Hi again, Sorry for the late reply!!
Thanks for all your help! It has given me lots of advice on planted tanks, especially to a beginner in this topic, like me! I still have a couple of questions, following up your useful answers:
1. In terms of the either a tall or a long tank, the tall tank is 30x30x30cm (a cube), wheres as the longer tank will be 40L x 25D x 28H- which will give a overall larger tank. I intend on doing a jungle style with a mixture of plants, so what do you believe to be the one which will look aesthetically appealing and more beneficial towards the Plants, in a jungle setup??
BOTH TANKS ARE AROUND 8/9 US GALLONS.
2. In both tanks/ both come with an 6500k
18w PC bulb. Will this be enough to grow a wide variety of plants in a jungle cube or would a 20w bulb, be more beneficial?
I intend on using diy co2 and see how it goes, but will probably go back to liquid carbon after the first couple of weeks and will fertilise weekly/ daily, using a liquid source.
HOW WOULD I GO ABOUT MEASURING HOW MANY CO2 bubbles per second, in a tank this size?
Finnaly, the filter is a 600lph hang on filter. Will this be too much for a tank of this size, as I will want to grow a variety of plants. Will this be too strong, for such a tank?
I have taken a look at the fluval edge, and like how minimalist it looks. However, could I keep a Siamese Fighter/ betta splendas, in a tank like this due to a lack of surface area or not?
Once again, thanks for your help.
