PH & KH low

[gregrobjones]

My tank is 2 months old and I do water change every week for 250 litre tank of 25 litres. My PH & KH are low after a day and I do not know why?

Fully cycled tank.

Thanks Greg

What is low?

New tanks are often unstable. Even if they are fully cycled, elements are often harder to manage. My advice would be to wait a little longer to see if things change. But, if you are really worried about the pH being too low it try dosing some kalkwasser or 2 part.

What salt? At what salinity? And as stated, what actual KH? And what corals/clams and sizes do you have?

pH is not a concern.

Corrals are frags touch, frogspawn, single head ducan, bright yellow LPS (cannot remember the name), zoanthid, toadstool and 2 bubble tip anemones for my clowns wish never got them now keep moving after a few weeks.
