My 50g tank has been running for 15 months.

I've been injecting CO2 and dosing DIY dry fertilisers for around 10 months with mixed results.

All this while I've been working with a 2.5 Inch Indonesian lava rock substrate.

I'd like to put a 2 inch Organic Potting Soil substrate underneath my current lava rock.

Any advice on this plan? Any pitfalls I should be aware of?
