I would watch some of the more sensitive fish species and some shrimps for sure, but I THINK Tom has exceeded these amounts in testing with no real issues.

I wouldn't do this for long though.

Why do you ask?

lol well i dont want to put any trust in my test kits but one reads off the charts for po4 and the other 40-80ppm no3 so... but my cherry shrimp are good and my fish look good so im going to dissmiss the readings. Just wanted to make sure it would not limit any plant growth if it were in fact valid.

I have plenty-o co2 since i crank 6-9bps all day and still have bba growing on my drift wood and some of the older glosso leaves looks burnt/black stuff, guessing bba as well. Just not sure why everything is not totally healthy. Do you guys experience older leaves dieing off?
