  1. Ch 8 reports that NKF says you can call them to request to return the donation you made during the NKF show.
  2. Congrats.... just one step away
  3. There will be more signatures this evening when pple logon to the net after work.
  4. When the PO4 reading is very low (lower than around 0.1ppm with the hanna colorimeter) with your salifert test kit, my eyes already difficult to see the color. With the hanna is shows you a reading instead of telling you compare the with the test chart, most pple just assume colorless at that time.
  5. Sorry reliable PO4 test monitor using ISE are way to $$$ for us, you can try the colorimeter. Avaliable from Hanna Singapore, check yellow pages for details. Price ard $350, reagent abt $40+/100 test Remember get the LR one.
  6. The news report that the NKF board of directors fully support Mr Durai.... oh well Don't think he's going to step down.
  7. Want to buffer tank better then use a better skimmer
  8. my guess: pic 4 - montipora digitata. BTW how come all the photos seems upside down?
  9. I sending a platoon to ambush you liao
  10. and when they start to rust, you'll be migrating again
  11. The longer downtube actually reduces the head lost hence you get better skimmer performance.
  12. Deltec says if you use in FR you should wash it, or rather run it thru with fresh water until the water coming out of the FR turns clear. If used in filter bag then no need to wash.
  13. Then you need to buy the colorimeter for other ions. There is one that works with multi-parameters but of course much more expansive.
  14. The idea of FR is to prevent channelling from forming hence reducing the reducing the efficiency of the media. You can use FR but provided the flow thru the FR is slow, that's the point you're missing. That is why if you put the GAC in a mesh bag, you're supposed to knead it daily to prevent channelling.
  15. Actually few ways of doing it. 1. Put GAC in FR but with reduced amount and slower flow rate thru the FR, smaller FR in this case compared to rowaphos. 2. Put GAC is mesh bag in low flow area, mesh daily to prevent channels from forming and to clear any detritus trap in it. 3. Put in high flow area but with very small amount, changed regular basis will work too.
  16. Choose one that gives the following: 1. Ease of maintenance, removal of collection cup,injector etc etc 2. Less turbulence 3. Give less micro bubbles at outlet. And most important of all, one that does leak!
