SRC Member oceanviper Posted October 12, 2009 SRC Member Share Posted October 12, 2009 Hi guys.... Just wondering whether Iwarna provide sea water for late evening buyer? So far I only noticed that the sea water sale is in the morning... Anyone went down to buy in the evening? Because I don't see any of it in the late evening.... Appreciate if anyone of you have purchased sea water in the evening (weekdays). Please kindly advice. Thanks.

kanegan Posted December 7, 2009 Share Posted December 7, 2009 Hi all, Has anyone measured the specific gravity for Iwarna's sea water? I bought one bag on Sunday and measured it at home with a Corallife deepsix and a floating type hydrometer. I got readings of 1.0185 and 1.020 respectively. I know that these two types of hydrometers are not very accurate, can anyone let me know the correct SG reading? Quote Link to comment Share on other sites More sharing options...
Solo77 Posted December 7, 2009 Share Posted December 7, 2009 bro, i doubt farm can achieve precise mix especially with evaporation, etc. U can take the average or buy a refractometer for more accurate reading.

And God blessed them, saying, Be fruitful, and multiply, and fill the waters in the seas, and let fowl multiply in the earth.

Happy reefing. I am puzzled because the SG seems so low... with evaporation the SG should be higher and not lower. float type is always out of accurarcy. hydrometer is more accurate. more for the swing arm type will give a 0.002-0.004 off from true value from my experience. I read elsewhere that the swing arm hydrometer is precise but not accurate. Precise in the sense that the reading can be wrong or right in terms of accuracy but it will always give consistent results (wrong will be always wrong by the same degree....) I just want to know whether the sea water I bought was really too low in SG or my hydrometers are erring on the low side. I have been keeping my tank water SG at 1.023 using the swing arm hydrometer... now i am worried that my own levels are actually too high. Can anyone who has been using Iwarna sea water share their experience? Do you add salt to the sea water? Quote Link to comment Share on other sites More sharing options...

Fuzzy Posted December 29, 2009 Share Posted December 29, 2009 I bought a Deepsix also when I started and used it twice, before I just tossed it aside and bought a refractometer. Got it on ebay from a company that only sells Refractometers (of all sorts, make sure you get one for salinity) on ebay, If I recall correctly it was around SGD$65 - $80 after all shipping charges etc. Aside from the questionable calibration, and the problem with bubbles on the swing arm, results even from the same batch of water were inconsistent, I had to take 3 readings and average them out.

macrobutt Posted January 4, 2010 Share Posted January 4, 2010 on the way to Irwana, turn into the 2nd gate on the right! Thanks for the reply. So its the same address as Iwarna? Quote Regards, Macrobutt Link to comment Share on other sites More sharing options...
Eniram Posted January 4, 2010 Share Posted January 4, 2010 No not the same address but its along the road leading to Irwana its the 2nd gate on the right. The moment you hit the road after coming down from the slope turn right (towards Irwana) drive down about 100m you will pass the 1st gate/entrance then 20m more you will see the 2nd gate. Thats where Ah Beng is! Once you are in the area look for the middle shop! You can't miss it and Ah Beng is a crew cut dude who always wears singlets. Can't miss him or his workers!

Kian Wee Posted February 18, 2010 Share Posted February 18, 2010 The sea water i use from iwarna is usually at 1.020. I don't add salt to it. Hi anyone tested the nitrate and other parameters of the NSW? I got mine from Iwarna last time... like they mentioned, always read 1.018-1.021. All else at 0ppm but nitrate sometimes at 0-5ppm... Recently bought some from Jireh Marine... did not test it till 5 days later... my nitrate in pico tank spike to 20-30ppm... intend to do water change and tested the old NSW from Jireh... nitrate is 20-30ppm just like my tank!!! I was told NSW needs to be used on the same day... anyone tested Jireh's NSW when its fresh? Will the same nitrate spike occur 4-5 days in my tank even tho it was low when fresh? Any good source for mixed saltwater? Quote Link to comment Share on other sites More sharing options...
