[APD] RE: red plants

So, what u guys are saying is in order to get my plants red i should
keep my nitrate at 5 mg/L but increase the rest of my ferts (right now
i add 1.25 ml of kno3, .625 ml of k2so4m .01 ml of kh2po4, and 4 ml of
TMG, 2x per week) and combat the algae i'd get by adding the more
ferts with bigger water changes?

Will the bigger water changes successfully combat the algae? ever
since i got rid of my glosso carpet, algae's started growing on my
Cyperus helferi and it's not pretty.

About the 2 discus, i realize it's a tight fit but it was a suprise
gift, and they seem happy now.

Another thing... i've started to become concern about my heating
setup... right now i use the hydor inline heater to keep my tank at 82
degrees. Should i be concerned that my substrate is probably colder..
or would a hotter substrate be too hot for already stressed
(temperature-wise) plants.

Anyways, totally grateful.. didn't realize that more no3 turns red
plants green....

thanks tom and paul
