I have a g2 and is been runnning for a while now. No problem so far but the past 3 weeks there is barely any green slim. But I tested nitrate it is still at zero. Do you guys think there is something wrong with my skimmmer? It was tons of bubble when I check. And I already clean the sandra 3500 pump 1 months ago with vinager.
ASM skimmer problem.

It sounds like you need to adjust the height of the output tube some to get more output. Adjust it by twisting the tube and pulling it out. You want the tube a little above the bottom of the tapered area in the skimmer. the bubbles should then be rising up in to the neck of the cup. You need to clean the collection cup every few days as it builds up a coating that inhibits how it works. An old tooth brush with the flexible head works great for this. Hope this helps.
