Do the eheim clasics have adjustable flow control? I have my eye on the 2213 and one of my concerns is having adjustable flow control for my betta. If the tank is heavily planted, current may not be a huge issue but i want to have the ability to slow things down as necessary. I see that other eheims have adjustable control BUT, eheims website sucks for good clear info so i figured i would ask you guys.

Also, how is the ecco series. I like the classics series because the water is forced to go through all the media, top to bottom where as all the other models eheim offers have both inlet and outlet on the canister top.

I went to a lfs the other day and i was talking to the guy and he suggested the classic series, hence the question above and i forgot to ask him about the flow control, hence the question above again. Well aside from that, he also suggested that i get a HOB as well to keep the water clearer. He said the canister is great for filtering and cultering the good bacteria and he said a HOB would help alot with clarity because of the larger flow. I think it would be a good idea and was thinking of just packing a bunch of carbon filters in the HOB because carbon does wonders for filtration and clarity.

Thoughts?
 
Its possible to add your own valve to the plumbing.

But a number of things come to mind.
1. Bettas do like slightly calmer waters, but they can get used to strong currents. Though it wouldn't hurt to add a few "calmer" sections in the tank by rocks and driftwood. I have a Magnum 350 on a 29g, overfiltered? maybe. But the bettas don't seem to care, in fact a couple will surf the current every once in a while.

2. If you like that design, Marineland makes their Magnum filters in much the same fashion, but much cheaper, and more bang for your buck. Remember, you can never have to much filtration. Plus Micron filters :grinyes: , And for some bio-media, add a Filstar foam pad or two in the canister. Thats been my solution, and I'm running the micron 24/7. Oh, and for added convenience, The Mag 350 comes with double valve quick disconnects, and both hoses come from the top (but still works the same as the Ehiem classics) .

3. Ehiem classics have a much lower turnover rate than MOST canisters. If you notice, the 2213 only has a flow rate of 116 GPH, The biggest I would put that on is a 20g, and if you did put it on a 20g, you wouldn't need to reduce the flow any. And the betta would easily get itself accustomed to the flow.

4. Canister can have carbon in them, no need for an HOB as well, although, again, no such thing as too much filtration.

5. I and many others don't run carbon, mainly because we have to replace it so often. Yes it offers much greater clarity, but its not absolutely needed.

6. No matter your choice, your best place to purchase your filter would be here

Just curious, how big is your tank?
 
I am pretty set on the eheim canisters, i read a ****ton more bad reviews on the marineland canisters with o-ring failure and alot of just plain disappointment. I suppose it could happen to any canister but alot of ppl that i have talked to swear by eheim. Drfosters is a great website, alot of detailed info and what not, makes me feel comfortable as a consumer.

I am aiming for a tank turnover rate of atleast 4 times and o itll be between the 2213 and the next one up a size. If need be ill buy the big boy because i can always adjust the flow. I didnt realize carbon was such an issue all the time to have to change. I read the eheim classic is a bit of a ***** to prime and to chnage relatively often, i might just do a seperate HOB carbon thing i think. For that, i just need a cheapy filter system or something that i can customize to make an easy to chnage carbon system. I am just looking to be able to buy the bottles of activated carbon so that i can change it easily.

I actually did a water project on purification in 6th grade. Our treatment plant is next to the bext in the entire U.S. and part of it was visiting them. I did the multimethod of cleaning that they do and one of the legs was carbon filtering. I use the ube dirty water from the hackensack river (notoriously known for being dirty now) and it was NASTY. The plant used sand, activated carbon, and a pebble like substrate to filter if i remember correctly. This is just a nostolgic thing for me now i guess haha.

If i bought a water pump with some low flow and just made a tube of carbon or ghetto made a HOB, would that work good you think?
 
If you just want something to run carbon in, a cheap HOB would do the job, and probably be easier, more effective and cheaper than trying to fashion something yourself. Changing the carbon is not a big deal, it just has to be done every few weeks to maintain effectiveness.
 
The mag 350 is a loud noisy pos for continuous use with almost no room for media.
It does well a a "quick polisher" though.
Eheim classics may not have the flow that others do but they hold more media than most
and actually come with all the needed media for immediate use.
The best filter possibly ever made.
Super quiet, no bypass and very customizable. Some people have theirs for 20-30 years with no major problems.
Can you say that with any other cannister brand out?
