I agree with Agu, same sources apply.
We went "down" from a 250 gallon to a 24 gal. AquaPod. After too many years and tanks and all the "stuff, bells and whistles" I can't even remember anymore, I can honestly say we are enjoying this little guy more than any other we have ever had.
I find I use the same sources as I always have. If I have had a good relationship with a vendor in the past, I will choose them first.
Little tanks rock...............good luck and have lots of fun!
