was thinking of a RIO 20HF or a Resun MD55

any suggestions?

[blueheaven]

Go for MD55

[Alvin Tan]

yea....go for MD55..

[jem]

hmm..but looking at the running cost..

wont the md55 be much more expensive?..as its wattage is higher?..

is it also noisy?..cos my tank is in my bedroom..

[jem]

was also wondering..

is the Resun MD55 an china-copy of the Iwaki Md55-RLT?

they recomendded the iwaki..but i don have the budget to get the iwaki..

so maybe thought that the resun md55 has the same specs as the iwaki

would it be overrated if i run the resun md55 for my beckett

for a downdraft you will need a powerful pump. ETSS 800 rite?

oh well.., i'll type it out for you.

Downdraft skimmer use a big pump to inject water down a narrow tube at high velocity. This thin tube usually has bioballs or like media in it. These are not intended for biological filtration, although some bacteria will inevitably develop there and participate in biological filtration.

The real purpose of this media is to whisk water through the baffles (bio-balls) at a high speed to create ultra-fine bubbles like whitewater in rapids. The crashing water forced through the bio-balls creates very effective form, which is then channeled into a box below before continuing its way to rise and accumulate skimmate via a larger reaction chamber.

oh..so any pump to recommend?..

im more worried of the pump =)

thanks for the info more about the skimmer!

[jem]

decided to go for a md55 =)

oh ya...if i were to put it out-sump...

do i need to elevate it above the sump level?..

[weileong]

MD55 must be out-of-sump.

No need to elevate above sump level.

[jem]

yup =)

thanks weileong

so..tot i heard someone mentioned that skimemr must elevate above sump level if use externally of something like that...

elevation of skimmer only applies under what skimmer condition?

care to explain more please =)

[tineng]

i runned the smaller version of it before......20 inch heigh with a single tube....was working quite well using a Rio HF14.....

but yours is a taller version with dual tubes.....so maybe 2xHF20 then got enough.....

just have to becareful....with downdraft, too powerful a pump will create too much turbulance to properly skim out anything....also my experience is that the number of bioball in your tube affects the bubble count so if you are using a pump that is not recommended by the manufactural you might need to play around a bit....

[jem]

hmm..mine is the two tube is join together to combine it to a single tube if you get what i mean..

u think a md55 is overrated?..or issit "underrated"??

read that they recommended the iwaki md55...

how different is the iwaki from the resun?

[weileong]

Now I see you're referring to the skimmer.

Recommended for the sump water level or the elblow at outlet tube/gatevalve to be lower than 50% of the main body of the skimmer if not the skimmate might get too wet and also unstable skimming.

here's the link to a brief on Resun MD55

and here's for Iwaki

the price different is "one sky, one earth"

[jem]

thanks bros =)

anyway..this topic rather misleading..

i thought it was a beckett at first..sighs..

in the end..read up more bout it..found out it was a DOWNDRAFT skimmer...

bought on impulse..

just wondering..does it skim as good as a beckett?..

if not ill sell this off and get a beckett..muahahha!
