Ok... good enough... I guess its just this cycle which started yesterday and today... STINKY!! So I think that got me thinking about the tops
Also anyone have any tips for a MRC-1 skimmer... I bought it used.. in great condition, running it in my sump with water right to the top of the box (I have the skimmer raised on a couple of pieces of eggcrate.. this is as high as it will go, it hits the bottom of the tank) anyway the gate is fully open... and no matter what I do it seems to put a lot of bubbles/water into the overflow.. filled a orange juice container in about 1 1/2 hrs.. and it looks just like regular water... I had to put a lot of filter foam between the baffles that lead to the return pump do to microbubbles getting into the DT. Anway.. I dont know of any other adjustments other than putting a valve on the mag 12 to the skimmer.. maybe slow the flow a little? I know everyone says these beckets need a lot of pressure... but I dont think lack of bubbles is my problem...
Thanks!
