BumbleBeeJBG Posted November 29, 2009 Share Posted November 29, 2009 Mag 1240, Calcium 450, Alk 6.5 dkh, no matter how much component 1 of the Alk/Calc ESV buffer system I add, the Alk never rises, stays steady at 6.5. Any ideas? Link to comment
Mr. Fosi Posted November 29, 2009 Share Posted November 29, 2009 What does your pH do? Have you tried mixing up your own? Link to comment
lakshwadeep Posted November 29, 2009 Share Posted November 29, 2009 What are you using to test the water? Link to comment
BumbleBeeJBG Posted November 30, 2009 Author Share Posted November 30, 2009 I may have just been not dosing enough. I was putting 5ml a day into the tank with no effect, doubled it to 10 yesterday and now I'm at 7dkh instead of 6.5. I don't have many calcium demanding corals but I have a ton of corraline. Perhaps it's serving as a huge drain on my alk levels and I just have to dose a lot? Link to comment
Mr. Fosi Posted November 30, 2009 Share Posted November 30, 2009 Good working hypothesis. Link to comment
nanoreefer4life Posted December 1, 2009 Share Posted December 1, 2009 Coraline algae need alk to build itself Link to comment
BumbleBeeJBG Posted December 1, 2009 Author Share Posted December 1, 2009 Coraline algae need alk to build itself You know I've always known this to be true but I guess it never clicked that this could be a measurable drain. Link to comment
rahorman Posted December 2, 2009 Share Posted December 2, 2009 i have a ton of coralline in my tank (that I really need to scrape out) but my alk. is always 6.5 / 7 . Would an abundance of coralline lower alk? Link to comment

BumbleBeeJBG Posted December 13, 2009 Author Share Posted December 13, 2009 Long story short: Elos Test (1) (tank water) - 6.5 dKH Elos Test (2) (tank water) - 6.5 dKH Elos Test (Salifert 7.2 dKH (-/+ .3) test solution) - 4.5 dKH Salifert Test (1) (tank water) - 8.5 dKH Salifert Test (2) (tank water) - 8.5 dKH Salifert Test (Salifert 7.2 dKH (-/+ .3) test solution) - 7.4 dKH Should I have any confidence at all in my entire line of Elos test kits? Posted it on the sponsor forums Elos has on the evil site: http://www.reefcentral.com/forums/showthre...77#post16197777 We'll see what they have to say... My corals started to look like poop when I dosed according to the Elos kit Link to comment
Mr. Fosi Posted December 13, 2009 Share Posted December 13, 2009 Stick with the Salifert, IMO. Link to comment
BumbleBeeJBG Posted December 13, 2009 Author Share Posted December 13, 2009 Stick with the Salifert, IMO. ugh.. should I get new kits across the board? Link to comment
Mr. Fosi Posted December 13, 2009 Share Posted December 13, 2009 Dunno the answer to that. What I do know is that the Salifert alk kit reads within 10% of what standard methods total alk does. Link to comment
lakshwadeep Posted December 16, 2009 Share Posted December 16, 2009 +1 to erring with the Salifert, which has an older reputation for quality than elos. You probably picked the wrong subforum at reefcentral to ask your question about the elos kit's quality. It appears that both test kits are precise (consistent), but the salifert kit is more accurate (closer to the true value). Link to comment
Mr. Fosi Posted December 16, 2009 Share Posted December 16, 2009 In response to the RC thread: I guess I don't really care what organisation tests what kits. If the kit is bad, it's bad. Link to comment
BumbleBeeJBG Posted December 16, 2009 Author Share Posted December 16, 2009 Can't a guy get accurate test readings and be confident?! ARGH! Link to comment
BumbleBeeJBG Posted December 16, 2009 Author Share Posted December 16, 2009 I came clean on the other thread Fosi and we'll see how the drama unfolds after that post. Still very interested in the results though obviously Link to comment
