CeeTee Posted June 20, 2003 Share Posted June 20, 2003 All I added was calcium and Reef Vital and yet it went from 1026 to 1028 and stayed above 1026 even after top off. Link to comment
surfy Posted June 20, 2003 Share Posted June 20, 2003 You might have had an air bubble on the needle of the hydrometer if it is the cheaper dip in type. Link to comment
blk_g20 Posted June 20, 2003 Share Posted June 20, 2003 what are the general opinions on the Coralife Deep Six? i bought one and seem to work fine, but i have none other to compare it to. also, are the $50 ebay refractometers worth the investment? Link to comment
Deimos Posted June 20, 2003 Share Posted June 20, 2003 Refractometers are always worth the investment if you have the extra cash. That being said..I've never had an issue with my Deep Six..sure its off by as much as 2 points on occassion when compared to an "accurate" reading from a refractometer..but thats a give or take that I'm willing to live with when it comes to SG.
