Thank you so much @nabokovfan87…that’s fantastic information.
I watched the video from Irene that was linked above…very useful and I will watch it again to wrap my head around her advice.
My tank is a 47 gal planted with anubia, sword crypt and wisteria, all of which are actually growing well. No C02 - other plants such as Val and grasses did not grow (assuming due to no C02). I am adding ferts but on an ad-hoc basis - I will do this regularly moving forward.
Thank you for your light settings - extremely helpful, as well as the link to the fluval thread.
I love that this hobby keeps on giving - it is extremely satisfying creating an ecosystem and keeping fish happy and healthy.
Kind regards from sunny Melbourne!
