a friend of mine got hold of a established 200g tank with 50g sump,powerheads,huge skimmer,loads of corals,LR
,sensors wave maker etc.
he had a problem with the controller which I have sorted out by calibrating the 2 ph sensors, a redox sensor,conductivity sensor.Ok the thing is I dont know how to setup the co2
.At the moment one ph sensor is in the sump and reads 8.16,the other is screwed into a reactor and is reading 6.4.
On the controller when you go into the parametres you can switch on a piece of equipment using a plug bar connected to it,in the ph settings you can setup the co2
to be switched on,but i dont know what parameters to inputor when the co2
should be used,i cant remember the make of controller,Can anyone help please????
