Re: silicone airline
I have used sillicone air line for some years, but lately I have turned back
to vinyl for filters, because the silicone air line slips of from the air
pump quite easily. Heated vinyl fits better. This has happened to me with
older French Rena pumps - the outlet of older Rena pumps tends to soft
within two - three years. It may be caused by the silicone air line, but I'm
not sure. The newer Renas have a nylon outlet. I havent tried them yet. I
use a safety valve in every pump and this increases the costs - to put the
pump above the tank is not enough because if the air line slips of, it may
fall to the floor with catastrophic results.
If anyone have had these problems with other pumps than Renas old ones, I
would like to know.
In brine shrimp hatching silicone is much better than vinyl.
