2 simple sump questions

[rtcgibbo]

If you had a 500 gallon with a 2000gal turnover with a overflow this would mean. 2000 gal would be going through your sump every hour and back up to tank. Does the water get slowed down when going through your media? I would imagine it does. Would I need to take this into consideration when setting it up? Anything I would need to change with the flow or anything?.

2. When making a drip plate how do you know how many holes to drill and at what size. Because obviously if the water is not passing through fast enough your going to end up with a wet floor?

Thanks in advance.

That is 1gal / 15 seconds, If your sump has a reasonably large surface area (Based on the size of your aquarium I'd assume you have a large sump) there is no need to worry about your sump overflowing, even if the media or drip tray becomes very clogged. Copy what you see in most applications. (1/4"ish holes every inch or inch and a half?)

I am of the opinion that you should always plan for the worst. It is trivial to provide a path for water to overflow your drip tray safely. Even the most basic designs I have seen provde a gap around the tray or a drain line so that if the tray overflows the water simply bypasses that stage of the filter and safely continues on it's journey.

When I diy my trays with a drill. I started with smaller holes and then tested it in the tank. if it was too slow I made the outter perimeter holes bigger. if it was still too slow, I made the rest of the holes bigger.

If I was not trying to get even flow over the next chamber, I would if drilled 8, one inch holes and been done.
