I think it has been my own fault keeping my water level steady though. _________ 54 quarter corner - nova t5 - 3 mj1200 2 w/hydor flo - dual cpr cs90 - cpr cy192 - css220 - quiet one 3000 - 9w turbo-twist uv - mn404 - Galaxia - Torch - White Star Polyps - Maze Brain - Feather Duster - Mushrooms mated false percs - lawnmower blenny - six-line - firefish - pygmy angel - singapore angel - target mandarin - fire shrimp - arrow crab - tongan fighting conch -tuxedo urchin - sand star - sand cuke |
