Well, there I was thinking that I was lucky: Scuttle came with no ink in the bag, didn't ink during acclimation, or overnight first night, or in the morning when lights switched on. But last night (night 2) i came downstairs at 11 o'clock and the tank was black - I mean you could see in about 2 inches and that was it!! I have no idea what caused this, as no one was even in the room. Tank lights were out, but room lights on. I whippe dhim out just in case there was enough in there to suffocate him, popped him into a bucket of clean make up water and whacked the skimme ron full (wet foam) added more fresh caron. After 8 hours the tank only looks half clean now - has anyone an idea of how long it takes to clear a fully inked tank? Also, any tips on getting ink out? I'm visitng an LFS today to see about a cannister filter i can hook up when needed with TONS of carbon. Thanks for any rerplies.
