Skimmer

[oceanics]

Hi a Skimmer is a Skimmer, operate by wooden air stone or Power Head, why some can get "Kopi O" some can get "Urine" some get green tea.

[Sinn]

it depends on a few factors..

based on what i could remember, the important ones are

bubble size - the smaller the better as there is more surface area between the bubble and the water to attract proteins and other harmful stuff

contact time - how long the bubbles remain in the chamber, thats y counter-current skimmers are better the co-current skimmer, even though they share the same height. some skimmers are designed such that the bubbles would swirl ard the chamber, increasing contact time.

how high the foam must rise - the higher the foam must rise, the 'dryer' the bubbles, the more black it gets, but not to the extent that the bubbles only break at the 'neck' and collects gunk there.

That's a model answer Sinn....

Pardon me for asking a newbie question.

But does that mean venturi skimmers generally work better then those using wooden airstones in a 3 or 4ft tank?

Since contact time is an important issue, how will a DIY using wooden airstone that is 2-3ft in height compare with a venturi skimmer that is lower in height?

for me, i would certaintly prefer spending more for a venturi... im having a 3ft... used to be running on an air stone one.. collecting errr 'urine' as oceanics said... i've since upgraded to a weipro 2014 that is collecting dark green tea.. almost brown actually.. so i think it's safe to say that venturi driven skimmers work much better then air driven ones...

I'm using the Orca brand ($20) which uses airstone for my 2ft setup. Quite impressed by it. I replaced the ceramic airstone with the wooden one and adjusted the water level to get better results.

I wud recommend this for small tanks and tight budget.

I have been reading quite good comments abt weipro skimmers. Any other brands of good skimmers around that price line?

[metals99]

But it also see if your tank are dirty like mine would be filled with yellow stain if its real dirty and it also depends on how fast your bubble flow is clean bubbles should burst before going up to the collection cup..

and also depends on your air stone quality also..

use a good one.. i am using sanders air stone..

if the tank not dirty its difficult for air driven skimmer to skim..

thats a disadvantage of it..

weipro skimmers.............

if we dun haf a sump... then how do we place it??? Its not hang on rite???

didnt see one b4... thinking of getting 1..

my air-stone kind...sux...

weipro can be hang-on the tank or place in/out of the sump. i just got myself 2013 + weipro pump (2500l/hr) this afternoon. quite impress by its performance. i got a Remora Pro for my 3 ft and this 2013 is for my 2ft. although weipro cannot compare with Remora, but its really value for $$. 2013 selling at $78 and the pump is only $38

got no skimmer at the moment ... dun really want it as it will increase the temp ... but seems tt i got no CHOICE.

[kuxion]

i just bought a weipro 2012.. what should be the good bubbling level.. i m trying to control the valve to set it up to the collection cup.. is that too high.. it overflows once just now.. pls advise wat is the best level?

Read here for everthing you need to know about protein skimming.

Very informative... but the last part i feel that the writer is just advertising his brand of skimmer as better then all the rest.

Anyone share my views?
