Ok. After spending most of the day sucking some 50g out of my carpet with a carpet cleaner I rented this morning,I want to know if anyone has ever built or hear of a "low water alarm"? Just so I can be woken up in case of a filter malfuction thus saving my fishies, my heater, my floors, my basement, my gamebords, the rental of a carpet cleaner, my time, my money and much...much... much... more DAMMIT! Any ideas are welcome. I got about a week or until my carpets are dry to build one.
