Do you all test your PH regularly. I think it is suppost to be around 8. Mine is at 6.5. How can I increase it to the correct range, or will it do this in its own as animals are added?

it should be 8.0-8.3, 6.5 is WAY low, I would not add animals to a tank with that low pH, test your tanks hardness, get that around 10 dKh by adding SMALL doses (like a pinch per 10 gallons) of baking soda to high flow areas. Once you get that stable, pH should start to rise.

Yeah in a salt tank 6.5 is totally unacceptable for most organisms I know. What salt mix are you using, and what is your SG?

How old is your test kit?

PH is measured on a logarithmic scale, so a PH of 6.5 is about thirty (30) times more acidic than a PH of 8.0. Definately fix the PH before you put any animals in there.

My test strips might be bad (using the ones from my acids bases science lab) I am using instant ocean, and have about 1/4 of my tank live water. I already have pods and one shrimp living fine for about a week and a half. My SG levels are in standard range. How do I test for hardness?

There are a wide variety of test kits, either liquid or dry reagent, as well as test strips..... (KH = carbonate hardness)

I would say the basic think wrong is the test you are using. :biggrin2: You need to use a test kit designed to work with saltwater because saltwater can do weird things to test kits.
With that stuff living in your tank, I don't think you have much to worry about.
What is standard range for SG and what actually is your level and how are you testing?
I don't think hardness matters much in a ceph tank. Alkalinity levels are important for stony corals.

Also, in general, be careful chasing numbers and adding stuff to chase those numbers. Often, an additive will not actually 'fix' the numbers you are looking for, and will only bounce the numbers up and down.

Invest in some quality test kits, API, Salifert, Elos, and you'll be happier.

Thales,
My RO/DI water is ALWAYS at about 6.0 without buffering and does not come up much with even the reef salts (which is supposed to be for RO water and produce a higher PH). The neutral reading is expected from RO water. Supposedly, the neutral water will adjust if you add it to water with a different PH (either up or down) but my tank PH drops if I do this without first buffering the new RO.
