Im pretty sure the overflow will be able to handle the input, which after head loss will should be about 900gph, but the size of the bulkead does have me worried. When I took it in to get it drilled I specified a 2" bulkhead. Unfortunately for whatever reason, I recieved a 1" bulkhead. I didn't have time to discuss the situation when I got the tank back, so I am going to have to call them tomorrow. More than slightly irritated the more I look into my situation. Just glad im in no hurry to get any of this up and running. After I talk with the LFS about what can be done, my pump situation my change. If he doesn't want to re-drill it, im going to try and get store credit to help reduce the cost of buying two pumps, one for return at a lower gph and one for a closed loop manifold.
As for T5HO's, I haven't looked into these that much and I should. I'll probably go over it tonight and compare costs for complete setups, etc.
On another subject, just read an article about the pro's and con's on activated carbon in a back issue of TFH magazine. I had heard many of the same agruments to why people don't use it and why people due. Iv'e come to the conclusion through my own experience that carbon is good stuff to run all the time. Just did a 10% water change on my 20 gal and decided it was time to replace the carbon thats running in the filter as it had been in there for about 4 weeks. Had slacked a bit on up-keep so the tank wasn't so clear and needed a good cleaning/scraping to remove some algae and pesky worms that insist on blocking my view. Anyways, after changing the carbon, the water is crystal clear and looks better than ever. I'll be sure to run it in any tank I keep.
