Interesting read. I was looking at getting my aquasafe treatment and it came bundled with this product for a good price. I wasn't sure if it was workable. After reading the whole thread I might see a use for it for the occasional planned missed water change, one example being going on holiday. I can't see me paying that much for it but on the other hand it is only me who does the water changes in our house as the kids are too young and the mrs isn't tall enough.
I now have the same issue lol didnt take into account when buying the trigon that the mrs couldnt reach inside (dreading the day she falls from the step ladder and i return home from work to find her scuba in the tank without a snorkle hehehe)............ Wait up there's food for thought
