It is not so much as adding this or that high tech piece of equipment or
that one needs a ozone or H2O2 dip system to have a nice planted tank. In
well run pearling tanks the Redox is sky high!
Nothing else added. But...................there's also guess what? No algae!

So why add the H2O2? Or O3? Just a good item/tool to use to harass/kill the
algae when it rears its ugly little head. Yet another indicator of tank
health. Wet/drys seem to help this also.
It may be the key to some unanswered questions. Such as why, perhaps, plants
out compete algae for the same available nutrients in a fish tank? Simply
raising/changing the Redox can retard algae growth is all my Dutch friend
said. Just like when we do a water change<g>.

Expensive Redox meters/ozone equipment can be had if you wish but a simple
observational account using something like H2O2 may be enough to convince me
or others that this idea may be deeper than appears. I have a redox meter
laying around and will get to it<g>. Mr Booth's 560mv reading will be a good
standard. I did some DO measurements sometime ago also. I used this as an
indicator for health at one point and perhaps I was on to something but
couldn't put it together back then.
