Re: [APD] Re: Setting up the Co2 for my tank - thoughts appreciated.

You will probably get more efficient use of CO2 with a
reactor or feeding the CO2 into a canister. If you already
have a canister, then that's the route to go next since it
involves no further purchase.

IF you are going to get a canister partly as a means to
feed water to a reactor, then try jsut feeding CO2 into the
canister first. If that suits you, then you needn't bother
with a reactor.

The basic design of a reactor is relatively simple and
certainly something that can be constructed as a diy
project if you are compfortable working with PVC. A very
good design for a diy canister can be found here, using
parts you should be able to find for few bucks at msot
hardware or plumbing supply stores:


The ebay design you cite appears to use nonrigid tubing for
the main cylinder, which should not matter and has a
clean-out fitting, which also should not matter. You can
clean a reactor by half-filling it with water, shaking,
then flushing with tap water.

Can't speak for "eheim" knock off filters. Looking like an
Eheim doesn't attest to the quality of design or parts. The
Via Aqua canisters have been reported to be reliable and
are much cheaper than Eheims. The Filstar canisters are
reliable and also much cheaper than Eheims.
