Hey all! I've had a 10g hex all the time and I'm moving up to a 30g standard size! I need some filter recommendations for it! HOB or canister is fine. the 10g hex has a betta and about a dozen ghost shrimp! Anything else anyone wants to add so I don't forget?
You could go with a Rena XP1 cannister if you want to spend the money. Or you could go with all the suggestions above and get an Aquaclear HOB. I have an AC on every one of my tanks. I have an AC50 on my 29g and you could go with that or the 70 for your 30g.
I have a Magnum 350 and a Millenium 2000 on my 42 gallon hex. The magnum is incredible. It takes a little time when 1st out of the box, but it is easy going afterwards, especially with the quick shut of valves. Flow rate for the money, I think the Magnum is a great deal. I know several people who run Magnums and love them. Of course, I don't have any experience with other cannister filters, but this rookie likes his Magnum.
