What 2nd filter should I get?

The reason the AC's and C's are "better" is you can make your own filter bags (use purigen instead of carbon etc.) because the chemical filtration is just a bag, any bag with "stuff" in it will work, and also it is easy to remove this bag for medical treatments without removing the other mechanical and biological filtration media.
Wow, I had never heard of the Purigen. I just googled it, and I'm impressed. Too bad I already bought a box of activated carbon LOL. I'll have to use it up and get the purigen later.
 
Yes get another 30 gallon rated filter. I run a fluval 406 on my 29 gallon and its rated for 100 gallons. Generally you want to double filter your tank.

Ok, that makes a lot of sense. I shall get another 30 gallon filter. Maybe more depending on my money lol.
 
Id just get an ac 30. I always lube my impeller with a bit of vaseline to help prevent the impeller shaft wearing down.

Ok then, 30 it is! Oh, was the impeller the little spinning fan-like thing? I assume Vaseline is safe for the aquarium?
 
Yes the impeller is the spinny thing. :)

Also, it is safe. Very useful. Reapply every 3 months
 
Yes and make sure to use vaseline on the actual shaft as well. Over time the shaft wears down and leads to a loud high pitch squeal

Does the impeller shaft problem happen on all hob filters? Or is it only the Aquaclear? Should I also use Vaseline on my Marineland filter? I think it has an impeller too.

It wouldnt hurt to slap some on the marineland. Not sure if it commonly happens with all hobs bcuz ive only had acs.

I see, ok. I'll see if I can do some research on it eventually. cx
 
Guys, do you think the aquaclear 110 impeller will fit my aquaclear 70? Or I have to change motor.... Just wondering, if it fit I might get the impeller for in the future.
