LOW PH afyer cycle

[Max_in_SD]

I have been using the kent marine buffer to achieve a PH of 8.3 as it states adding every down but for some reason my ph does not elevate and stays at 8.3 any suggestion

Most buffers are chemically targeted to acheive a pH of 8.3 and stop. There is absolutely no reason to go beyond that. If your daytime pH is reading 8.1-8.3, you looking good. It is also not uncommon for the pH to drop fairly low at night eventually reading as low as 7.8 just before lights on in the AM.

Be very wary of making chemical additions. Buffers will also increase alkalinity in the process and can easily upset the balance between alk and Ca causing you even nore issues. Before you dose anything in the tank, always test first to see what is needed and again afterwards to see what the change was if any.

Do you have an alk or Ca test kit? If so, what are your readings?

Cheers
Steve

my mistake meant to say it does not elevate pass 7.8 despite using the kent 8.3 buffer

Have you done a good sized water change since your cycle finished?

What do you have in the way of powerheads, water flow/GPH?

Does the tank have a solid lid?

Do you know the alk and/or Ca levels?

Cheers
