I've been using some for a year. The only problem I've had us seal
failure around the fancy poly tubing I use. I am switching to small
brass bayonet fittings .... the tubing slides over. I don't think
I've ever had a lid not seal, if it did... I'd just get no pressure to
the tank. That's a pain but no disaster.

For sealing you can also look for a glue called Goop. Comes in different
varieties but Household Goop is the one I use. Good thing about it is it's
one of the few glues that sticks to the plastic these bottles are made of,
it also stays flexible so acts as a sealant. I just drill a hole in the
cap of the juice container (nice big cap which is another advantage), put
the tube in, use the goop to glue/seal, push a little more tube into the
top which pushes the glue into the hole and it's sealed. With the big cap
I actually have two bottles in series. One bottles line goes into the other
bottle (so two holes in that lid) which goes to the canister filter.

Here's a trick for anyone inj into a canister filter. If you are feeding
your CO2 to an intake that's low or near the bottom of your tank, then you
do need lots of pressure and a perfect seal to get the CO2 down that far.
But, if you drill a hole just under the water line in the intake tube (this
is the tube that fits IN your tank and is under water, not the tube that's
outside your tank going down to your filter) to the canister filter and put
your CO2 hose there (a good fit is needed but not airtight), the water flow
will actually create a suction on the hose so you don't need a heavy seal
on your CO2 bottles to make lots of pressure. A good way to remove the
worry of whether your air hose is CO2 permeable and such.

Yesterday my DIY CO2 reactor (coke bottle) fell over and managed to dispense
just under 1/4 of the total mixture in to my tank(tube goes in to Fluval
filter). My wife just called to tell me the aquarium water is a milky white
color and some fish are dead. She indicated that It looked "alive, like
plankton". Is this possible? Perhaps a chain reaction? Help.

Nah, that's the yeast. Some people claim you can feed yeast to daphnia
but that's sure never worked for me. It justmakes a white stringy mess no
matter how litle I use.

A good tip, but as a safe guard I would be placing check valves on the
bottle lines to stop the intake siphoning the bottle contents if a low
pressure situation should arise. OR. use an external bubble counter made of
a 1.25L bottle 50% filled with water to buffer the gas.

When I place my line on a venturi I do this because I don't want the filter
sucking yeast mixture into the tank.

I don't get THAT much suction :P, it would have to be enough to crumple the
plastic of the bottle to get the yeast/suger high enough to be sucked up as
I don't fill my bottles up to the top. Be useful though if for some reason
you get your yeast foaming up which I have heard of, haven't hit it myself
though.

Apparently yeast foams in the absence of Baking Soda. I always add baking
soda and i've never had a head form on the yeast. The mixture just turns
from a dark brown (dissolved raw sugar) to a light tan as it metablolises.

The only problem I have put our seal failure polyethylene pipe tricks I use around. I switched to the small brass bayonet accessories slide the tubing. I do not think I have had a lid not sealed, and if so I just want to get any pressure tank. This is a painful but no disaster.
