58 Gal: Time off and Growth

I had 3 days of vacation and read Ecology of the Planted Aquarium and Nature Aquarium World I. I got back inspired and worried about the break in the fertilization routine - I want to work on el Natural/NPT/non-CO2 tank and automated dosing.

Here is an indication of the growth rate in this tank. The first picture was taken on 10/5 after I just planted new arrivals.

The second shot was taken just 5 days later on 10/10! Majority of the growth comes from the usual suspects - R.rotundifolia and H.difformis. But look closer at the Echinodorus amazonicus on the right and in the background. Look at where R.macrandra and R.wallichi is.

There are also bad news though. Dwarf hairgrass despite its rapid growth is already covered with algae. Does this ever happen to Amano? I bet he would recommend Caridina japonica. My angels would be sure happy and have it for lunch. Alternatively a fertile substrate might help. Or maybe smaller diameter gravel. Anyway. I am ready to call it quits and look for new (robust, moderately/fast growing) alternatives, e.g. Lilaeopsis brasiliensis (Micro Sword), Hemianthus micranthemoides (Baby tears or Pearlgrass), E. tenellus (Narrow Leaf Chain Sword), Lobelia cardinalis dwarf, Marsilea quadrifolia (fourleaf clover), Glossostigma elatinoides (or just glosso).
