Hi Isaac,
You should measure an hour after the CO2 comes on as well.
The graph should read peak pH level before CO2 is injected[together with lights on] and begin to drop once it's supplied, drop to the lowest point and rise again as the plants start to use the CO2.
I forgot to add in my earlier post that Brighty K is alkaline. It helps keep the acidity down if dosed daily for new setups. Old setups like mine I skip a day or two since I'm lazy.
To remove hose, I cut a small slit on the hose about 0.5-1 cm, with a little bending & pull it will come out easily yet not come off easily when in use.
Some say to push in the then pull out. I tried before but didn't work.
I just cleaned my Cal Aqualabs diffuser yesterday and I was very afraid to break it.[dup dup, dup dup-heartbeat sound] Safely done-phew! I've broken two ADA diffusers before-Beetle 50 and the nano version so this was indeed a tense moment.
Speed controller G is a device to control the CO2 flowrate. Install it in series after your solenoid/needle valve and before the bubble counter/check valve. Turn the metal knob to increase or decrease the CO2. Much more easier to adjust than the stiff solenoid needle valve. Note: It will not work if you don't turn up the CO2 from the needle valve a little bit.
I bought 3 but damaged one with a plier.
ID ten T error.

'Olbies' like me who are already long into the hobby who have seen a lot and already despise DIY and shoddy made things.
Of course one cannot pursue this hobby without money and one must always have something to target for.
For starters as Blue says, you can always try out with modest kits and later on upgrade once you have the skills but no harm diving right in if you can afford it. ADA system is made for newbies[albeit richer ones]. Use to be difficult because we didn't understand Japanese and how it's meant to be used but not so anymore.
I used to rescape and move rocks around in my Aquasoil setup before realising MUCH LATER I was dealing with soil pellets! DOH!
