newbie- ph= 7.8 and speci grav= 1.019 what to do?

[rkmayphd]

Relatively new to this. Water is testing fine to this point. Today my ph and specific gravity are a little low.
Readings
Ammonia- 0
Nitirites - 0
Nitrates- 10
Ph- 7.8
specific gravity 1.019
It is a 46 gallon fowlr been up for about 6 weeks. Using RO for 5gal water changes every 10 days.
What should I do to raise ph and specific gravity?
THANKS

There is salt in that RO that you're adding right? :notsure:

YEs, I should have been more clear. RO only for topoffs- salt mixed for 48hrs prior to adding.

To raise the sg start adding salted RO for top offs.

Odd to say the least... It sounds like your water used in the changes has a lower salinity than you want and it is slowly lowering your tank. Do you mix your own or purchase from a LFS?

I mix my own. I am not sure wha tis going on. What about the ph?

I watched my PH drop due to food and such that was caught in various filters and was breaking down.

Add PH Buffer with your water changes. It works for me. Just keep close check not to add to much.
