Overflow looks great. No experience with a design like that but my only concern (you mention it as well but seem comfortable it's not an issue) is that the flow rate on your return pump sets the waterline at a point that give you good surface skimming. If your return pump flow rate can be tweaked slightly (if that proves necessary to get good surface skimming) it shouldn't be a problem. Depending on the size of the gap in those slot, you may get some travelers from the display to your sump. Who made the overflow for u?
Nice tank and lights!
Really clean looking tank.
I dont really understand the purpose of the horizontal slits. Looking at the pictures, it seems it is taking in water from the first and second slit. If that is the case, you are not surface skimming as much as you could/should be. I think the overflow looks really great but for my tank I would rather have a great surface skim then a trick looking overflow. I think you could just cut off the top slits and make a weir design that would look great still and give you better surface skimming. You could always make a cover if you were concerned with fish and snails going over. Also, are the magnets giving you a complete seal against the glass? If so, great idea.
Overall a great looking setup.
Just noticed, is there no foam under the tank?
Wow that overflow box looks awesome / nice and clean.
Great tank. I love that you have been so good about keeping us updated on everything.
very nice lighting..
Wow awesome build!
Calvin,
FWIW I remember a poster who had great success with check valves. It was a commercial venture out in the middle of nowhere that had two or three short power outages daily. The outages flushed the valves and kept them in good working order.
Not sure how you can "flush" a valve by killing power, that will only test it...
I think hes trying to say that it will cycle it, allow it to move. That way Ca and gunk doesn't build up and stop it from working.
The tank looks great. Crystal clear.
