New HOB filter
Well after discussing on the forums, I got to know that canister filters are the best and HOB filters are the next best. So I got myself a HOB filter. My LFS had only one brand called Dolphin (I guess chinese make) and its rater for 210 G/hr. My tank is a 30G tank. Is this ok? I have a 300G/hr internal power filter in this tank and I just some additional filteration because I am going to stock cichlids.

They rate filters' GPH with no media in them and in lab conditions, so the actual GPH is about 30 percent less. What Cichlids are you planning to keep?

I am planning a pair of convict cichlids in 30G (may be with some corys) Current media in filter is only a rack of sponge and a rack with carbon, but I am planning to add more, I have the space for more... may be ceramic rings??? I donno how to find them. My LFS has no more media! :)

30% less means ~150 G/hr and at max flow rate I suppose. (there is a knob on the inlet pipe to adjust the flow rate)

if the convicts spawn the cories will be killed.
also, carbon is not needed, i would just use the sponge, and ceramic rings

at present the carbon is filled inside one of the media trays that came with the filter, I will need to tear open the pouch to get the carbon out.

I disagree that HOBs are second rate to canisters! I think they're a better choice for smaller tanks...55 g Goldfish Tank - 5 Fancies, 2 Dojos
25 g Tropical Tank - Celestial Pearl Danio/Mixed

i still see them as second, all of my tanks besides my 55g reef have a canister (enough live rock to filter). canisters force the water through the media while HOB's just let it flow through

I dont know.....although I'm inclined to believe the canisters are better
