Its definitely not constant, it would be really nice if it was though 😄If ph drop in the first hour of co2 on is 0.5 can I calculate that the ph will drop at the same rate for the next hour?
I.e. 2 hours = 1.0ph drop?!
Will that rate slow as the ph drops or remain constant?
Morning all,
Thought I would follow up but also ask advice once again..
So plant health is really good now, missing compounds were added to my fertiliser or front loaded and plants looks really healthy... I'm pleased.
Co2 must still be off, ph drops from 7.6.. to 6.5.. by lights on but then continues to drop throughout the photo period - I'm really struggling to get a stable pH.. any tips?!
Hair algae is persistent is this because the ph is continually dropping during lights on?
Any help appreciated
Chris
At the moment it gets down into the 6.3..
I have added a wave maker and at 14:00 when I lights come on today I will play with surface agitation and see if I can reduce the drop
I'm not sure I'd be too concerned about a 0.2pH difference - the wave maker might be overkill, I'd just maybe raise the lily pip a little.
Hmmmm, so the hair algae is not caused by a dropping pH?
Twinstar 900S turned down 50%
The light is on roughly 75%
