Volume Math

Hey Beverly
Just to let you know that it's not just the saltwater that breaks down the silicon. Other factors come in to play such as; moving tanks, wear and tear from sand and abrassive rocks, and the number one cause(so I was told) is from passing cleaning magnets to the edges or over the corners of the silicone

That's kinda funny now that I work out the math, once a wekk cleaning over 7 years= 362 passes over or beside the silicone-now I can see why they rate there tanks for 10 years

Here is some of the email sent to me by the folks at Hagen:

All things being equal your aquarium should last for ten to fifteen years. Or, said differently, at ten years you should begin considering replacing your tank and start looking for sales, as it is around this time that the silicon begins to tire.
