Right the ph seems to have settled now although I will have to turn it off soon as the odd one or two fish are at the surface now.
I have adjusted the pumps, and after rescuing my micranthemum after it decided to uproot and spread itself around
My readings are as follows and it does not seem quite right.
Before co2.........................................................7.4
1 hour after co2 on and 1 hr before lights on....7.1
Lights on............................................................7.0
Lights on plus 1hr..............................................6.9
Lights on plus 2hrs............................................6.8
Lights on plus 3hrs............................................6.8
Lights on plus 4hrs and co2 off.........................6.8
So do I need to turn the co2 on earlier? Also I have just noticed today but have heard it on regular basis...a regular burping sound but today I took notice.
What is happening is on a regular basis the last hole on the spraybar is pushing out excess larger bubbles which I assume is co2. Why it is doing this and how to solve the problem I have no idea.
My wife has also agreed that, if it would be of benefit,. I can get an external filter with 2000 lph (but only a cheapo APS one).
She has also agreed to an overtank system at 2 x 39w T5 if it would be of benefit (but only a cheapo APS one.
So would these two changes be of benefit, or of little use?
