Snap!! Thats the baseboard looked like pvc!! Disregard lol

Minor observation, I suck at plumbing but looking at height of baffled walls in sump, your drain lines seem as though they would contact water inside the sump.

Never a good idea to have drains at or below sumps water level. You want a clear air gap of a 1- a few inches in event of a power failed its possible to reverse sphion some of your tank water. Just something to consider. How much it could drain depends on where the drains are located in the display tank.

Never had heard this before can you explain it a bit more ? Both my drains are about 6 inches below waterline in sump to reduce noise and bubbles haven’t had an issue with back pressure yet nor any syphoning.. Most all return lines connected to return pumps would be in the same scenario?
I turn my return pump off every 4 or 5 days changing socks which simulates power off plus that would be super easy to syphon out your sump into a higher bucket which never have bothered just use a pump

Maybe it's how my tank is plumbed again no expert. On my over the back return lines on 40gallon tank, I loose power my tank use to drain back into the to sump from return lines.
I've had same issue with reverse sphion with ato reservoir that fell into sumps water.

I was under impression you always want a air gap to prevent reverse sphion.


For my over the back return lines I had to raise them much higher in water column so they are only a inch in control8ng how much can be sphion out. Before they were down 3/4 inches that's how much water was drained out tank

I also never heard of it allowing tank to be quieter my 210nis little bit nosiy but not unbearable. My 40 gallon is slient by comparison.

40gallon has 2 drains while 210gallon has 3 if that somehow makes a difference idk?

Thanks! The gap your leaving from the lines in the sump will not prevent syphoning nor stop it..E.G when you do water changes and syphoning water out of tanks into buckets you can put the water exit line anywhere from bucket to bucket or when it flops out on ur floor it keeps syphoning nothing will stop it unless you lift the hose in the tank out of the tank creating an air gap. Common for people to drill a small hole in return line in tank to allow an air break preventing syphoning into the return chamber of sump.. Now drilling a hole or small cut on the top elbow of the overflow pvc drains prevents an air blockage plus can silence the trickle noise which is a different scenario but good practice depending on your plumbing. Every sump ideally should have plenty of room to handle any extra water syphoned from the tank if not like you said raise your return lines in tank or drill holes up top breaking the syphon. Hope I explained it right not a plumbing expert either but having all girls I say I am an expert unclogging toilets lol..

thats impossible with the eclipse overflow. there's no tube to create a siphon. thats why I drilled the tank

would be possible with the return but ive place it higher than the bottom of baffles. so if power goes out overflow drains it down to where the return is exposed and breaks siphon.

drains are in the sump water to reduce noise and force micro bubbles down.

this isnt my first rodeo plumbing tanks. my previous system and 3 tanks linked to 1 sump

I wouldn't recommend this strategy. While it can potentially stop a siphon, you're playing a game of timing. You have to ensure that enough air gets in the drain to break the vacuum in the siphon before water drains from return line filling the sump. If enough water fills the sump before enough air gets in, you can still potentially have the siphon. It is better to drill a small hole near the top of the plumbing to ensure a constant flow of air can break the siphon. Also, using an external overflow that limits the amount of water that can flow from the tank from the drains lines is a good idea. Making sure return lines are not too low in the tank is another.

Whether there are 2 or 3 drains in the tank, is not the determining factor in noise. It will be determined by 1) air in the drain line and 2) how far water is falling into another body of water (where the source is not submerged). Any small amount of air can create noise. I'm pretty OCD when it comes to tank noise. If you look at this post, this amount of air in the drain line annoys me. Also, on all my tanks, my drain lines are submerged.

Randy’s Flock o' Reef Tanks

So I decided to replace my Reefer 250 with another tank that had a little deeper profile and also an external overflow. Gave me a good 5-6” of back to front space versus the reefer. I had a little bit of a slow start after I needed to get some tank replacements (two). The replacements were...

sump is up and running need to redesign the weir cut out of acrylic on my k40 though. it sits just a tad to high
