Now I know the nitrogen cycle and how to do filter maintenance and all the basic stuff. But there's still a thing that baffles me.
When I got into the hobby, I got a TopFin 37-gallon starter kit. (Back then I was clueless on which brand is good or bad) After I a couple of months after setup, the tank was doing good; no leaks, lights and heaters are good. But then I realized the fact that everybody says to change the filter cartridge monthly but it baffled me at the time. I knew what the purpose of it is: to raise BB, trap debris and it contains carbon to remove tannins and odours. I thought that if I changed it, the BB will die. I was right but I changed it anyway and then I did some research and found out that you were only supposed to change it when it falls apart. There is no choice though because the carbon will clog up the filter in a month and the BB lives in the mechanical filtration. That also confused me as when I changed it, the water flow decreased and the filter box overflowed down the sides which tell me that: if I do change it, I kill BB, if I don't change it, the filter basically stops working. It's a hard decision to make.

of course, now I realized that the Topfin filters are poorly designed and the media is cramped together giving you maintenance troubles. I HATE TOP FIN FILTERS!
But it's too late I have it already.

So my idea to solve this problem is to entirely get a new filter.
My first preference was the Marineland penguin bio-wheel power filter 200. (Has separate bio-media that doesn't need to be changed for a couple of years minimum) and has chemical filtration baskets and mechanical filtration cartridges). But then I did some research and found out that the filter was too wide to fit.
so I moved to my second choice, the Fluval C-series. The C-4 was too big, so I settled on the Fluval C-3. I watched a couple of setup videos and it was the first-ever HOB filter to have 5-stage filtration! and was a crossover between a canister and a power filter. Sure enough, it had 2 foam pads (1 coarse and 1 fine) and specified BB living area with bio-tubes and a basket for carbon and ammonia remover (zeo-carb).
This was the BEST filter ever for my tank. It fit the dimensions too.

I haven't bought it yet but I want your advice. Should I get it? The topfin one suck and is giving me lots of troubles and this will definitely reduce maintenance and increase water quality. Don't you think?

Just for me to know... Has anyone actually managed to maintain the Topfin ones? What was your strategy?

If I do (which I probably will), I'll keep both filters running for a couple of weeks to grow the bacteria colony in the new filter and once it's stable, I'll remove the old one.

Heres the Bio media for the C-3

How about an Aquaclear? The 50 should be pretty comparable in size to the C3. The media in the Aquaclear lasts a long time and you just rinse the sponge with tank water. I think these can be found online for about $26 or so. Or just mod your topfin... google Topfin filter mods and see what comes up

So the c3 looks like a good filter. It looks like since they bought out aquaclear the are "up grading/dating" the ac series of filters with this c series. Id say yes go with the c3. The aquaclear ac series has been a go to of mine forever its a great filter. If they have actually improved on it with the c series even better. The only thing I didnt like about the ac series is that mechanical filtration is on the bottom. This c series looks like they make it easy to access without disturbing the biomedia. I'm a big fan of changing the mechanical media out more regularly which is one reason I try to use sumps whenever possible. If you change or clean the mechanical media more often it doesnt have time to rot or cause other issues.

Id say go for the c3 and keep us updated!

So I watched a revjew setup and it really does look interesting. Id deffinately not use the carbon and put more biological in that spot. Here is the review I watched. Didnt realize these have been around for so long but like I said I use sumps....
 
Not familiar with the C series, but have used Aquaclear filters for a long time. I run mine with the sponge and biomedia.
 
Personally been using AC filters since the 80's still a favorite of mine. I don't use activated carbon in non of my filters. I probably would have purchased the C2 or C3 filter honestly never heard of them until now.

I read from a website that the C-series are better than the Aqua-clear. Instead of carbon, I'll use zeo-carb which is a combination of carbon and ammonia remover so it'll be more effective. I might add some bio-media there like
twentyleagues twentyleagues said.

I'm actually heading out to my LFS right now to see if they have it in stock and see what they think of my choice

Also, I have canister filters on my 80G and that seems to be fine and good as ever. It was expensive so I'm not gonna get any canisters for my 37G. My 10g also has a Topin filter, but i'm not too worried as the filter been running for 2 months with no clogs. Probably cuz the tank is sooo lightly stocked and the water quality is good so the carbon isn't working too hard. Should I also get a C-2 for the 10G?
