Justin_Luke Posted January 20, 2015 Share Posted January 20, 2015 Over the past couple of days I noticed that my staghorn coral wasn't showing any polyp extension. I have had this frag for about 3 weeks and this is the first sign of anything wrong. It has good flow on it. I have two other sps corals in my tank that are doing great (purple rimmed monti cap and blue rimmed Monti cap) but for some reason the staghorn just doesn't look good. The rest of my coral is doing great as well. Here is the breakdown of the system: 5.1 gallon tank weekly 1 gallon water changes with kent salt params: nitrate - 2 calcium - 450 ppm magnesium - 1350 ppm KH - 6dKH - 2.16 meq/L ( a little low) the only other thing that might help is that i have also noticed diatoms forming on the sand which i usually don't have a problem with. Is it the low dKH that is causing my problems. Any advice would be greatly appreciated!

basser1 Posted January 20, 2015 Share Posted January 20, 2015 Alk is very low, I keep min at 9 dkh. Also have you tested for phosphates? I'll bet they're high. Link to comment
ew_fish Posted January 20, 2015 Share Posted January 20, 2015 Thats not a staghorn that is an Montipora Digitata Your alk is low I would try and be at 8dkh if your not running an ULNS. Link to comment
Justin_Luke Posted January 20, 2015 Author Share Posted January 20, 2015 Sure thats not a staghorn? Also can doing a water change bring my dkh levels back up? Link to comment

Just like anything else you learn as you go. You can do water changes to raise your alk but if the salt mix dosn't contain high alk then most likely wont do much. I suggest 2 part dosing if your going to start collecting more sps. Those caps grow fast and will start to suck up alot of alk and cal. Two part is cheap even cheaper because your tank is only 5g. Remember with sps you want to keep things stable (alk,cal,mag,temp) Those are the main ones there are a few others but don't effect as much (more advanced) Good luck hope this helps Link to comment
