Size of Tank: 27 U.S. gallons (30"x12.5"x18"H)
Temp: 26 C
pH: without CO2 7.3-7.4, with CO2 6.6-7.2 (problems)
Ammonia (ppm): 0
NitrIte (ppm): 0
NitrAte (ppm): 5
KH (degrees): 4
GH (degrees): 4
Ferts: Flourish and clay substrate tabs, liquid Seachem Comprehensive (2ml, 2-3X/week), liquid Leaf Zone (K & Fe)(manufacturer's recom. dose)
CO2: DIY, with problems (0-50 bubbles/min.)
Lighting: 2 wpg: 54 watts "daylight" (Cool White) fluorescent T-8 (4100K)
Substrate: gravel (has a small amount of shell bits)
Filtration: one Aqua Clear 50 power filter (capacity 200 gph)
Water changes: 20-30% once per week
Fish: 9 Glowlight Tetras, 3 Peppered cories, 3 baby Bristlenose plecos
Plants: mostly Cabomba & Amazon Sword species (small to large), plus a few Java Ferns, Hygrophila polysperma, Rotala sp., Bolbitis, Anubias barteri var. nana, Hygrophila difformis
===================================
I'd like to know what the tiny, white specks are in my tank. They seem to be mostly on the 2 pieces of wood (one local piece that has been submerged for 50 years in a reservoir, and one store-bought "Malaysian Driftwood").
The specks are the size of finely ground pepper, and seem to appear only when CO2 is being added to the water. I never saw them before starting up CO2. For example, 2 days ago, I scrubbed the specks off the wood, just before I got my CO2 going again, later that day. The next day, the specks showed up again.
Does anyone know what these white specks are, if they are a problem to my fish, and how to prevent them from forming?
Thanks a lot!
