Noticed some white stiff n the corner of my tank at the base of a piece of driftwood I put in the tank about 4-8 weeks ago. I've had fungus looking goop, bacterial blooms and the like before, but this looks different than anything I've encountered. It sort of looks like white spray paint (sorry for the bad pic). Not sure how concerned I should be or what to do if anything. For now seems to be on the driftwood and some java moss.
I soaked the driftwood for about 6 months and change the water about every 6-8 weeks, and ran it thru the dishwater (after doing a "dry run" to clear any soap). All has been well up until this point. pH is around 6.6 - 6.8 (still getting used to the liquid testing kit). Ammonia, nitrates & nitrites are zero. Tank routinely has reading like this, but still a little new to having more acidic water. Water was always reading in the mid to high 8s until 9ish months ago went the water company was messing around in the neighborhood.
This is a bare bottom tank with newts. Temp is 63 - 66F. I have a few Pyrex bowls with 2 swords, some vals, some lava rock with java moss, free floating stems plants like anacharis, cabomba, etc. and some floaters salvinia, water lettuce and frogbit. All plants doing fine, not rotting. Newest addition other than the driftwood was the moss an lava rocks about 2-3 months ago (both thoroughly rinsed before being placed).
Any advice or comment are welcome and appreciated. Thank you
