ph control

[Lucian]

i invested in a RO System , to see if my Ph would stabilise , it worked for me

 

supposedly , because the resevoirs are low , the water authuoritie here add something to the water that makes the seddament settle , only to save the theyre pumps from high maintenance ...

 

 

blah blah blah , yeah im off me fuggin bean !

I bet you are using Tap water ; You must let it sit for at least 24 hours min to let the chlorine dissipate as it dissipates it makes yor ph climb like mad .I had the same problems now I sterilize and let all water sit for about 24 hrs before letting it enter my set up.

EC 0.8 straight out of the tap yep that water's hard.

If this is coming from a ground water source the high level 50 - 200 mg/L carbon dioxide need time to escape into the atmosphere till the level reaches 0.5 mg/L.

The pH will continue to rise to a level dependant on the groundwaters bicarbonate HCO3 content

By aerating/tumbling the water the CO2 is returned to 0.5 mg/L faster so that the Ph level can then be set
