what is the PH of your tank

[jhutton]

just curious what everyone keeps there ph at

curently i am able to keep mine from 8.2 to 8.4
with my controller, is this to high, to low. is the PH swing too
much? just curious

i have not been getting good polyp extension or growth
with my milipora but other corals are fine with polyp extension
but growth is still very slow compared to the past
just trying to figure out why

thanks

I like mine to be on the high side, 8.3-8.4.
What is more important to me, because I usually don't test Ph is SG (1.025), Cal (480), Alk (12 dkh), and temperature (78-79). If you keep your tank close to these, It WILL thrive. There is no other option, stability is the key.
Polyp extension is a sign of a healthy coral, which takes time to achieve and maintain if constant environmental levels are maintained. One drop in alk or temp, can impede this, and undo all of your hard work.
One piece of advise I can give, is if you do a two part, Dose in the am, or if you can dose 1 hour after lights out, and 1 hour before lights up. That should help eliminate any Ph or Alk swing.

Good Luck, I hope they start popping for you.

Mine stays in the 8.3-8.5 range.

I keep mine at night the low 8.16 and 8.28 with the the lights on. I use 2part doser and dose alk at night for 5min every hour. From 2am-12pm. Hope this help you.

7.8 to 8.4 is acceptable pH. Its better if the pH is above 8.0. But if you have a lot of large organisms that consume high amounts of O2, its hard to maintain a high pH.

Mine is around 8.3 when the lights are on and 7.9-8.0 at night.

If your tank is fully aerated you can adjust the pH by increasing alkalinity. Its the relationship between CO2, pH and Alkalinity.

You can read this article at reefkeeping to get a better understanding

your pH is fine. Just use other equiment and see of it gives you the same reading. Those probes can give you a false reading.

7.9 to 8.1 for me.

Honestly, I haven't monitored mine for years. Everybody's happy, so my philosophy is why pay for equipment which will just cause me concerns based on a number which may or may not be relavant. I'm not recommending this approach unless you've got a tank's that's been stable for a year or better, however, so don't interpret my posting in the wrong way.

Interesting point, Dave.

Mine is usually around Rhetts... 7.9 to 8.05 or so.

I'm with Dave there! Wasn't there another posting about high co2 levels within the house changes the PH levels? That's why people were drawing in outside air into their skimmers. My back door is always open and close constantly everyday putting the dogs in and out in and out. Plus I have a lot of house plants. I'm not too worried about that...

8.0 - 8.2 for me consistantly
