My tank temperature was getting way to high. So, I simply succumbed to buying one. Now my temperature is in the low seventies :) . But now i have a couple questions. Whats the best temperature for my tank water to stay at? Also, would it be ok if i added the other actinic light to my tank? or will it still be to much light? Thanks in advanced p.s- These are the only questions i can think of right now but believe me i will i have others ( as i always do) :D .
