How can I make a 1 gallon sump for a standard 2.5g AGA tank. I have a 1g tank that I was planning using. I don't want to drill or anything. What will I need??

overflow box, bulkhead and return pump

Thanks. I'll look all that up

is there anywhere i can buy a small setup like that?

I doubt it, You'll probably have to get them (most overflow boxes come with bulkheads already) and then put it together yourself. Try looking around though chances are none one is selling a 1g sump. you might also want to look into to putting some baffling up to prevent sand from messing up the return pump

Ok. I'm still a n00b with all this DIy stuff.

So anymore ideas? How much would the idea already said cost??

for a tank this small, drilling may be your best option. You have to worry about breaking the glass though. A HOB overflow would take up a lot of space in such a small tank.

you could use a back to back approach, where the tanks are touching back to back with an over the wall U-tube type thing?? lol

Your best bet is to partition the tank and setup a false back wall with in-tank sump behind it.

ive already built this tank into an aio lol

That's what I did with mine, except with two 2.5G's, and a return pump in the back tank. Worked great for two years without issue.

then you have a 3.5 gal keep it simple

i would look toward a cpr style overflow. they are relatively slim in design and work quite well. then as a sump look around your local hardware store for a rubbermaid container of some sort.

im done with this tank!!!!!! lol i broke it. im getting my 14g wednesday though. go check it out in the all in one section!!!

I would recommend using a continuous siphon overflow, and making the sump much larger, say about 10 gallons. This would allow you to have a refugium, which would be uber beneficial for your system. A 1 or 2 gallon sump really wouldn't have much impact, but a 10 gallon would. You could easily quadruple your water volume, and add an ATO to the sump, store the heater, put more LR in there, a deep sandbed, chaeto, caulerpa, the possiblities are endless the bigger you go. Sumps are great. Don't be afraid to go big!

not being a jerk but can yall read? lol i broke this tank lol
