OVERFLOW PROBLEM
OVERFLOW PROBLEM
Thanks Snowboarda42 for the suggestion. I tried from different size holes to different shape holes but just not draining fast enough due to the powerful return pump..
Anyway, finally decided to used a different method...
Updates as below:
Got right to it to revised my HGB drain pipe yesterday and fix the extension onto my wavebox… after tweaking with the drain pipe and trying with different size holes, it just doesn’t drain fast enough due to my powerful return pump. I finally revised my HGB to a ‘Herbie method’ fine with the level of the water about 1†above the edge of the drainpipe and now it works fine…. Total silent. :rollface:
However, still need to section off the drainpipe area to limited the water drained to the drainpipe area during power off, or it will drain too much water into my sump and overflow from my skimmer…. Alternatively is to raise my skimmer and redo the piping of my skimmer output into the sump but I would like to avoid this…!!
Revised Herbie Method drain pipe:
My wavebox ‘extension’ is also done…. Hopefully it works….will test it out once I have the 2 glass panel glue in my overflow….
With the add volume of water in the wavebox, it should create a bigger wave… maybe??
one tried this before?
Now I have to drain the tank in order to glue the 2-glass panel at my overflow.
Actually not too bad as it will only be in the tank when needed....
