I hope someone is on here who can answer this relatively quickly. Setting up.our new 40g breeder QT tank this morning. Transferring Clowns into larger tank. Sending some of their existing water and bio sponge from the HOB to the new tank. My problem is that my hob for the new tank is several sizes larger than the one I had on the 13g. Can I put the matrix cubes in that space with the seeded biosponge?
Thanks
Thanks
