Seahorse Tank

[Leah]

Hi,
Yes, I used a sponge and carbon. I have just removed the filter and I am going to see
if I can go without the hang on. I was using an aquaclear 70. I have added another air
stone. But I do have a small remora skimmer. They do not seem to be bothered in the
least by the bubbles. Hope it helps. I will let you know how it goes.
