If you feel you are not processing the expected the flow rate with a Durso Standpipe installed said:Has anyone done this before? How do you know if it's "processing" enough. [smilie=smile.gif]
During testing I did notice that when I cover the whole on the standpipe the water level in the overlflow drops and when I let go it the water rises and stops the gurgle for a few short seconds (not sure what that means). said:That normal for when you cover/uncover the standpipe. It could point to the hole size not being quite the right size.... the hole size is dependent on drain length. It may sound strange but can you try running a piece of airline tubing from the hole in the top to about 4-6" in length down the drain to see if that changes anything. Looking at the flow specs for your pump and assuming 3-4 ft of head pressure then you may be at the hairy edge. You can try to throttle the pump back a little to see if it helps.

Cheers,
Those are good reads Bill. I too made the mistake of poor planning and execution on the aquascaping. I'm dealing with it every time I look at my tank now. I'd love to go back and re-do it said:We've all been a beginner once... Here's my very first tank with the "fruit stand" aquascape (2004):
Holy smokes. That's wild. I have 2 pieces of dry rock that is really white and I'm sure it was bleached before I got it. I should do that with the remaining rock that I have. said:One of the best perks of dipping the rock in acid was the removal of the outer layer and exposing the inside of the rock. Some of the rocks that looked solid on the outside now have caves and cracks that you couldn't see before. Plus they all have new characteristic's because all of the rocks had different coral skeletons in the past.
