Refractometer and LED

[bangbangkhan]

I wanna buy a LED and a Refractometer....I was looking on ebay but couldn't make my mind up. There are so many options....specially for the Refractometer...I am willing to buy one around 20-40 and maybe 300 on LED

Your assistance is always appreciated! Especially weblinks ;) since I am so lazy

P. S for a 30 gallon tank


Cheers

Sorry to say, but I really don't think it matters (about the refractometer)! Close your eyes and point! Don't forget to get the calibration fluid too. :)

But they are so cheap....practically the price of a hydrometer?

Yes... But common, the pet stores need to pay sallaries and taxes..so obviously for refractrometer they raise the price by 10 $ and that is normal...

About leds... In ebay,be sure not to buy them from china... be sure,that they are shipped from Germany, USA etc...
