Re: Lamotte O2 test

The reason I'm injecting O2 is because I don't have a lot of plants in my
tank.   Actually, I don't want a lot of plants.  However I do want a lot of
fish and I believe some (like parrot cichlids) have died as a result
(little movement and very heavy gill breathing).  So this is a true concern
for me.  I don't use an O2 tank for this.  I choose to do this by running
the tubing from my air pump into my canister filter (using a cheap metering
valve inbetween) rather than just running a plain airstone.  This
eliminates the salt and mineral build up on my glass tops.

Based on your response I don't know how much is 'a lot of plants'.  Not
everyone has a full bore of green healthy stock in their tanks.  You can
have a lot or little amount of plants, but you still don't know where your
O2 level is at, other than seeing that no fishes are dying yet.  And if you
inject O2, there may be even less O2.  How do you know with your current
load of plants that there is enough O2 to handle more fish.  And I am
struggling with some plants as it is, in which case they may do less in
contributing oxygen.

I'd just like to know what range of acceptable tritation tube readings are
for this kit.
