. Scrubbed my old rock, put new sand in my 40 breeder, added some new rock, and now have water with 0.00 phosphates.
Am thinking of adding clean up critters before I reintroduce my corals (a friend was babysitting the corals), but I noticed that a "brown substance" seems to be forming on my brand new sand bed!! Could this be algae? But from where? I placed brand new sand in the tank and, again, the water tests 0.00 phosphates (gotta love Phosphate-E).
When I stir up the sand the brown stuff does not appear to be algae, but within two days of my moving the sand around the brown stuff returns.
Any ideas?
Thanks,
C.
