Increase PH?

[uriah]

Hey guys and gals I need a little help. My PH is at 7.8 and wondering if anyone knows how to increase or what affect it would have on existing livestock.

CA 480-500
KH 195-210
NO, NH & PO all 0
Salinity 1.023
Just did a 10 gallon change on my 55g

Thanks for your help!

What time of day/night are you taking the reading?

[uriah]

around 5pm CST. Took two readings just to be sure, same thing...

[Texreefer]

is the 195-200 reading PPM since your expressing in KH? if so that roughly 11dkh or 4 Meq/L. those #s are getting close to being too high. I would guess your Mg is a little on the low side and some precipitation as a result of this imbalance is cause a reduction in Oxygen in your tank which in turn will affect your ph,, use the online calculater in the do it yourself forum if you want to dose a bit of baking soda to help with the Ph, but regular water changes, some extra water aggitation at the surface and maybe the addition of some magnesium should help solve your ph problem.

You are correct in you assertion that my alkalinity is high and your assumption that I was reffering to PPM. I dosed about 6 oz of magnesium last week. If reg water changes and magnesium will help, that would be the easiest route, but would the low ph significantly impact my coral growth or have any other negative affect on my livestock?

yea low ph can significantly impact coral growth and can also kill ur fish.....my ph had dropped to about 7.6 n killed some of my livestock......theres some ph buffer u can buy at an lfs....thas wut i did....everything returned to normal...all other parameters were not affected...

[uriah]

I am going to test it again in the morning and go from there. The ph tends to fluctuate and drop at night...

[JoshOdphi]

yea run it again c where ur at....if u still need that buffer then go ahead and add some...its pretty cheap anyways....i keep it jus in case anything causes my ph to drop

[ballardjr2000]

Your PH will be the lowest before you kick your lights on in the morning. and the highest before lights out. also a quick cheap way to raise PH baking soda

[JoshOdphi]

oops...thas right baking soda will do tha trick...ur right jon..i keep forgettin...
