PH low Gravity High

Okay so my Ammonia levels are at 0 or 0.2 cant really tell with the test kit I am using and Nitrites are at Zero

Tank has been up about 6 weeks,

But my PH is only 7.8 and my Gravity is 1.028

I made a post about my Gracity issue before and it was suggested I add RO non salt water which I have.

Not sure what the best way to tackle this and looking for suggestions

How to Raise the PH level while lowering the Gravity

Checked the temp its stable

I have three fish (two clowns and a Cardinal and Cleaner shrimp)

Continue with water changes??

Chemical PH adder?

Any suggestions would be appreciated.

A little impatient today, eh?

Lowering gravity and raising pH at the same time is a tough one. Are you measuring your gravity with a refractometer? If using a swing arm hydrometer, then you should probably invest in a refractometer to make sure what your gravity truly is.

But assuming your SG is really 1.028, I would probably just do some water changes with lower than normal specific gravity water. You can calculate out the expected "after" SG based on your PWC water and the volume you change. For example, say you're changing out 20% using 1.022 then your final SG would be...

(0.80 * 1.028 ) + (0.20 * 1.022 ) = 1.0268

... where the "0.20" is the percent you're changing and the "1.022" is the PWC water salinity. I wouldn't drop more than 0.001 in specific gravity per change... preferable half of that.

If you're trying to keep your pH from dropping any more, then doing PWC with more dilute salt water than your target is probably best. That way you get some buffers in the water. Once you get to your target salinity, then you can see where you're at with the pH and go from there.

You really need to verify salinities when doing stuff like this. I have a hunch you don't have a refractometer? If you don't, I wouldn't start changing things until you know darn sure what your salinity really is.
