PH dropped

[Danno]

I also am scratching....

Ph at the tap?

7.....iirc can the crushed coral not loose its 'usefulness' and therefore need replacing as and when?

 

[Danno]

also do certain types of stone/rock not affect the ph....?

 

[Miguel]

Nope. I do not think so. Unless your rocks have crevices and brought worms, etc in it..

Is it xist, by the way, those black slates?

By ph in the tap i mean measure the ph of your tap water.

 

[Danno]

ph at tap is 7, no slate stuff just large pebbles from riverbank, used the same type in the past with no problems

 

[Miguel]

I am lost. Water change a couple of days ago...no excess feedings, no excessive organic matter.

Does your water usually stay at 7... You measure it often? You measure it before you do the wc's and it is around seven?

ill be honest miguel and admit that i don't test religously every week, i never have, just every few weeks and its always ok so are the nitrates nitrites and ammonia.

 

[Miguel]

Then do not worry. It might be the usual pattern.

What fish have you vot in there?
