Salinity

[mark peacock]

Is my salinity going to do any damage to my corals i have just checked it and it is 1.027/1.028 i think 37 ppt i have not checked for a week but have notice that my elk coral has started to die off my other perams are ok.

Where do you normally keep it at Mark? It's more about consistency that you should be concerned about and not having fast drastic changes in salinity.

No, it wont damage your corals at that level. especially if it just creeped up and wasnt drastically changed from 33ppt to 37 ppt.

There are areas where the salinity is naturally 37ppt. The red sea for instance. Tide pools often climb that high throughout the day. Im not recommending to keep it at 37ppt.. Lower it slowly to 35ppt

I normally keep it around 1.025 about 34ppt i am taking it down slowly now just woundered thanks for your replys

Hi just an up date on my salinity i have just bought a new refractometer and i could not beleave how high it was my reading was 40 ppt so last week when i measured it on my resun meter it was showing 34ppt so last week my salinity must of been 43 to 45 ppt wow so checked my new meter at my lfs and the new one is perfect so plastic one is in the bin.
So same question as last week could my salinity of 43 ppt be very bad to my coral say pulse xenia and frags elk horn etc because had die off on the elkhorn and the xenia which was growing like hell was slowly disappearing.

Hi Mark, If you want to know for sure your dead on you should calibrate your refract to "53.0 mS STANDARDIZED FLUID FOR CALIBRATING YOUR REFRACTOMETER TO 35 ppt OR 1.0264 SALINITY" the stuff is cheap.

Hi scooterman the one that was given me the wrong reading is the plastic one you have to fill up which has gone in the bin my new is the one you have sent an web address for so hopefully get the salinity down and get the right reading going forward cheers anyways.

That is good news, your set, BTW I use the cheapy floater to get the make-up water close then I refract. to get it right

Hi thinking about it now i should of spent the money on this years ago going to get it to 34ppt 1.025 i think should be ok at this but doing it slowly so not to shock them to much.

Mark you are a loooooooog way away :lol: So, who's refract do you have ? Go to a local drug store, you must have them there. Have the chemist make you a 3.65 % saline solution using table salt. That means you take 963.5 grams of RO/DI or distilled water and add 36.5 grams of table salt to it. Make sure it is all well dissolved. Put a drop of this on the refract and re-calibrate the refract until it reads 1.0264 or 35 ppt or 3.5 % with the water temp @ 25 C. If you can find the PinPoint 53 mS solution there that is even better. You CAN NOT use a std 53 mS seawater cal solution it MUST be only the PinPoint from American Marine.There is a reason for this. A std seawater cal solution is made from KCl and the PinPoint is not and is nothing more that home made seawater @ 35 ppt = 53 mS. A std seawater 53 mS KCl will NOT work on a refract, it is ONLY for conductivity meters or Salinity meters. The PinPoint will work on all 3, be it refract, conductivity/salinity meter or a hydrometer if you have enough of it. That is how I know it is only seawater in a bottle @ 35 ppt, as it works on all 3

The link I posted was made by Pinpoint!
Should of read this before my last post on the other thread lol!

Ifeel i have started something here:lol: Boomer :?: could having my salinity at say over 40 ppt have an effect on my softys i.e xeni pulsing one

 

[Boomer]

Well, that is rather high but then again the Red Sea is that high. I would lower it and I doubt yours are form the Res Sea. So, it may be an issue but I doubt it. The usally problem with Xenia is not enogh current. They need good current to remove the mucus from them and they *seem to have a harder isssue with this than others. When Xenia are pulsating or lets say pulsating to much something is wrong IMHO.

Jim is a really nice guy, I chatted with him a long time over the phone, very helpful! Same link & info!
