I have tried to get good flow around the tank so just before I buy the plants above would the current setup I have be able to grow the plants listed above?
Hi,
Well of course. There aren't any plants that
cannot be grown with this combination. It's not how much light you have that determines success. It's how well you are able to provide good flow and distribution.
Saying that you have good flow around the tank is easy. Actually having good flow/distribution and CO2 dissolution is not so easy.
Success growing these and any plants will be strictly dependent on CO2/flow/distribution as well as your nutritional program and maintenance habits. There are so many factors it's difficult to predict success with having very specific details. The only details we have so far is that you have hard water, which doesn't really matter, that you have 200L and that you have a bunch of lights. These detail are relevant within the context of the more important details as follows:
We do not know, for example what kind of filtration or supplementary pumps you have. We do not know how the pump/filter outputs are arranged. We do not know how you are dissolving CO2. We do not know the diameter of the hose or the type and quantity of the filter media, which affects flow. Maybe you have already optimized these factors, as you mention, but we cannot say for certain until we are able to assess that information.
These are the things that matter most.
The only effect more light will have is to make things happen faster, but faster is not necessarily better because bad things happen in the tank faster than good things.
Inexperienced hobbyists are always worried about whether they have enough light to grow this plant or another, when actually 99.999% of the time they have way too much light which sets up a series of events that contributes to failure. The industry in general programs people to worry about this so that the hobbyist will spend lots of time, energy and money buying lighting products, which they all seem to have a stake in. The hobbyist is told that he must change his bulb regularly, so he/she spends more money on absurdly priced bulbs that cost no more to make than the bulbs at Tesco. We are told that only specialist "Plant Bulbs" are satisfactory thereby ensuring that the high bulb prices can be justified.
You would be wise to start asking the right questions, such as:
Do I have enough pumping power?
How should I arrange the filter outputs?
How much and often should I change my water?
How should I dose the water column and what products should I use?
What is the best CO2 dissolution method for 200L?
Should I be concerned about water chemistry?
Should I trust test kits?
There are about 100 more questions that are important to know the answer to.
The "Do I have enough light?" question should be down at around number 101.
Cheers,
