I now have a better handle on my bigger tank.  The lessons learned have been heart breaking (seeing my 4 clown loaches sucumbed to Ick) and all the dragon tails perish in this little diaster a few months ago.  The water is now crystal clear. 

See the difference?  I got some new decorations and plants.  I now have a couple types of Rainbow and Congo Tetras!  We got rid of the surviving Neons, Tetras and Danio.  We gave them to the school as they have a 90 gallon tank with very little fish.  Hey, it's that or food for the new fish.

Here are the Congo Tetras.  They have a unique shape to the body and the colours are a very nice blue and yellow.  I just got these babys today! 

Along with the Congo Tetras, I also picked up the yellow tail Rainbows.  The great characteristics of these fish are the fact they hang around in plain sight, unlike the German Rams and Clown Loaches. 

Here is what I do differently now.  I vacuum and change about 20% of the water at least once a week.  If I do it twice, the second cleaning is mid-week.  I also clean the filter once every two months.  I have increased the charcoal in the filter, which helps keep the water crystal clear.
