Hi guys, this is my plan for my Discus project – any suggestions welcomed  Please let me know what you think.

Tank
A seavision custom built 36x24x24 (349.2 litres) with vinyl backing (what colour background?)
Lighting
Equipment: “Arcadia Classica Marine 90cm – 120cm stretch LED bar” with dual light mode. Now I’m thinking ill need two of these across the length of the tank?

Water change
Equipment: V2 Pure 50 Advanced Reverse Osmosis System with TDS Monitor
Regime: Water change - doing a 18% weekly change - 20% RO and 80% tap water which is approx 60li water total. Which is approx 12li RO & 48li tap. Those figures will work for me with tub size etc

Additives
TMC AuqaGro Nutrafeed 500ml plant food (Directions - A minimum of 10ml per 80 litres of water per week). Regime: 40ml per week
API Stress Zyme – 118ml (5ml treats 8.3 gallons of water). Regime: 45ml dose every ??
Would I need any CO2 for plants? Not looking to heavily plant to begin with.

Filtration
Equipment: Fluval G6 External Filter (For aquariums up to 600 litres)
HTML Code:

Stage one of the Fluval G Filter process is mechanical with the high capacity prefilter cartridge, unlike other filters, this features a NO bypass system.
Stage two of the process is the chemical stage with the high contact chemical Tri-EX cartridge which accepts bulk or disposable media cartridges
Stage three is the main biological media baskets for the Fluval G Bio Nodes. High capacity biological media which is stored inside the main filter housing.

Heater
Equipment: Fluval E 300w Advanced electronic heater (up to 375li aquariums)

Circulation
Equipment: Aquael Reef Circulator pump 2600 (Not powerful but I’m not looking to make waves – just a bit of gentle water circulation). Just one of these should be fine?
