Hey Randy,

You and this forum were highly recommended by the seller (tony) of my 75 gal reef tank. Hopefully you can give me some in site :)

I have a new 75gal tank setup which still seems to be cycling a little bit. I have a few zoos and chalices that are doing well,however, the PH seems to be low. I'm using the tetra strips to test the water which read around 7.4ish. I do have some mrs wages pickling lime to increase the ph. Tony recommended I drop you a line to see what you recommend...any info you can provide would be most appreciated.

thanks in advance,
Ryan

First I would like to Welcome you to R2R. Now on to your question, from what have read in multiple post, the strips are not accurate for saltwater tanks. You might want to get your hands on a master saltwater tester kit for better results. My question to you is.......... Do you have the zoas in the same tank that is currently cycling? When did you start the cycle?

Well, I'm not sure what that means in terms of alkalinity, but if it is in the range of 7-11 dKH (which I consider the goal) it is likely that the pH 7.4 is not accurate. :)

Is this test kit intended for marine systems?

i have an alk test kit coming in the mail. i'll post back once received.

yes this test kit is intended for marine aquariums.

is there any way i can start dosing safely (slowly) in case the PH is that low?

The pH is not that low (I've literally read many thousands of posts about pH and what people experience, and a reading like yours is never real in a reef tank with adequate alkalinity and aeration), and there is NOTHING you should ever dose to correct pH if alkalinity is OK.

All additives to boost pH are alkalinity additives. So what you do is use high pH alkalinity additivey WHEN (and only when) a kit tells you you need alkalinity. :)

I can believe pH is on the low side (say, pH 7.7-8.1) and if you get a number for the alkalinity measurement, we can determine how to proceed. :)

I would get a more accurate PH test and if still low I would add some macro algae.
your tank is still cycling and during that time a low pH is common.
It will rise as the cycle completes.

That'a fine value, and so the pH 7.4 seems very unlikely.

I'd just monitor that alkalinity and salinity and not mess with anything else for now. :)
