Here's my current levels.
nitrate 15
nitrite 0
ammonia 0
salinity 1.023
alkalinity 210
pH 7.5
Temp 79

I do small 2-3g water changes once a week. I always check these levels after. I believe everything looks okay, but I was concerned about the pH. It has never drop before and has normaly stayed at 8.1 - 8.3. Soo what could be causing it to drop? Is it harmful to my fish? And what can I do to try and correct it?
I know there is pH corrector liquid to buy but I didn't know if there was a more natural way to fix it... Well what I'm worried about more is if there was something I was doing wrong to make it drop in the first place. Any advice would be greatly appericated.

*ahem* SW tank, not FW.

That is pretty low for a SW tank. What are you using for testing the pH? For the first year or so, I lot of times I had to use buffer to keep the pH around 8.0, otherwise it would drop down to 7.6 or so.

The next question is about the water used for water changes. What is the pH of the new water going in? Basically you need to start playing detective and try and find the source of the low pH.
