I just got a macro as100p,and the inlet where the hose which connects to the skimmer inside is leaking small drops of water is coming out of the inlet.how to solve,is there a gurantee for this product?
maybe u should try changing the ballast,bought my dymax t5 from Iw*r*n* and they say they tested ho tubes on dymax,but it would be safer to change the ballast.
yes,its better to have sand as the colonizing bacteria in the deep sand bed(if you have one) helps to convert no3 to nitrogen or ammonium(not quite sure).But its relly up to you whether you want a sandbed.
thanks all for your concern,i am currently using an air driven china brand skimmer,should i upgrade to a macro.if i upgrade would the skimmer help me remove more n03.
