pipes/wires running over top of tank

has anyone here got a setup that doesnt have any wires, pipes or anything running over the wall of the tank and into it??

also how many pipes/ wires have you got running over the wall of your tank?

 

all my equipment is in the sump, and I use an MP40W for a power head, so in theory no wires in the tank... but I actually have one K1 that's temporary ... so for right now....

 

i understand that many people will have their equipment in their sumps but what about the return line?? and with the discussion of drilling a hole in the return line to stop the syphon then you must have a line going over the tank rather than a hole drilled

 

Yeah you would need your tank drilled for the return. A lot of times if the bottom of the tank is drilled for your return people use PVC to get over the top of the overflow so it doesn't go over the side of the tank but the overflow wall.

It definitely is possible, just takes some planning and a little bit of cash because you pretty much have to go with vortechs for powerheads.

 

My overflow and return line is drilled on my 30 gallon DT. I run a MP20 so no wires at all. Makes for a very clean look.

 

What about the return line? I have 2 holes in the internal over flow. One goes down to sump, one comes back up to the DT. One side of the over flow has a hole in it for the return ports to go through. It all stays below the top wall of the tank so as not to interfere with the cover (egg crate). Look at the Megaflow over slows, that's what I have.

erm.. I'm not following you here. the hole is actually below the normal water line, in the elbow. It will break a siphon, but not until a few liters of water drain through it. What do you mean by line? Air line? power line? Neither really apply. ... I dunno if you missed a word or some punctuation or something, but your statement doesn't grok.

 

i am talking about thereturn line from the sump to the DT. and what people have been saying is to break the syphon you should drill a hole in the return line so that the syphon will break sooner. but it the return line from the sump to the DT is drilled into the tank then you can really drill a hole into that because it would leak

 

If your really concerned about the back-syphoning from the return line, then just install a check valve. Most drilled tanks have a Droso Drain that has a small hole to break the back syphon.

+1 to this, it doesn't have to be above the water line as it's running, it's actually best IMO to have it just under the water line as it's running, this will eliminate a lot of splashing/salt creep. Just make sure your sump can handle a little extra water, no big deal.

 

... I dunno. I think you're confusing what/where the hole is.

Do you have a drilled tank with holes on the bottom or on the back?

mine is drilled on the bottom, and the "return line" goes from my return pump through a flexible pvc hose to a bulkhead on the bottom of the tank. From there it is a rigid pipe screwed into the top of the bulkhead fitting. The pipe comes up to a 90 degree elbow, and on the inside of that 90 is a small hole. That small hole is normally just barely below the water level of the over flow, which is about an inch below the DT water level. The return line at the 90 splits into 2 Loc-Line positi9onable spouts that I direct through a hole in the overflow wall and into the DT, just below the water line of the DT so as to create surface flow.

yes, it leaks. It leaks very little right back into the over flow. It is not a problem. It's a very small hole. 1/32" maybe?

... I just dont see why there's any confuision. Do you have an internal oveflow with a return or is this just a matte of ove thinking the issue before you have it set up? Once it's installed it will make sense.
