A single 2028 will suffice for a 4ft too.

Hi, it all depends what fishes you plan to keep. If you want to keep 'wast-generator-machine' such as Koi fishes, gold fishes, Pleco & catfishes etc'. These are the very heavy bioload. Therefore you need a fitler at least 4 to 5 times of the water volume of your current tank (i.e 240 litres x 4 = 960 litre, this is the filter you should equip for your tank).Originally Posted by Gambit

Nevertheless, if you end purpose is a planted tank and with a little bioload. The fishes you plan to keep are tetras and small fishes. Then it should be okay to equip with a filter with lower power. My 2 cents thinking..

Thanks for the advice BFG. Btw, why do I need 2 x Eheim Pro II 2026?Originally Posted by BFG
For better circulation ? Wouldn't it be too strong? OR can I just get 1 x Eheim Pro II 2028 instead? Sorry very new in this filter stuff.

My Juwel tank dimension: 121 x 41 x 55cm (240 litres).
Thanks for advice Star-flog. Yeah my juwel tank is mainly a planted tank with a built in power head and filtration system. With mainly small fishes (ie. 16 x Cardinal tetras, 3 x Congo tetras, 3 x SAEs 5 x guppies and 2 x dwarf puffer fishes . After visitng Aquarama over the weekend and drooling over the demonstration done by Eheim Pro III series.Originally Posted by Star-flog
Dunno whether to invest in the external filter system like Eheim Pro II cos I would think the Pro III will be an overkill.Although it is cool system.

Well, for 4ft tank, Eheim Pro II 2028 is more than enough. If you KS a bit, then go for Eheim Pro III 2080, more cool...Originally Posted by Gambit

Well, reason being is that for such tank you need 1 filter to continuously running while you clean the other one. Just a personal preference. I have 3 2026 for 2 of the 3ft that my dad owns and 2 2222 for my mom 2ft shrimp tank. I am a huge Eheim supporter!

Thanks BFG. I see. Wouldn't it be very cluttered with so many filters lying under the tank. As it is, there is 1 CO2 system and 1 chillerOriginally Posted by BFG

So far any complaints for the Eheim Pro II series? How is the priming?
In your opinion is the built-in Juwel filter system sufficient for my current set-up?
You have a chiller in your cabinet?Won't the hot air get recirculated in the cabinet? I do not use the priming function due to the fact that I do not have enough space in the cabinet for me to prime the canister. What I do is to attached the Installation Set from Eheim at the inlet hose. There is an opening in the Installation Set for you to fill it with water. Once the inlet tube is filled with water, you just switch on the canister filter and it start the siphon itself and draw water from the tank. But my tank with cabinet is long gone due to a leak in the silicon joint. But the other tank with Eheim canister filter in my parent house does have the Installation Set especially my Eheim 2222 which do not have a priming function.
Gambit, if you can get a 2026, it will do. A 2028 is better. But it is not necessary to get a brand new Eheim canister as 2nd hand ones are also available sometimes. Just do a thorough check before buying. Another tip to prolong the life of the canister filter. Do not exceed 6ft in length for the hose that is attached to one canister filter.
For your Juwel built in filter, you can place the inlet hose of the canister filter in that compartment as the built-in filter will act as a surface skimmer too. But you need to have enough water in that compartment to prevent the canister filter from running dry. Hope this helps!

Since we're in the topic of filtering, does sump filtering system works well in a planted tank?Originally Posted by Gambit
It would be easy to clean (because it open system) and can maintaince the water level at all time (because sump works as 'reserve tank' under the main tank), no need to top-up water as frequently.
Any comments?![]()

The sump filtering sounds like an interesting idea, anyone using it and is it good?
One disadvantage that I can think of maybe the loss of CO2 due to water turbulence??
Cheers,
Joe

If the pressure hose is placed below water level, it should reduce the water surface turbulence. The only thing that concern me most, is more work involve as compared with just buying an external filter!Originally Posted by baranne

Maybe in 1 of the sump compartment, you could place floating plant eg salvinia or even water hyacinth to absorb the nitrate/nitrite or whatever nutrient in the water. But that would require that you place lighting over that compartment. Some sort of refugium/plenum compartment.

Actually, I was thinking to use it on one of my Pleco tank.Originally Posted by BFG
For Planted tank, the filtering system is not as crucial because most of us just keep very light bio-load. With fully planted tank, the water condition always very clear and clean.

My 4ft Corydoras tank has 2x2028 while the 3ft Plecory tank has 1x2026 + 1x2028.![]()

P-L-E-C-O-R-Y=M-A-N-I-A!!! YEAH!
FLORENCE, capital of the region of Tuscany, has a population of around half a million inhabitants, spreads on the banks of the Arno, between the Adriatic and the Tyrrhenian seas, almost in the middle of the Italian peninsula. It is a city which bustles with industry and craft, commerce and culture, art and science.
Thanks for the advice. Yeah will be getting 1 x 2028 this weekend. At the same time will remove my internal filter and free up some space.Originally Posted by BFG
Is it true the new packaging for Eheim Pro II 2028 has new substrate media in them and it is retailing for around $450 ?
How often do I need to change the filter / substrate media or can I just take it out and wash? Do you need a lot of space to prime the unit?![]()
No my chiller is not in the cabinet, it is next to my tank and well ventilated.![]()

If I recalled correctly, the new promotional pack for Eheim Pro 2028 (incl. all medias + installation set 1 & 2), selling about ~ S$360.Originally Posted by Gambit
