I have plenty of Brown Algae, but the snails and scarlet hermits have been doing a great job on that. However, I am starting to see patches of film that is deep purple in color appearing on the sandy bottom. When I attempted to siphon it out with my water change it came up almost like a blanket.
The Hermits or the Snails avoid these areas. I attempted some research on cyano
bacteria (that is what I suspect it is) but was fairly unsuccessful, was wondering if someone new what it was and what to do about it? Would adding Live Sand to the Tank help? If so should I siphon out the sand that I have in there now?
Everything tests great 0 ammonia - 0 nitrites - 5 ppm
nitrates - pH 8.3. I have not tested for phosphates mainly because I have not seen a test kit for this.
I am currently using 6 - 15 watt aqua rays florescent bulbs - that was on my original fresh water tank as well as treated aged tap water. Switching to RO
Since I am asking a million questions anyways - does anyone know a good site for aquarium lighting - plans for building a hood?
Thanks in advance
