Help with the calculators

I tried to use the calculators to determine the amount of water I will drain and return. My question is I have corner overflows therefore I have two drain lines and return lines. Do I insert the smallest diameter of pipe and multiply the result by two? Or do I multiply the smallest diameter by 2 and insert that number for the calculations.

The smallest diameter for my return lines is 3/4"
The smallest diameter for my drain is 1"

I am buying the Jabeo DCT12000. It advertises 12000 liters per hour.

Also my display is 72" long x 24" wide x 30" deep which I believe is 210 gallons. Will a 40 breeder be enough of a sump. I am thinking socks and a skimmer later. I do have marine pure to put in the sump.

Thanks D Smack. Do you have any suggestions on the making the 40b a sump. I have glass to make the baffling.

I think it depends on what you plan on doing with the sump. Is your skimmer internal or external? Do you want a section of it to be a refugium? What other equipment are you wanting to put in there?

I have the same size tank as you do. I use a 75g as a sump. Lots of room and it fits well under the tank if you need to put it in the stand.

I will look for a 75g. Do you have two 1" drain lines and two 3/4" returns? If so how much water will drain with 2" of water above the drain line? I used the calculator but I wasn't sure how to input two 1" lines.

If I'm understanding your question it has nothing to do with the size of your drains. It has to do with the volume of water that your aquarium holds above the drain. So 72"by 24" by in guessing like 2". Plug that into an aquarium calculator and you know how many gallons will drain down.

I didn't convey my question properly. What I am trying to determine is how many gallons per hour my system will turn over. If I buy the largest pump money can buy, I will deplete the water in my sump because it will pump water out faster than the drain lines can drain water. So with two 1" drain lines, how many gallons per hour will be turned over?

Google how much water can flow down the type and size drain you have.

600 gph for 1" drain pipe. So I have two so I should in theory drain about 1200 per hour. That just seems really high to me. But I can only assume it's correct.

I'm not sure what your trying to get at here. Are you looking for a recommendation on how many gph you should try to get. Possibly a turnover ratio?

I'm in the process of setting up a 280. I'm looking for about 2000 gph using 3 drain lines valves, 1.5 inches to a 55 gallon sump. So approximately 7 times turnover.

I doubt your overflows would handle that much flow.

I agree. I don't know what I am doing wrong with the calculator. I inserted 600 in the blank box and it said 1" pipe. That's why I started this thread to begin with. I found the calculators and the results I received seemed off. It is apparent that I need more time surfing the google machine and the enterwebs before I buy my equipment. The holes are drilled in the bottom so 1" is the largest pipe I can use for drains with the bulkheads. 3/4" is the size of the return pipes. I don't know what I am doing wrong with the calculators on reefcentral, but apparently I haven't mastered the art of inputting numerical values in a text box. In all seriousness, I truelly don't know what I am doing wrong. I am sure it is something small that I am over looking. Thanks for your help everyone. I am embarrassed of my denseness.
 
Which calculation are you getting to do and why. Buy a pump that flows what you want. With your tank draining into your sump the only way you'll run out of water is if you don't have enough in the system.

I just wanted to know how many times the water will turn over in an hour. I guess that isn't as important as I am making it out to be. I will buy a DC pump that will flow more than I need and control the speed of flow. I am making this way harder than I should I guess. I get a bit nervous that I will spend money on something foolishly because I didn't research enough. Like I did with my BC29.

I will be buying a Jebao 15000 for $135. It has good reviews on both amazon and here on reefcentral. I will shift focus on the sump so I can get some water into this tank. I hope to have it cycling by NYE. I have some rock and sand, plumbing and that's it. I still need a 300 watt heater (any suggestions), sump (40b or a 75g). I have some lights I will put on for now but I will be upgrading them before we introduce coral. Later I will get a skimmer and an ATO.

Thanks for your help. I hope I didn't give you a headache.

Finnex titanium and I use thier stand alone controller. I would have double redundancy on things like heaters.
