Drilling a 50gal breeder...

[aquanaz]

I'm looking to drill my 50gal breeder I just wanted to know if i just arbitrarily pick a spot or do I have to drill in certain spots
I'm looking to drill the back glass and trying to keep the holes as high as possible maybe about 3-5 inches from the top of the tank

The closer you get to any edge, the lower the shear point of the glass. I drill 4" OC in corner overflows and the same if I am drilling for a sump 4" above the bottom of the tank.

Gives the glass less room for failure.

do the corner. thats what i did to mine. I guess it makes more sense in my opinion because you are getting closer to the braces for support?

i did mine 4 inches from the top and 5in from the edge.. then used a 90 and a legnth of tube with a screened top to adjust the water level..

this is what i planned on doing, but i was wondering if the line would be quieter at a certain position? tell me if im making sense? i dont want it to sound like a toilet bowl
thanks

keep the flow rate to abt 10 times the gallonage of the tank and you shouldt get that noise.. but i would go with a 700gph pump with a ballvalve on the return side.. valve it down to reduce noise and flow.. and get your water flow form your hydors or mp10.. hope this helps

Mike, Is there a specific law of physics that you're using to determine this? I've never heard of anything remotely close to that so I'm trying to follow your thought process here.

ive always use the 10x rule of thumb for myself.. and then throttle it down to eliminate the noise.. ive never had a problem.

 

[motortrendz]

sorry russ after thinking abt it i guess i should have asked if he was using a sump/fuge.. size of it and as well as the sizes of the bulkheads he was gonna use.. bc it all makes a difference in the amt of flow/ drainage he will be experiencing..

 

[masterswimmer]

Mike, the 10x rule of thumb is acceptable. However, it is just that, a guideline, not a fact.

More importantly though, the 10x rule won't make his system more or less quiet which was his initial question. The efficiency of his plumbing makes all the difference in the world when it comes to the noise coming from it. I've seen low flow, moderate flow and high flow all as noisy as the proverbial toilet he mentioned. I've also seen very high sump flow that was virtually silent.

Oh, and please, no apology necessary. We all are here to learn, and help others.

i never said it was fact... i offered a sugestion that works for me.. its a guide i use as a starting point and as a reference point..

 

[aquanaz]

so pretty much all i need is a valve on the return side and adjust to match the in and out flow a little better, eliminating most of the noise?

 

[motortrendz]

with drilled drains.. what you pump in will flow out.. gravity helps you.. depending on the size of the plumbing and the angles you use it will affect the noise.. but yes once its all up and running i always put a ballvalve on my return side to adjust the flow rate .. look up modified durso system.. itll give you more ideas if you havent drilled the tank yet..
