    swop rics

    borinz, are u the same person mentioned by shoelevy in the thread below? http://www.sgreefclub.com/forum/index.php?...pic=31646&st=15 if not, that means u are another one i wonder how many others out there did the exchange or backed out of the exchange after seeing his rics, hope not all his rics for exchange are like dat
  2. we do not know if there has been truly a misunderstanding or a real intention to cheat..... so just share with us the incident and let us avoid such similar situations with fellow other reefers..... let's not judge whether is this guy or that guy is a cheat or not....but rather, let's just wise up to the situations that can lead to misunderstanding or the situations that are open to exploitation. That will be for the greater good
  3. shoelevy, while we do not know if there are any misunderstanding or intention to cheat, it would nonetheless do us good if u can tell us to your best knowledge, how the situation happened and why your friend had such a sour experience. so that we can avoid similar, truly unintentional,future misunderstandings with fellow reefers or future exposure to such situations where cheats can exploit.
  4. how was this friend cheated of ricordea?
  5. hehe tim... anyway, did not see the griffis in iwarna today...probably bought by someone already....probably from the Hullet house?
  6. those people 身在福中不知福 mah....we are getting reasonably good prices as vili said already, but u see those aunties at wet market u know liao...even 10cent savings also shiok one u know?
  7. http://www.themarinecenter.com/griffis1.htm the earlier one reported to heaven because it's an angel after all hope this one don't report too early...hehe ya..nothing red on this fish..if only got some green.... green, black, white i sure grab one

  9. ya....hehe another gadget for DIY gurus here to make

  12. aiyo boss... i think i saw this off somewhere..... slashes from gangfight lah

  14. I am running mx100s...seen mx70s at a couple of reefers homes the fan has a whirring sound that may be audible for you since u say that noise is a significant issue.. i suggest that you get non pressure rated pumps and minimise your pipework to get the most out of those pumps
  15. seems to be pretty near land mass.... hope wun have tsunamis again
  16. while we do not know the terms between them or whether there has been a misunderstanding or miscommunication...... I would definitely want to know who bought $1.50/kg coralline encrusted live rocks...... he has probably gotten the deal of the reefing century any cheaper and he has to harvest from local waters himself
  17. no surprise at all... korallin design is for pressurized chamber and thus the co2 usage rate is very low....i also bubble around 1 bubble per 8-10 seconds.... i used to bubble much faster and end up the whole chamber gets chalky/milky faster due to excess dissolution of the ARM...hehe
  18. ya..normally these kind of so called town council maintenance thingy seldom pass 1hr one.... but like what your neighbour experienced, apparently many does not even allocate excess capacity for backflow in event for power failure....or prevent it via one way valves or siphon holes.
  19. System & Control Engineering (beside boon keng mrt) Block 22 Boon Keng Road #01-23 Tel: 2964916 They sell daeil chillers....but they service other chillers like teco as well.....
  20. the beauty of UPS is that it takes over, providing power automatically when the normal household power fails for one reason to another.... if u want to take it much further.....is to use a pure sine wave inverter that converts, say a 12V car battery, to provide power for appliances..... means say if u clip a 100AH 12V car battery to this inverter, and you draw 50W (agar 0.2A)....ignoring complex calculations, you may be able to extract 500hrs of operation from the fully charged battery alone.... that's 20days of operation just on batteries alone but you must be home (taking over part of the UPS job) to unplug those equipment off the house circuit and plug them into this inverter to enjoy continued operation... and if the battery runs out of juice before 20 days, u can always go to your car to use yet another car battery
  21. if u see how a stream works in your tank, you will notice that the broad cone of water movement generated does indeed translate alot of water over corals and stuff..... whereas you will need quite a number of air stones/pumps to create a similar kind of turbulence in the water column if the tank is large whereby only areas immediate to the airstones have movement whereas areas further away remain very much still and undisturbed by what the air bubbles can do. in fact just by my ts7 only (7000l/hr max) i see movement induced by it at the other end of the tank easily. definitely more than movement from airstone bubbles placed at where the stream is....or putting the airstone in the middle of tank....(yes, i have used DC/AC airpump before also and i can see the obvious difference when it comes to surface/water column turbulence ) if you are talking about a 2-3ft tank, maybe the turbulence from airstone bubbles is enough to create movement in the water column as well as water surface...but when u come to tanks of 4-6ft.....even if u place the airstone directly in the middle of the tank...u will notice that surface and water column turbulence towards both ends of the tank will be very weak. but all in all, i would still advocate using DC/AC airpumps for emergency, than nothing at all
  22. the sockets for me to plug and play..hehe.. i do these and other failsafes to make sure that I am not the weakest link when it comes to disasters happening to the fish tank... If i can cover most points of possible failures/weaknesses, i still can accept it if things that are out of my control happens.... at least i can tell myself that i did not crash my system or subject it to stress by saving some money when i have spent much more on my system.
