Then when we come to chillers, do we want to oversize a chiller? I suppose if the overall cost savings is evident when we use a bigger chiller, we should oversize compared to what the face-value ratings of the equipment suggest.
A chiller rated for 200 gallon tank is used on a 200gallon tank. Temperature is maintained at 27deg. Does the manufacturer gives the assurance how long must the chiller run in a day to sustain this 27deg? So end up this 200gallon rated chiller run almost 24 hours a day just to keep the temperature at 27deg. But the manufacturer not wrong and you cannot sue them, especially when they have rated the chiller able to maintain 27deg for 200gallons. But then comes the next chiller rated for 300gallon tank. End up although it uses more electricity than the 200g during its operation cycle, it maintains 27deg not by running the whole day. When the overall dollars and cents is calculated, it is actually better to use this oversized equipment which ran less often throughout the day, let alone the capacity to maintain this 27deg when ambient temperature soars during hot spells. So, oversizing, does have its tangible and obvious benefits as well. |

Thanks for the reminder, but I can't bring myself to vote because there is quite a disparity between local products depending on who makes them
So i cannot say i wholeheartedly support local products or i wholeheartedly shun them. Given a choice, I would vote, I will support local products selectively, very selectively |

This is the History liao for all my corridor of tanks which includes both freshwater and saltwater tanks as I am not a slave to them. You should be the Lord of the Tanks (like yours truly) by having more time admiring your setup after a hard day's work instead of doing periodic partial water changes. Fyi, my matured 6ft marine tank (outside the house where it is bombarded with our weather conditions) has not been gone thru any partial water changes except topping-up water due to evaporation loss. If you manage the water well .. the fishes will take care of themselves! |

I don't know which ferrari model you are referring to. Anyway we take the Ferrari Enzo as an example. Power: (SAE net) 650 bhp @ 7800 rpm Torque: (SAE net) 485 lb-ft @ 5500 rpm Redline: 8000 rpm Transmission: 6-speed manual with automatic shifting and clutch Final-drive ratio: 4.10:1 Gear Ratio Mph/1000 rpm Max. speed in gears 1 3.15 6.3 50 mph (8000 rpm) 2 2.18 9.1 73 mph (8000 rpm) 3 1.57 12.6 101 mph (8000 rpm) 4 1.19 16.7 134 mph (8000 rpm) 5 0.94 21.2 169 mph (8000 rpm) 6 0.76 26.1 209 mph (8000 rpm) 80km/h is about 50 mph so we drive in 3rd gear at 4000rpm or 4th gear at about 3000rpm. I didn't know that driving at mid of the torque curve will spoilt the car man... Like that cham already I go to work already traffic jam and looks like my 3yr old car need to be scrapped soon, heng heng COE dropping :P You ask an olympic sprinter to walk slowly he will not have any medical risks but if you ask an ah pek to run like an olympic sprinter...sure up lorry one...lol |

All skimmer removes trace elements along with DOCs and some toxics released by life forms in your reef. When you feed, you will also introduce some heavy metals into your tank, all these will slowly accumulate. Water changes will take care of all these. Frankly speaking I still have no confident to do that. With sensitive fishes like AT swimming in my tank, I feel I need to give them the best of everything. If I skip in my water changes, my AT will come knock my head and complain to me. For the sake of my AT I still spend 5-10mins every weekend to do the 5-10% water change :P With proper planning and setup water changes can be made very easily. |

hi there, interesting
Quote:
water changing is your personal regiment. but the question here is about the need to oversize a skimmer and the removal of trace elements due to over-skimming. which u have not answered yet. Whether u keep AT or damsels, it does not matter at all. It does not even matter if u manage to keep a shark. i do appreciate the response tho, cheers. |

driving a ferari at 80km/h is under utilising a quality machine. if u really understand the dynamics of the ferrari engine, u will know that u cannot do that for a long time. the engine will be ruined. With regard to chillers, manufacturers have tested their pdts and made recommendations to the fish keeper accordingly. that is for what gallons,, use which model. Like i said previously in my reply to bro roidan, at most u factor in the halides. your example of the ah pek and sprinter is totally amusing. my question was why the need to oversize... I did not say u shud undersize your chiller. no offence, but what u just said is kinda no meaning....and i dun understand a single bit. |
