  1. hehe.... matters regarding $$ i shall not comment so much
  2. like i said bro blenny... aquaC use high flow maximum tank turnover rate method of skimming...HnS use low flow maximum contact time method "The overall flow-thru rate and quality of contact time are not as clear cut as the previous two measures. Some have reported that high flow-thru rates (several hundred gallons per hour) yield the best results. Others argue that a slow, leisurely flow-thru rate facilitates the best skimming. Most likely, both schools of thought are correct in their own way. The actual chemistry behind the mechanism of protein skimming tells us that, in order to remove the maximum amount of waste possible per bubble, we want a very, very slow flow-thru rate. This makes perfect senseā€¦ If the flow-thru rate is slow, each individual air bubble can react with the water for a longer period of time. Air bubbles, after all, don't become saturated with proteins immediately. Research suggests, in fact, that they continue to become coated with organic compounds for up to 12 minutes (Harker). The problem, and this is why the "high flow-thru rate" school of thought is also partially correct, is that aquariums are closed systems which need to be "cleaned" at an efficient rate of speed. Imagine holding a vacuum cleaner over the same section of carpet for ten straight years. Sure, that little square of shag might be extremely clean once you are done, but what about the rest of the house?? Our goal is not to maximize the amount of protein removed per bubble, but to maximize the amount of protein removed per unit time. An efficient protein skimmer, then, is one which removes the largest amount of waste in the shortest time possible. High flow thru-rates are beneficial because they allow large amounts of the aquarium water to be processed rapidly. Although less protein is removed per bubble (because the air and water are not being allowed to react for very long), it is possible to treat the entire tank volume in a short amount of time. There is probably a middle ground which yields the best results. It is important to note that both high and low flow-thru rates can and have been used effectively, and neither method is definitely better than the other. Our own research with different flow rates and air-injection methods suggest that for larger tanks (100+ gallons), higher flow-thru rates are better suited than slower ones. This might be due to the added benefit which high flow-thru rates provide; more thoroughly oxygenated water. The real answer is far from clear, however. "
  3. no lah..must be my clumsiness banging into things wherever i go.... very loon joon one...
  4. u try the insump one lor....shorter.... this one is the outsump one
  5. bro trevally: happy with it? hehe what pump u intend to use for it? THANKS again
  6. i think taller than ev240....din compare...must go online to check the height....but lose to ev400 i think... this H&S use low flow, tall chamber and fine bubbles...sure maximise organic coating on the bubbles...but tank turnover rate will be slower than aquaC i guess
  7. hehe... anyway, the skimmer is quite tall.... can see already way past my knee cap....
  8. yeah.....imagine the aquaC being churned by my 4750litre/hour pump...non pressure rated of coz... and this one recommended for 1000l/hr pump by SL, really can see the difference in approach to skimming ....like the paragraph i posted earlier...different schools of thought.... bro deepblue...yeah....no wonder you posted that you liked it after collecting for your friend... the bulk order really worth it
  9. my new H&S 150-F2001 Many thanks to bro trevally for banding the 3 of us...thanks thanks
  10. hehehe... coz my tank looks better in pictures than in real life mah.... ok...going off soon..hehe...then later meet 2 bros at SL
  11. steady...lol... lend me best...but er...lazy to clean the algae for showroom condition leh...LOL you are at ubi right? i later around 5plus going to joo seng road area...i take from you? hahaha... i offer you my IC as collateral in case you scared i run away with it...lol kidding lah...office equipment cannot anyhow lend i understand..hehe cheers bro..hehee
  12. yeah ..dennerle is good.... i saw azoo ones about $300 in the net...but dunno good or not..lol..dun have confidence lor.. hmmm..i always see dennerle vans park halfway up T95...why ah... wah...use your office one ah...good good..but how old is the probe or the whole set? maybe u go get another probe from your office to check your tank again..maybe can see difference this time.. hehe..ok... u are a good honda customer...hehehe ok lah..let's not digress further from fishy topics..hehe one of the few cardinal rules
  13. yeah...they are inversely related if i am not wrong...ph goes up..orp tends to go down....and vice versa...thats why if can maintan the ph at the same level..makes observation easier... but orp is not an essential or conclusive thing to gauge tank condition lah...if your corals and fishes are doing fine...then keep up the good work without it... i am just a bo liao person seems like bro weileong has joined me for company...hehehe bro weileong ah...any idea where to get good PH controllers? i ask around for burkett ph controller system...wah liew...thousands...i think really for industrial use...i shall not pursue further on this kinda industrial brands....lol hmm...not frenly ah....you always bring your car ask them to fiddle this fiddle that issit? hehe u have the luxury of being so near...any little problem can go and see them everyday if u want....others maybe dun mind living with some small problems or at most wait till problems gather or compound before making a trip down..hehe
  14. yeah... but mv fluctuates with ph level changes also....so if you want to monitor your orp..make sure you make comparisons at the same ph level.... wah..u surfing from honda's showroom/service section ah....shiok.... at least better than reading magazines, newspapers or keep looking at tv screens looping the same car financial advertisements..hehe
  15. not chio lah....more chio ones around...secretly admiring their own tanks and laughing at my amateurish setup.... My kh i maintain around 9dkh....dose buffer mah...the drop can be due to many reasons....normal carbonate consumption of your tank system....or precipitation coz when you intro the buffer solution..more precipitate out rather than completely increase your system dkh...or calcium too high....so whenever you push you dkh up...the calcium went to push it down....or magnesium level not very optimal for sustaining your cal/alk balance...or other reasons.. i may or may not be wrong with the reasons above...dun take my word for it.... after seeing your post i went to test the tapwater by putting the probe in a pail of tapwater.....reading immediately fell from 331mv to 180plus...within 5 seconds or so...but i din wait for the reading to stabilise though so i guess, my probe is still working...at least it can differentiate my tank water and tap water in a fast response time
  16. just like some net info says about chevron, they really love hugging the rockwork and seldom make open water swim....
  17. seeing the chevron doing ok in the clam...i put him in last night to avoid immediate bully contact...hehe seems like all never bully him....maybe they seldom see such tangs around in places where they themselves live in..maybe thought he was a flame angel...hehe even yellow tang...din bully him...
  18. budget not capped yet because not blissfully married like you mah bro i guess as much i will run into many objection probems when married....so i better fufill this hobby before i get married managed to take more bartlett pics today...he swim damn damn fast....
  19. yeah man....a matter of getting what you paid for..abit expensive never mind..hehe
  20. thanks for the confirmation.... grandmaster AT has given the go ahead to use vinegar
