I have just finished cycling a new tank using the fishless cycling method. Ammonia reading zero. Nitrite 0. I have still not introduced fish, and have been feeding the tank with a little (about 1ppm) ammonia (every 2nd day) to keep the biological filter working.
This morning I noticed some weird white/brown dots all over the silicone in the tank - both edge seals and air tubing. See attached 3 photos (one of the air intake tube, one of the side edge sealant, and one of the empty tank showing clear water). Whatevere it is, it does come off when I rubbed a small area with a cotton bud, but that left white flakes floating in the water afterwards.
Any ideas as to what this is? And what to do? Now I have bits of this stuff which I rubbed off being taken into my filter media.
