PH level can't go beyond 8.1

[Patrick]

Once again need some advice from the expert bros

Bought a PH monitor put probe in tank meter showed 7.7. Added Kent Marine KH buffer 3-4 teaspoons mixed with water. After added twice over 2 days it raise to 8.1. However, addded 3 more times (same dosage) but still at 8.1. Any bros know the reason?

Mine is 5x1.5x2 ft. Fish with corals. With a 3ft sump, H&S skimmer, Rowa phos, PureII and Polyfilters.

Hrmz, my Ph never goes beyond 8.2 also. I think improving your flow would help abit? Im not really sure too.

Thanks bro. I just started to drip another 4 teaspoon. Hope to raise it to at least 8.2. Have Seio 800 and Seio 600. Yah thinking of increasing flow may help. Thanks for your advice.

is yr pH meter calibrated?

What time are those readings taken, the 8.1 one.? Is there a nite time pH reading or a range of pH?

Hrmz, mine fluactuates between 7.8 to 8.1. I think my low Ph has something to do with insufficient flow in my tank. Will adding another powerhead help?

I've been using a product to raise my Ph, but would like to find the root cause of low Ph, any idea what might help? Im running sumpless and using a cannister.

Decided to break the seal to calibrate the meter. Put in 7.0 solution showed 6.8-6.9. Touched the dial only and it showed 7.0 After calibrating now showing 8.3 up from 8.2.

I read some high level of detritus caused by fish poo-poo and unconsumed food, dead LS will cause PH to drop and hard to maintain.

Thanks to all bros for your advice.
