One slight niggling worry I have. Are all the materials mentioned,
safe for use with aquatic life?

The plastics used are commonly used in commercial filters, and obviously the
brushes and fittings are supplied by aquatics specialists, so are safe. The
adhesive is sealed by silicone sealant, so should not be exposed to the
water, and the sealant, once completely dry, is inert, so should present no
problems to aquatic life. The important thing is to make sure the sealant
is completely dry before installation as it contains ammonia, which is toxic
to fish, but this is driven off in the curing process. I should perhaps put
in a recommendation to leave it 24 hours before installatiuon to be
completely sure.

As a further addition to this, I have noted that some general purpose
sealants do say 'not suitable for continuous submersion' and therefore I
have changed the site to specifically recommend marine or aquarium silicone
sealant (which is effectively the same stuff, just with better adhesion).

It's spam. It does advertise and recommend at least 2 commercially
available products


So, it's OK to have a website showing you how to make a cheap pre-filter
for a pond, so long as you don't tell people where they can buy the bits
to do it?
I can only assume:
a) Troll
b) seriously sad life

You need a holiday ( a very long one!)

Hi Jason,
I found your page very informative and most helpful.
I searched high and low to find a cheap pre filter and how one could be constructed.

Thanks
