i can rig something up to get light to it, the only problem is that i do not have a way to add a sump or else id have to stick it next to the tank, which i might just do in the future....

i tested the ph in the water before i added it to the tank...its about 8.4

Lets see what Pasfur or onefish2fish has to say before you go one way or the other with the macro... I still think putting it in the display itself is a pretty decent idea. You definitely don't need a sump, it just has some nice benefits to it is all. But if you can't put it under the stand or hidden from view, then it's really a judgment call as to whether or not you'd mind having a sump with all the equipment and tubes running to/from the display in plain view.

So the salt mix definitely isn't the problem! Something about your tank isn't providing the proper buffering capability to keep the pH up. Supplementation with a pH buffer wouldn't be a bad idea, but I still wonder why the pH drops so low in the tank. You did mention that you do a two-part supplement right? That should keep the alkalinity up, and help buffer the pH, so I'm personally at a loss right now as to the pH issue.

EDIT: I just checked the previous page, and you mentioned that your alkalinity reading is 2.5... that's way low, and explains the water's inability to keep the pH up. So that begs the question (thinking out loud), why is your alkalinity so low, especially if you are using a two-part additive? Let me think on this some more

using a sump with macro and having a light on reverse cycle will help pH swings. by reverse cycle i mean when the tank lights are out the lights over the sump are on, and when the tank lights are on the sump light out.

my chart says
(milli equaivalents per liter)
Low = 0 - 1.6
Normal = 1.7 - 2.8
High = 2.9 - 3.6

oh ok, I am used to the units of dKH, where 8-12 is the target range for saltwater aquariums. Sorry for the confusion!

I'm out of ideas, but as Pasfur and your pH test of newly-mixed water indicated, the tank is unable to properly buffer the pH and it drops significantly. My only guess there would be that the alkalinity is low... I know that pH, alk, calcium, and magnesium are all inter-related, but I've been under the impression that alk affects pH, calcium and alkalinity are effect each other, and magnesium affects calcium. I'll hold off until Pasfur, onefish, or someone else comes along with some ideas. Sorry I couldn't be more help

i dont know if this was asked, but what brand test kit are you using? how old is it and are you properly using it?

sorry for the multiple posts, more thinking out loud here...

so I looked up the conversion from meq/l to dKH, and it's 2.8 dKH = 1 meq/l (someone please correct me if I'm wrong!).

If you've got 2.5 meq/l, then multiplied by 2.8 you get 7 dKH. That's still a little on the low side, but (a) i don't guess that it would be so low as to cause a drastic drop in pH from 8.4 to 7.4, and (b) why does your scale show that 1.7-2.8 meq/l is "normal", when that maps to 4.76 - 7.84 dKH? I pretty much know for a fact that dKH should be 8-12 for a saltwater tank, so somethings amiss here as well.

Anyways, still thinking, but wanted to add this info to the thread

its possible the test kit was sitting in the store for some time, they do have a shelf life. if you still have the box see if you can find an expiration date and even though your salt is 2 weeks old doesnt mean thats not a bad batch either. idk if anyone asked but have you tested pH of the water you use to mix, the salt water prior to adding it to the tank and then after its added to the tank?

your going to want to pick up a ca and mag kit at some point. i personally like salifert (IMO the best one but expensive) and API (IMO a good one and cheaper) but elos is of equal quality to salifert too.
mag, ca, alk and pH are all tied together so having stable readings is key. it will be easier to adjust 1 if 3 are at normal level. the issue is you want to slowly buffer (over days/weeks) to raise the low levels to avoid shocking anything in the tank. pH buffers IMO are garbage, they will raise your pH then drop it causiing it to be all over the place. your best bet is fixing the problem at the source of the problem.

yeah, he tested newly-mixed water, and it came out with a pH of 8.4. So either the water or something else in the tank is unable to buffer that pH.

As we just found out, the alk is a LITTLE low, but not completely out of control. Do you think a dKH of 7 would be low enough to let water with a pH of 8.4 drop to 7.4 (assuming he's never had a bad batch of salt mix, and it always mixes to 8.4 to start with)?
