DIY Sump

I hope you have plenty of anti-siphon holes drilled in your return tube!
 
No i dont have anti syphon holes, I used this little one way valve, i put it inbetween the return pump and the tank (so water cant syphon back into the sump) right before the tank....so when the power goes out it just waits to come back on and the pump starts up fine and I dont have to do anything!! The diagram isnt to scale, all in all it can hold almost 5 more gallons before overflowing (the sump) and there isnt a chance (with the valve) of water syphoning back into the sump...and since the overflow is set up to the right level everything is good......trust me...I've had power outages (one last week) and everythings kosher.....:D
 
Sorry to be such a newbie but what is a sump or overflow tank used for and why is it nessessary?
 
what type of silicone used

Hey First post for me

I'm getting a 190 gallon acyrlic tank with 2 over flows going in to 2 ten gallon buckets that are the dry part of my wet/dry filter. I then have two 55 gallon garbage cans for the sump.

My question is I've spent a lot of money so far and I'd like to save some so can I buy 100% silicone from Lowes/HD or shoud I buy the kind that is made for aquariums?

Thanks N8
 
well i bought mine from HD and after i made the sump i read it and it says "for marine use above the water line" so i filled the sump and put some danios in it for a couple days with a small filter on it and they diddnt die...so i assume its ok. Mine was just 100% silicone.

Check valves are very prone to failure. Id still drill anti-siphon holes in the return tube....

Slip, can you point to a thread or web page with a diagram or explanation of anti-siphon holes?
 
its just a small hole drilled in the return pipe from the sump pump, you drill it under the water level just a bit so that if you lose power then all the water wont syphon back into your sump and floor. Dont drill it too far below the water line that it wont break air before your sump over flows, but dont drill it too high that when a little bit of water evaporates that it breaks air.

simple eh?
 
Sounds pretty simple. I take it that the water line you are referring to is in the main tank, not the sump? Oh, and how small a hole? 1/16"?, 1/8"?
