Filter max 3 and aquaclear 110 or 70

Just bought the filter max 3 for my aquaclear 70 or 110. Have super naturals black sand and I'm just wondering how good this thing is at catching sand. Really don't want it to hurt my impeller.

Also I can't decide between the 70 or 110 for my 29 gallon. I want to get a banded gourami, tetras, and corys. Is the 110's flow too strong, is it worth the extra cash, or is the 70 good enough?

THANKS.

 

Does the filter suck up the sand? It shouldn't - raise your filter intake if it is, and turn the filter off when you're stirring up sand in the tank.

For a 29 gal, you want between 240 - 300 GPH. I'd go with the AC 70. The AC 110 might be too much.

Sorry misworded my question. I don't have the filter yet. I just got paranoid about the sand and if the cory cats would accidently throw some into the intake.

 

I have never had a problem with that! The cories don't stir up the sand that much.

Thanks for the advise.
