Small yet powerful

[instinctloh]

Hi,

my uncle just gave me a spoilt canister and I intend to use it with the help of a power head (not sure if is the correct term) basically I need a small yet powerful pump to push the water into the canister and back to my 2ft tank. Any recommendations? If I'm not wrong the canister is the ehiem 2213. Basically all the internal part is removed so is now left with the trays and the housing only.

Wondering is there such and small powerpump tat can do tis job?

wondering if I can do some modification work and put the pump in the canister instead of in the tank?

thks

it's possible to modify a eheim 22xx series canister, but I'm not sure how, seen it on forums before, perhaps google can help you?

You can use an external powerhead to drive water in directly. So you are using it like a prefilter.

Eheim 2213 have an output of 440 L/h.
Find a pump which have a similar or bigger output,get the one where you can control the
output.

Actually if is a external pump I really hope to get SOMETIng smaller as small as possible so tat is not unsightly. Any recommendations?

If you prefer to have the pump outside of the tank (less items in the tank), you can look at the external pumps from Eheim too:

Sorry just wondering for a 2ft fully planted tank pushing a canister 2213 size full of medias, which is the model that i shld go for?

Trying to get something sufficient not overkill so as to choose the smallest size possible.

Any pump that can run at between 600-1,000 l/ph would be suitable for 2ft planted tanks... higher flow is better for densely planted tanks as good circulation helps to bring Co2 and nutrients more effectively to the plants and reduce dead spots.

With higher flow rate, you can also have the option to adjust the flow lower if required (rather than start with low flow and cannot adjust higher).

[instinctloh]

Ok last 2 questions to achieve what you says, a 1000l/ph is it sufficient or is best to go for a slightly higher one?

Is it better to be submerged or outside the tank? As after reading the ehiem web it says can be used in or out of tank. Will it get heated up? Reason of choosing out of the tank cause I wanted it to look neater. Or is better to be inside? If is really better I will put it in.

Sorry as is my first time using such a pump. Thks

1,000 l/ph would be more than sufficient, at that flow rate you may even need to reduce the flow too... but if you plan to fit additional equipment like inline Co2 reactors and chillers to it (which will reduce the effective flow rate), then the higher flow rate will help to compensate for that.

If the pump is used submerged, you'll have one more additional equipment in view inside the tank so have to find ways to conceal it, and there would tend to be abit more heat transfering from the pump motor into the water. The benefit is there will be less noise as most of the pump motor's vibrations are kept inside the tank.

If the pump is used outside of the tank, you can place the pump anywhere to hide it and there will be less heat transfer into the water (most of the motor's heat will dissipate to the surrounding air instead). The noise from the motor may be more noticeable though (depending on the pump design).

I guess it just depends on your equipment layout and preferences, just have to try out both methods and see which work best for your setup.

Is 650 liters/hrs the size of an apple external pump at 6 watts good enough?

Should be okay, you'll just have to test it out and see if it works well for your setup.

Instinctloh, kindly refrain from using the sms lingo in your replies.

Yes yes I'm sorry. I keep forgetting. Is my fault. Will remind myself again.
