Ph levels pressurised Co2 planted aquarium

[brads]

Hi there,

I'm using the JBL Drop checker and over several months now I have been running my Co2 24/7 on advice from my LFS.

I joined ukaps yestarday and on looking through the forums changed the Co2 injection to come on 2 hrs before lights, and go off 1 before lights off.

I have monitored the Ph levels today and noticed that this first Ph test was taken 08:00hrs, 2hr before lights on,
Ph 6.4
@ 13:00hrs Ph 6.8
and @ 18:00 hrs 1hr after Co2 off, Ph 7.2.

Could someone explain what this means? do I have to adjust the Co2.

In the morning when I checked the drop checker it was in the green, the same in the afternoon.

Assistance appreciated.

Billy

Hi Billy! This is a thread i started a while ago (Melting Marsilea hirsuta & Staurogyne repens? | UK Aquatic Plant Society) this should answer a few of the questions you are asking. Clive really knows his stuff, and since following his advice my tank has really taken off.

Hope this helps?

Lee.

Thanks Lee,

Excellent reading, I think that's answered my question and more.

There is just one question I would like to ask if you don't mind?

I'm using the dennerle Co2 ladder, do I still require a bubble counter?

The reason I ask! is counting the bubbles via the bubble counter and watching the bubbles coming into to the start of the ladder is a massive difference in bubble count.

The difference is about 4-5 bps in the bubble counter to 1 bps going through
the ladder at the start.

I think the bubble counter/DC is only a reference, as clive states in the thread link i provided. I would use your pH profile to determine if you are injecting the right amount of CO2 or not.
