pH too high... (almost 9)

[wilsontantw]

Hi people,

my pH reading is close to 9!!!

Can anyone recommend something that can gradually bring down my pH to the desired level of 8.3?

Gosh, now i know why my true octo and GSP are not opening.

More importantly, how do i stabilise it at that level?

TIA.

do a water change. what do u measure ur tank pH with, last time i also have this false alarm that my pH is overly high with my pinpoint monitor which require caliberation?

if not, normally pH will drop with time from my experience.

anyone using ALPHEUS distilled pure drinking water?

the pH is app 9 using my pH pen

Wow!..I din know Alpheus distilled water pH can be so high....like that should be bad for human consumption...should be neutrel at 7? no?

Coz distilled water should be pure, free from calcium and dissolved minerals....so pH should not be so high leh?!

initially i thought so too, calibrate my pH pen, test, same result

any bro can test and confirm?

i recently did a rescape + 100% water change. (basically restarting the tank).

afterwhich, i bought a true-octo which is not opening well, and GSP also didn't really open.

My light and waterflow is pretty decent now... so i suspect something is missing.

calcium, magnesium, po4 all okie. so i suspect it's pH.

t-loan a pH pen (not properly calibrated), but from some 'estimation' i realised my tank is higher than normal.

My friend's tank is operating well (everything opens nicely), and he brought me some water to 'calibrate'.

my pH pen measurement reads: 7.1 on his tank (which = 8.1-8.3 actual reading)

And my tank reads: 7.8, which probably means 8.8-9 actual reading!

that's very high le.

Just wondering will those pH buffer powder lower the pH? or raise it?

hmm... maybe this explains it! coz im using Alpheus too!

will go back and confirm it tonight.

what salt are you using?

some salt lower the pH to ideal range, eg coralife

ALPHEUS + tropic marin salt = pH 8.8 based on my nano tank

ALPHEUS + coralife salt = pH 8.4 based on my 3 feet tank

wah! you basically confirmed my readings bro!

Alpheus + tropic marin (pro-reef) = pH 8.8-9!!!!

in ur opinion, do i need to buffer it lower? i suspect that this is the element causing me to lose my true octo! (very sad sia... i paid so much for it!)

Post some pics of yr tank and octo will be better for lau jiaos (referring to those experts) here to diagnose the problem for you...meanwhile you can add some calcium buffer to stabilise yr pH or change yr brand of DI water lo...i used ntuc & life brand.

i use 3-5ml of pH down to lower the pH to 8.3

no issue with my fake octo

hmm... okie... will do that later tonight.

but for now, guess i'll try to use the pH down.

bro dnsfpl: this pH down thing is readily available at LFS yah?

yes but be careful of your dosage

3ml is enough 6l of water

get calibration liquid for your pH pen too

yeah... im planning to buy both from the same place.

But i can't believe a small package of calibration fluid costs $8 bucks!

this type is used once and throw away type right?

btw, can PM me how much is the pH down (just in case i kena 'carrot head')

[dnsfpl]

i forget how much but should be app $5

as for the calibration fluid, i also paid app $5, enough for 4 calibration

all at c328

You said you did a 100% water change. Could be new tank syndrome.

Erm... my combo is TM Pro Reef Salt + Alpheus Distilled Water = 8.1 pH. Its a brand new pH monitor that I bought only 2 weeks ago, which is calibrated with the 2-point calibration (ph 4 and ph 7).
