Thanks. The pump i'm using is the same pump I used for my chiller in my previous 90 gallon tank but it function as the sole return for the tank. Now I want to use it with the 125 that already has two built in returns with the mag 18, and the pump with the chiller would be an additional 3rd return using the flex tubing thats either 1/2 or 3/4 inch.

If tapping into my existing PVC return plumbing is not an option could I put a second pump in the return section of my sump that feeds into my chiller using flex piping that then returns cool water into the display as an additional return? I read that additional return pumps are used as backup and or for UV so I wanted to do the same with my chiller using all flex tubing.

Thanks a lot!!!

Thanks. yeah, i've done a few power outage tests so it won't happen in the sump. I just didn't know if the skimmer pump sucks in more gunk at a much lower level or higher level. I remember reading something where skimmers perform better at a certain level in the tank but I wasn't sure.

the water level is not. Just the angle of the picture. I have about 6 inches of height above the top of the baffle. After a power outage, water level goes up 2 inches.

Thanks for any response.

I should have took a picture of the return side but there are no bubbles forming in the return side when it spills over to that section. I was just curious about bubbles from the waterfall effect in the middle compartment.

No i'm not getting rid of the baffles. What herd?

That's not the last chamber. That is the middle chamber(refugium) than after that the return chamber.

I'm running my leak test again on my sump. Everything is fine now. But after the water goes through the three baffles, the water waterfalls into what will be the refugium. From the image posted are those bubbles considered micro bubbles or I shouldn't worry about the bubbles formed from the waterfall? Thanks

Thanks a lot guys. I went to the glass company and they cut my baffle down 4 inches, so its 11 inches high on the return side. They cut it for Free!!. So I will make the chamber wider which will cut my refugium down in size. Do you guys think my skimmer chamber is too big? I was just thinking of removing all the baffles and making the skimmer chamber smaller just to fit the skimmer and have the refugium and return chamber larger. I will also flip the sump around and pump the pump chamber closer to the wall. Also any more suggestions on my leak problem under my left overflow where my ball valve is located?

When I cut the power the water level rose to half the chamber where I put the blue tape where the pump is located. So could I add more water if the water rose only that much or will it raise the water level in the display tank?

I'm using tap water during the water test so I will be emptying out the tank and sump. 1. You can see the picture with the sump and I have a mag 18 pump but the water remains low where my pump is. Is this because the baffle is too high? What should I do/ 2. I have one leak with the whole setup. under my left overflow you can see below my ball valve there is a leak. God this would suck if I have to cut everything out and re-glue. Is there an easier way. Would some aquarium silicone be enough to block the leak?

What I don't get with the baffles is the 1 Inch spacing between the 3 baffles that everyone says it has to be for microbubbles. I cannot even get the silicon tube the fit a little bit in the 1 inch gap to even get started. How is it possible to silicone this properly, especially with the middle baffle. Does it really need to be only 1 inch spacing? There has to be a better way.

I'm at the stage of installing my glass baffles in my glass sump tank. I put the first one in to cure for 24 hours and I will do a water test tonight. Question: If there is a leak, do you just overlay another layer of silicone? Will that be sufficient?

- I'm trying to get all my inflow to the tank from the return pump. - All going to the display from the return. No split except for the tee that negotiates between the left overflow and the right overflow - Do I need or want that much overflow? I don't know? John at Blue Ribbon Koi suggested a Mag 18 based on what I described at the beginning of the post. - If you are concerned about 1000 gallons are you suggesting Mag 12? - throttling? I do have the ball valves at each return, I have pic posted What do you think?

hmm. I have a chiller if the heat gets that bad. I'm just concerned about my horizontal length that I mentioned in the start of the post along with upflow and the water negotiation at my Tee and I don't know if that Eheim 1262 will be enough compared to the Mag 18.

What submersibles do you like? I've been reading about noise for the mag even though mine will not be under my tank but in a separate location.

On the Mag 18 the calculations come out to, Total losses are 6.91 feet of head pressure, or 2.99 PSI. with a flow rate of 1089 GPH Are those good numbers?

Yeah, I was looking for a submersible because I don't want to drill a hole in the side of my sump for an external pump and yes the cost too.

Which model? How many GPH should I look for?

I need to make sure I buy the correct pump. I have a 125 gallon with 2 overflows. 1 in each corner. the return pipe is 1 1/2 hard PVC. My return will be pumping up from the 21 inch high sump, moving the water horizontally across the sump 4 feet, than another 2 or 3 feet before hitting a Tee that feeds up my return on the right side of the tank. Also moving another 6 feet to the left side of the tank and elbows up to the return on the left side of the tank. Thanks

No worries I took a drive to Blue Ribbon Koi and we mapped out the best solution for plumbing. I'll let you know how it comes out. Sorry for the confusion.

So are you saying, the existing 1 1/2 inch pvc pipe in my overflows should, via the bulkhead convert to a 1 inch horizontal pvc that runs horizontal to my sump? And my exiting 1 inch return that sits inside the overflow should me merged from a 1 1/4 pvc? I'm about to go to lows and I want to be sure I got this right. Thanks.

Well I emailed yesterday and called twice today. So far no response.
