I am VERY experienced in fw, but have never had a sw tank. I have decided to make a 1/2 gallon pico (some of you might recognise me from my build thread)
My question is, would it be fine to have a sponge in it. I know there hard but after seeing them, I have fallen in love with them. I just want to know if its a good idea, I will add coral on this Saturday, so I decided to ask before getting it.
