2.5 gallon ruge on 2 gallon deco

[ilostnemo]

so today i bought a 2.5 gallon tank with light. i was going to use it for a refuge for my deco but i cant decide if i want the 2.5 as my dt or my refuge. any thoughts? also how could i make a overflow for something that small? or could i just use two pumps of exactly the same flow rate and it be ok? i generally know using to pumps is a bad idea but i was just wondering about this?

Badddd Idea. Very very bad. Even if two pumps are rated with the same GPH they in reality will have very different gph. On such a small tank a difference in a fractional GPH can mean an empty tank and water all over floor.
Why don't you just take a glass cutter and cut a small rectangle and partition it off with some mesh along the edge of one side of a tank and then silicone the other tank to it. Only one tank would actually contain a pump. it would pump into the cut tank and then overflow back.

You could probably super glue a small spill way to make sure all the water gets into the return tank.

hmmm i didnt think of that crepe. thats a good idea. only bad thing is one tanks glass ones acrylic

if they have flat edges, put those together and elevate the one you will use as a fuge slightly, then use 1 pump to pump water out of the main tank and into the fuge, then cut out a section on the fuge so it overflows back into the DT. Does that make sense?

the 2.5 is flat and the 2 is the tom deco kit and is kinda curved. and yeah i get what you mean. i was thinking having the dt run into the fuge then pump into the dt. im just not sure if there would be any differences between which tank has the pump

 

[Jimbo7]

if the pump ever failed, whatever tank has the overflow will lose water, so depending on where you put the overflow/drain, you could lose an inch or so of water.

its not a huge deal, but I know in my pico, i had to use every bit of space I could, and there was lots of stuff up towards the top I wouldn't want to come out of the water.

alright thanks jimbo. so i decided on pumping into the dt and overflow into the fuge/trickle. i know its gonna be small area but itll be alot better then the tiny hob filter
