Hi all, I've posted a couple times about co2 and had some really top answers so far so hopefully you can aid me again.
I've a 60litre tank,medium to full packed with plants such as HC, rotala bonsai, vivipara, Cryptocoryne lutea. Quite slow growing a lot of them.
I was told to set an initial rate for co2 which I did. 2bps and see how long it took for the co2 to drop say 0.5 of a unit. I did so and set my timer for 2.5 hours before lights on.
I bought a decent ph pen and took the readings throughout the day. My initial ph was 7.3 before any co2 was added. It only dropped to 6.8/6.7 I think at this rate at its lowest.
Since then I've tweaked co2 and left it for day to observe unit drops. It's took me about a week to get a 1unit drop but it's a rate of 4bps. As I've read this is a lot of co2 for my tank.
I have good flow using a fluval 305 canister filter at its highest flow rate as it's connected to a inline heater and inline atomiser so I figured flow rate would have slowed to what's said on manual. I can visibly see co2 reach bottom of tank and work in a circular movement around tank.
I just want to know wether there's something a miss with what I'm doing with amount of co2 added as I'm worried this much is going to affect my livestock when I add them in couple weeks.
I took my kh and gh readings to see what the buffering was like within tank water
The kh took 12 drops and gh took a whopping 23 drops of solution to change the colour needed. Could this be affecting my limited drop in ph?
Can I run at this rate of bubbles or lower it?
I just feel that if I'm throwing too much co2 at my tank for no reason then I'd like to know so I can make a change before livestock is added.
Cheers
