Hi Guys,

I am worried about the PH on my discus tank. My normal readings are aroung 6.5. However last night i got a reading of at least 7.5. I immediately did a 50% water change and another 20% tonight. Cleaned both my filters etc. However i am still getting a very high reading.

Firstly, what would cause this to go so high all of a sudden? I regularly water change and clean the substrate and filters.

I have also added more bog wood tonight, though this has been soaking for over three weeks, is this going to make the blindest bit of a difference after so long soaking?

Will my discus cope until tomorrow until i get some peat for the filter and fresh bogwood?

Thanks guys

your fish should be ok for now .......try to think of anything added to increase the ph ?

do you have a ro unit neil? if you had one you could just use more RO in the water changes .

not sure why it should suddenly jump up, just watch the fish and monitor what happens over the next few days with waterchanges

what are your ph readings for your tap water and ro water and do you add a buffer to your tap water to get it to 6.5.

i agree with rob about adding more ro water but you must find out what readings are of water going in

depending on this will depend on what ratio/mix of ro/tap water you will use

what i did was measure ph of tap and ro and then had found a mix ratio to get my ph to 6.5 and also add a little bit of buffer 6.5 to stabile it.

hope this helps
