Just an update.
This has been running since the 5/7/16 without any issues.
Water is crystal clear plants and all livestock been happy.
Don't need to do water changes every week as ammonia levels are 0-0.1 even after two weeks which I am happy with. Only issue I've had since is having the time to enjoy watching the tank mature even more since adding more fish.
Just need to keep on top of the plants now as got to keep trimming and seating the new growth elsewhere as it ends up like a forest within two weeks may have to reduce co2
to keep the growth down but only when a fiends tank is full of the plants too lol
bottle still going after 7 weeks with a 70mm bazooka diffuser going from 7am till 11am then 2pm till 8pm on a timer. As it was getting too high of a dose of co2
so just set timer to adjust the dosage on the 240l tank.
Hope this help people as its the best choice to run two filters as only need to take one offline and change relevant media. And not much of an impact on water levels.
