Sponge Filter?

[KingofthePisces]

so i recently aquired an old sponge filter (i think) its in good condition apart from some calcified stuff on itbut i think theres somthing missing in it i know the sponge from the center is missing but when i first got a look at it there were small carbon pellets in the bottom. are these neccessary?
this is all i have:

I personally wouldn't say carbon is vital in any filter unless you are cleaning up after a course of treatment.


You will need an air pump to run that filter though and you should select the appropriate sized pump depending on how big your tank is.

i have a pump and a heater too.
so i need to buy some carbon and a sponge for the empty void in the middle
i actually got it for a frog and fish tank and that brings me to my next question.
the tank is a 2 ft long 25 gallon tank
how much ground will the tree frogs need?

im stocking it with 1 or 2 whites tree frog(s)


EDIT: im going to make the ground part rock/slate stacked up on top of each other sealed together with silicone
i have all the tools and neccessary aquarium itemsall i need is the silicone, slate, the rest of the sponge filter and water pump for the waterfall that will trickle down it

The filter is called a box filter and can have sponge, filter wool/floss, carbon, or ceramic beads/ noodles in. Most people use a sponge because it lasts longer and traps the dirt. Then it can be cleaned in a bucket of tank water.
You usually have a layer of marbles or course gravel on the bottom to hold the filter down and prevent it floating around the tank.
There is an extra piece that doesn't belong to the box filter. It is the top right item that looks like an elbow. That bit belongs to an undergravel filter and is not used on the box filter.

If you are keeping tree frogs than they don't need much water. Most people have a shallow bowl in their tank and let them splash about in that. They also use a plant sprayer and mist the tank once or twice a day. Tree frogs live in trees and only go to ponds to breed.

I agree. But I wonder if the OP is hoping to have an ecosystem in his tank.

It would be great if KingofthePisces could put some pictures (photos or diagrams) of what is going to be built.

If the intention is to have tree frogs living on a island in the middle of the tank, then there needs to be a lot of height of plant matter above the water. So not a tank with a lid. I dont think it would be suitable to have just a few twigs and branches above the water line. These frogs like thick green growth and plenty of space around. Plus they need some places to catch crickets/flies for their dinner.

Just "googled" tree frogs. Have a look at some reptile websites. They say Tree frogs need space for climbing. And because of humidity requirements the house should have a lid.

sure ill take photos of when im making it

i was thinking some logs and branches instead of plants but i may have some plants to replace the oxygen in the tank (any sugguestions for small plants?) otherwise i can just put mesh over one half and glass over the other to ventilate it out.

so far ive got the following equipment:
air pump
fish tank, 25gal
small heater, aquatic
small box filter
gravel (for fish part)
some logs
possibly the pump (checking tomorrow)

missing:
a lid for the tank
some logs & branches
plants
slate & rock
(anything im missing?)


the plan so far is to have a small stream (im making this out of thin aquatic safe platsic to aid cleaning and sealing all the parts together with silicone (would a hot glue gun be better for the rocks?) edged by stones falling down the rocks into a small pond which continues into around a 5 - 10 gallon small pond at the bottom (stocking of this is still to be looked over) plants will possibly be some mosses and mabey some short broad leafed plants for the frogs as well as some logs that will be partially submerged. this isnt going to be fixed into the aquaruim (just in case i have to change it back) but it is going to be an island of mainly a small stream and pond.
