no it was nitrite... after i added filter woll over the bioballs to reduce the amt of detrius falling on the LR, the nitrite became undetectable and nitrate dropped from abt 100ppm to 25ppm where it's hanging up till now! cannot blame my de-nitrator lar i just added it after abt 4 mths of seeing the nitrate at 25ppm.. haven't tested my nitrate in like 2 weeks actually
hmmm the rainbar works on the water flow... when water flows thru it, it will spin. some science thing.. Centripetal Force or something like that if i remember correctly.. the water will flow and reach the END of the rainbar and the force will cause it to spin.. HOWEVER if the water flow is not strong enough, it won't reach the end of the rainbar so the rainbar won't spin..
