I have been using Tropica Mastergrow for about 6 months. At first
I used it in just one of my tanks while I continued to use the
Dupla fertilizers in my other tanks. I have become convinced that
at least in my tanks, the Tropica fertilizer works at least as
well, and has the added advantage that it is added once a week
with water changes rather than having to remember daily drops.

It is perfectly possible to have good growth and not see )2
pearling. You will only see O2 bubbles when the O2 content in the
tank exceeds saturation. A heavy fish load, among other things
can prevent the O2 from climbing high enough to see pearling. If
your plants are growing well, don't worry about it.

Sorry, you'll have to explain further. What's an "MV reading"?
