			Jason / Snappy - I have had this sump running for awhile and havent had a problem with the float (even if I did with the current set up it would likely only result in 4 g being added to a total volume of about 90g so it wouldnt do too much damage). How would the float valve fail? It looks like a pretty simple set up with not much that could go wrong. That being said I should look into it before I change something so that I could end up with a 'fresh tank and salt floor'.

			 You could use an air pressure activated style sensor like this Tsunami and then use any container you can get a small powerhead in. I haven't had to touch mine in years and it has never failed. Don't rely on the suction cups though, I made a bracket from a Maxi-jet hanger.
