The taper is actually a very important part in translating the bubbles very smoothly from the bigger chamber to the smaller tube up the cup...otherwise...some bubbles will be LOST IN TRANSLATION
-
essentially the same thing isn't it... main chamber tapers via a gradual taper to a smaller tube to go into the cup?
-
anyway, i tot the bubblekings also taper at the collection cup? main body tapers to a smaller diameter tube to go into the cup...
-
for those who wanna know the price range...please refer to past sales of the same model...... http://www.sgreefclub.com/forum/index.php?...=21705&hl=ev240 for mebner resale price range u can refer here http://www.sgreefclub.com/forum/index.php?...13853&hl=mebner

But make no mistake..i got nothing against bubblekings...i am very much in awe with the efficient performance...take nothing away from the germans...in fact i am very infatuated with germany technology and engineering precision. if there is a 2m tall bubbleking that maybe cost 4k-5k, even though twice the price of my QUADbeckett ..i will gladly pay for it...anytime baby....anytime we can safely say that both beckett and needlewheel methods have their followers and both methods are in a way at their peak of delivering perfomance in a reef tank...from satisfied testimonials as such...if the long term price difference is not too much even considering cost plus running, it will be indeed a headache to discern and choose between the 2 types.. but if the price difference is as much as one costing only 20% of another, then i am afraid that even if the grossly expensive method has an advantage in performance...it is definitely not going to justify the large gap in price

haha...okok... hereby submit my thesis on why i chose the beckett way why i chose to go the beckett way over a needlewheel such as bubbleking.... firstly, i asked myself, how much would a deltec/H&S/bubbleking cost if it was built to over 2m high and 10inches wide.... and to logically go by proportion, if my 66.5cm high and 15cm wide H&S uses 38W of needlewheel action (excluding the feed pump)...by volume of water in the skimmer structure, i would need a high wattage needlewheel pump or pumps to sustain bubble density in a skimmer 2m high even if i choose the needlewheel way. The bubbleking 650 extern stands at 85cm...abeit a wide 12inch chamber...but the absolute volume in this skimmer is much much less than a skimmer built to over 2 metres and 10inch wide...and it consumes 2x58W of red dragon pumps.... Volume of my skimmer= pi x r x r x h = 101341 cubic centimetres Volume of the 650 extern BK = same formula = 62021 cubic centimetres in other words...my skimmer is 63.3% bigger than the 650extern BK But how much does the 650extern BK cost in their website? a cool EURO4927....which means SGD$10,194.26 my skimmer cost will probably be just about 20% of the 650extern at SGD$2k odd So now you look at the size and price....definitely one would accept a skimmer that is 63% larger and yet cost only 20% of the other with a price difference of $7000-$8000....even if i run 2 super hungry iwaki pumps...it's probably gonna take more than 10 years before the 650extern becomes a cheaper option....just like what i did for comparison between iwaki and RD pumps...it's the same theory....u can plot a graph yourself with different starting costs and incorporate different running costs and you will know where is the cut off year before they meet each other....i am lazy to plot this graph....but if for a smaller cost difference between an iwaki and RD have led me to realise it takes 2-3 years before the RD is a cheaper buy+running option.....the 7000-8000 difference will definitely take more than 10 years to make up for. And worse...if the bubbleking is built to the volume of my skimmer, it will probaby cost around SGD$16,657 by proportion. wow...that means the difference becomes SGD$14,000 compared to my skimmer. $14,000 of cost difference, it's going to take hell lot of years to make up for even with rising PUB tariffs. Now the next question is, even if they are the same size, probably the BBking can squeeze more air and water into the structure using the highpowered, efficient but terribly expensive RDs... which is why non BBking designs like mine have to use the cheaper iwakis....2 mx100s to produce as much bubble density as the energy saving RDs. not convincing? let me throw in 4 mx100s to the equation or 2 mx250s instead to produce as much, if not more, bubble density if reefers are totally hyped up about bubble density. Bottom line is that it is still going to take YEARS or DECADES to make up for the SGD$14,000 difference in cost between the 2 same size 2over m high skimmers just like alanseah said in a way....to each his own....a very efficient honda s2000 engine can produce about 100bhp/litre of engine capacity without turbocharging or supercharging....that is very efficient. A dodge viper engine is 8.3litres but only produce 500bhp...i.e. 60bhp/litre the efficient s2000 engine is likened to the BK.... efficient....100bhp/litre....just like high flow/watt the dodge viper is totally brute like becketts....big...inefficient.....60bhp/litre....just like lower flow/watt comparitively IF the 2 are equally priced, of coz EVERYONE will go for the efficient BBking skimmers...but the sad fact is that if a dodge viper only costs 20% of the honda s2000.....i am sure many would get the SUPER THIRSTY dodge viper...why? because when the car is scrapped at the end of 10 years....the dodge viper which only costs 20% of the honda s2000 is still a cheaper cost PLUS running option... but fortunately, the honda s2000 is much cheaper than the dodge....which makes total sense to buy it....spend less...get a much efficient option.. and when you plot the cost PLUS running for the dodge and honda.....the honda will ALWAYS be cheaper and they will never meet while the dodge graph shoots towards the skies. Why? because BOTH COST and RUNNING are low for the honda. But in this case of the skimmers, sadly the BBkings start off with astronomical COST and they have to wait a while...in some cases longer than others, before proving that they are the CHEAPER LONG TERM OPTION

no problem...for me...i am gradually getting rid of all the miscellanous pumps already.. running a full iwaki lineup for my system soon

i already know someone will make such a comment some friends and i were betting on it.....and who will be the one aiya...of coz just for a moment lah..u think long term confinement meh my doggie very cooperative... just carry him up....slot him in via his 2 hind legs....and just nice his 2 front legs perch on the top.....heng he is slim...unlike me.... oh yeah..i was also thinking of asking a cousin to pose inside the middle section of the skimmer....dun tell me i will get reported to human rights activists groups

u may ask...is the dog super small or the collection cup is super big.... that.....i dunno how to answer you
-
thanks alfa...never really measured it...maybe those who have seen it can help me determine the length.... that was niceeeee: sailfin also quite big...can compare to AT maybe patrick123: so far haven't fail on me yet...still using it on my ev240 UPDATE: skimmer is soon to be comissioned...here is the collector cup with my dog in it.....yeah..this is just the collection cup somehow reminds me of the walking pram that babies learn to walk in

here's the one i traded for very pastel pink...and guess wat...a free tiny sibling by the side to the bro....thanks a million for the swap.....i know you dun want to be harassed by naming you out..i respect your privacy..but i can't resist sharing this pic with bros here
