Starting A Heavy Planted 450litre Rio 400
I am preparing my 450 litre tank and came to the step that i should choose what plants should i get.
Info about tank.

Gravel - Seachem Red & Dark Mixed
Volume - 450Litres 1/2 RO and 1/2 Tap
Light - 216W (10 hours a day)
With CO2 connected to an Aqua Medic reactor 1000 for maximum efficiency and with PH controller set with 6.8PH.
I will try to dose once a week Seachem Flourish. Should I also get the Root Tablets??

Fish i am going to get are angels, bristlenose and tetras.

Plants that i am going to choose are the following. Would like some of your opinions if these are right for my set up.

Back - RIGHT Vallisneria spiralis
MIDDLE Echinodorus Amazonicus
LEFT Hygrophila Polysperma 'Rosanervig'

Middle - LEFT Nymphaea Lotus Red
LEFT in front of lotus Cryptocoryne walkeri or Cryptocoryne becketti
Middle LEFT Cryptocoryne wendtii 'Tropica'
Middle RIGHT Cryptocoryne undulata
Right Cryptocoryne Lucens

Carpet - Echinodorus Tenellus or Marsilea Hirsuta (Preffered)

Mosses & Anubias on driftwood with moss ball to fill in some blank.

Below Tank right now.

Which plants you chose I can't help you on as it is a matter of choice. I just wanted to say... LOVE the look of your tank so far and can't wait to see it finished. Love the background.

That will be lovely planted; and I like the wood pieces. A couple larger swords (Echinodorus bleherae) behind the wood on the right and the piece next to it will really add depth to the aquascape as they grow up and fan out over the wood.

You don't mention water parameters; if soft and acidic (as I would expect with CO2), I would reconsider Vallisneria, it does much better in basic harder water.

As you are dosing CO2 you will need more fertilizer than once a week. Flourish Comprehensive can be dosed once or twice weekly, and with CO2 twice will be essential. You may need more. This is one of the reasons I don't like CO2, it raises the balance level (more light and more ferts to balance). Is the Seachem substrate enriched? That will help; substrate tabs should not be necessary. Liquid will cover it if there is enough.

About substrate i have 21Kg of Seachem. Flourite Dark

and have 42Kg of Seachem. Flourite Red

I guess it is rich of nutrients. Soft to medium water with ph ranging 6.8 - 7. I will set the ph controller to 6.8.

If i stick to ferts once a week what could be wrong? Say once every Saturday?

Plants require light and 17 nutrients; these have to be in proportion to each other. Botanists refer to "Liebig's Law of Minimum;" plant growth will be affected by the factor least available. In all planted tanks, whether high-tech or low-tech, light should be the minimum factor. If light exceeds the available nutrients, plants cannot continue to photosynthesize and algae takes advantage.

I have low-tech tanks; the CO2 comes from the fish and bacteria. I balance the light (intensity and duration both matter) with the carbon (CO2) and add fertilizers (the other nutrients) accordingly. In my tanks, I must use Flourish twice a week or the swords begin yellowing within 1 week. Clearly this tells me that the CO2 is in balance with the light and other nutrients provided I fertilize twice a week. Algae is present but not to excess; I reduced the light period by one hour about a year ago and algae took a step back.

If I were to increase the available CO2, my plants would not benefit much; unless I also increased the light (intensity and perhaps duration) and other nutrients (fertilizer). The principle of balance applies in all planted tanks, regardless of the method.

You will have to experiment a bit; the nutrients in the substrate will help (I have plain gravel or sand in my tanks). The growth of the plants after a couple weeks will indicate whether or not something is missing.

As an example of the high-tech method, Takashi Amano's tanks have CO2; he uses mega light; and he fertilizes (with his own several preparations) every day in order to balance the light and CO2. Nutrients come from various sources, but the higher the level of balance created in the aquarium, the more necessary it is to supply additional nutrients. It takes a bit of experimentation to ascertain the balance.

Ok so I have to fert twice a week say Wednesday and Saturday.

About the plants that I listed do you think that they will be fine with the light I have?

Went back in this thread but no mention is made of the type of light. This is a 118g tank with 216 watts (that is a lot of light, but you have CO2 to balance--I hadn't noticed this earlier; you will absolutely need fertilization or you will have algae out of control), but no indication of the type (presumably fluorescent, but T8 or T5 or T5 HO; and the kelvin rating of the tubes).
