I like my water level to the top so when I drilled my 375 gallons I made sure that the overflow box is at the height point at possible
Yeah I wish mine was at the highest point, it's about 1.75" below the brace, so I'm assuming that's the highest I can have it at.
The water in the sump and tank will balance, and you want the water level in the tank just .25 to .5" below your euro brace, not a few inches. But you didn't say anything about your overflow so I assume you have an efficient one.
You have a big tank so you need to plan your flow, both within the tank and from tank to sump. My recommendations are as follows:
-Buy a powerful Variable Speed DC pump for your sump and divide the return to the tank in two. Check out Waveline DC pumps, being able to change the power of the pump will allow you to dial in your flow.
- you likely will still need a Power head style pump inside your tank. Not a Wavemaker, you're not doing a reef. Buy a wide mouth wide flow powerhead or possible two. Between the return from the sump pump and 1 or 2 powerheads create a circular flow in your tank.
To be blunt, it sounds like you're anxious to get the tank stocked before you have the water flow dynamics figured out. It's a big tank, it's important you have plumbing down first!
That sounds almost exactly like the 225 I used to have; same dimensions and all that. I would HIGHLY HIGHLY VERY STRONGLY recommend setting your overflow up for full-siphon/Herbie operation and setting up a dedicated Cerge's reactor running from and back into your sump.
I have attached some pictures of the current set up.
- Using a Octopus Diablo DC Pump, 2773 Gallons per hour, when doing a water test of the tank I had it about 40-50% power.
- Will be going with the Herbie Style for the quiet operation
- I have 2 drain pipes, and 2 return pipes.
- The plan was just to have the CO2 diffuser right next to the intake of the pump, but will look into the Cerge Reactor.
The reason I didn't want any powerheads was honestly because of the wiring, once the cabinets were installed I wanted everything hidden, but I don't think that is going to happen now.
So I guess my question is, where should I position let's say 2 Powerheads, 1 on the bottom left side pointing straight ahead and then 1 on the bottom right pointing at an angle up to push the debris into the overflow?
What are your opinions on the Maxspect Gyre systems, local seller has a XF230 and XF150 for sale, maybe one of those would be enough and provide the right circulation?
Thanks for all the responses, appreciate the help and concern! I am very eager to start stocking plants but no rush due to the rocks not being here for another few weeks. Excuse the dirty glass and the sand, started to clean the sand and had to empty some of it. Scratches are on the black background.
