Hi Ceg, a very quick update, I tested the hardness of the sera PH 7.0 calibration liquid and the reading is off the scale. the liquid is very, very hard. The tap water I have here is soft KH 3-4 and PH 8.0 (it's desalinated). Can I use this if I check hardness and PH prior to use? I know it's...

Hi Ceg, Another question I am afraid..... I managed to get a jbl drop checker which is pretty amazing given the stuff thats normally on sale here, I bought the only two infact left in the shop. Problem is I can't find KH4 or dionized water. I am thinking to use some Sera PH 7.0 ph meter...

Thanks for the information Ceg, It's really interesting and helpful. I have now started running the co2 at one drop per sec, lighting time only and monitoring the PH (for reference / callibration only) fish look fine, (no surface swimming / lethergy /disorientation) PH has dropped from around...

thanks ceg, I am now starting to add co2 as per your comments re PH 3. My fear was due to most books like bede atlas which give a range of PH for different fish. The only thing I am still thinking, is it would be good, if possible, to utilise the ph meter and solonoid I already have to...

Just a quick question, is their a way to control co2 using ph and solenoid. I do understand that there are other reagents in the water affecting acidity so a direct check is not possible, however, I was wondering if you are able to use a factor to control.....for a rough example: 1) run tank...
