Default New to marine

Hi All

I just set up a small marine Pico tank ( IQ5 ) and found that the PH is persistently low ( hovering around 7.4-7.7 ).
What should i do?
Have tried adding Seachem marine buffer but doesn't help much.

Tank is currently in the 3rd week of cycling with LR, biohome and ceramic chips.
I have added 1 bag of coral chips ( those $1.50 per pack ) too.

Current parameters using API test kit

Ammonia = 0
Nitrite = 0
Nitrate = 0
KH = 12dkh/214ppm

Is the parameter ok?

Hi thanks for the advice.
I am using API tester for KH and Tetra tester for PH.
Will try out your suggestion.

Strange combination of high KH and low PH...normally high KH means low PH swings...
Maybe check with another PH tester? 7.4 and 7.7 seems very low..sometimes they type of salt you use also plays a part. maybe change salt.
Seachem buffer will buffer up to 8.3 and quite safe...pump it up and see what happens... remember that PH will go move up and down during the light cycle ( no light the PH will drop)...maybe your tank is still cycling and there are still bio dying/rotting that causes your PH to be so low.. since you are still cycling, wait and see what happens as 3 weeks is still quite short.
Anyways small tank always difficult to maintain a stable parameter, regular water change seems to work but quite tiring.

happy reefing

Thanks all for the advice,cycling should be completed and LS already in the tank.
1 tomato clown
1 fire dart fish ( should be this name )
1 cleaner wrasse
1 salifin benny ( not sure spelling )
1 cleaner shrimp.

LS were added at the rate of 2pcs at one time within 1.5week.

Last readings on parameter :
NO2 = 0
NO3 = 0
Ammonia = 0
KH = 10dkh
PH = 7.7>

Not sure whether test kit accurate or not as some readings seems too good...

The pH of the water (its acidity or alkalinity) should be between 8.0 and 8.3, and can be conveniently determined with a pH test kit. (Make sure that you use a saltwater pH test kit; freshwater types, although covering the relevant range, will not show a true reading.) A falling pH - a normal tendency in the marine aquarium - can be counteracted by using calcium-rich coral sand as a substrate. Alternatively, pieces of seashell (another source of calcium) can be placed in the external filter.
