First time sump ?

[cyris69]

Ok, so I use a 75gallon tank for my 5 pyxie frogs. They have a 2' long by 9" tall water area.

I have two large canister filters ion use for the water area since these are some messy frogs

I just bought a rio+ 2500 sump pump since it was on sale for 40$.

My question is can I use the canister filters as pumps (remove media) to take water from frog tank to sump tank and that pump from sump to the frog tank?

I'm going to use either my spare 20L or 10gal for a container for a DIY wet/dry

I have the idea in my head but was wondering if it's feasible with such a low water lever to begin with.

Normal aquarium sumps draw water on gravity through an overflow box that flows to replace removed water by exit pump. If pump stops (breaks or power loss) the flow will also stop because there is no "overflow" in main tank.

In your system you describe active pumps (canisters) providing the input flow. If the return flow pump fails... you will flood the sump and then whatever floor space that tank is (unless you use a huge sump that can accomodate the whole volume). The two canister pumps will run all available water out and then run dry until they overheat and shut down or worse.

10 gallons of water do not seem like much... until they are in your floor . Just running you through some possible nightmare scenarios .

Yeah already had a wonderful 900gph spill

How can I do a gravity siphon with such shallow water? If I was able to even pull it off how big or a tube would i need for the gravity siphon?
It's tempered glass so I can't drill holes in teh bottom and wouldnt trust myself to do it either. THere are two 3" holes drilled on the back glass about 6-8" down from the top

I did tweak the output from the sump to keep it steady but still wasn't stable enough to use.

Appears at a time your tank was rigged with some accessory, maybe an overflow. You can't drill bottom and you can't drill close to edges on back or sides. If you have a local pet shop with nice marine section head up there and try to get help selecting an overflow box that you would adapt to low water by drilling needed holes at a low level so that it works in your set-up.

All this would be a custom fabrication/experimental design so... measure 3 times, drill once, and hope for the best. Also, the overflow box gets water from top, which might not remove heavy on bottom sediment contrary to a canister with intake located close to bottom. Each overflow box comes with joints able to flow it's recommended max flow rate.

If you search "aquarium sumps" in Google or YouTube might come to some designs that could adapt to your needs. A 75 gal. is OK for an adult GABF; but 5 is just too much for the tank and any filter system you can connect to it. The sump (if workable) will help by adding water volume; but think that eventually (if not now) the tank will be overcrowded to point it creates you problems... just saying .

Yeah the dwarf and two female frogs are going to a 40g breeder tank since they are considerably more docile than the two males which have become quite aggressive eaters.

I was hoping to do the sump and transfer this weekend.

Thanks for the help! I guess I will just have a really efficient water changer
