Reefdepot used to carry them but think they have stop bringing in because they are rather brittle and crack easily. 1 ft tank is rather small and if noise is an issue, maybe you will have to consider those skimmer running on air pump ....think you will need to get the sander wood to run it effectively. If not, you can try go to iwarna to check, they do have one skimmer ###### filter hang on device.. ..not sure the effectiveness but for 1 ft, i think regular water change will be good....for the noise level, unless your office is very quiet, if not, it is still bearable with proper maintenance....
