Is there possibly any place to go for CORRECT information? I’m wanting to stock my small low tech tank with plants... I look up the same plant on different sites (even this one, sorry) and the same plant is easy/difficult, low light/ high light, needs co2/doesn’t need co2 and on and on and on...really?!?! At this point I trust no one, no site but unfortunately don’t have the $$$ to experiment with buying and watching it die. So frustrated!!! I am now watching a $22 tissue culture of Pigestomon helferi go to heck. So sorry for this rant, I realize as a ‘new’ member I haven’t earned the right... but my loss of frontal cortex filtering convinces me otherwise.
But really, whom do you all trust for plants and their knowledge of their needs? Thanks!
I've killed my fair share of plants over the last 15 years and learned what works for me and doesn't.
Some people will report that a certain plant is super easy to grow you could put it in the toilet and it grows and they bring it home put it in their tank and it dies. I've always been able to grow crypts for whatever reason, I guess we get each other, some stem plants that others have a lot of luck with I kill in no time
Advice I'd give is stay away from red plants. They look great and they're usually more expensive and also high maintenance as they need CO2 and high nutrients and lots of clean water. All those fancy tanks one sees on line most are set up for competitions and torn down a week later or aren't suitable for fish for long periods of time.
One can have plenty of thriving plants without CO2 they just won't be bright red.
Few things I've learned over the years of killing plants.
Plants feed 2 different ways, through their leaves in the water column and through their roots in the substrate. Some plants like swords are heavy root feeders while others like ferns are strictly leaf feeders. Find out how the types of plants you have feed and then feed them accordingly liquid fert and root tabs Having said that some plants consume a higher amount of a certain nutrients than others. For instance Vallis are pretty fast growers and pretty easy to grow, they also require a fair amount of calcium to their roots to thrive. If one is growing them In really soft water with an inert nutrient low substrate they will struggle.
Other plants like Swords are heavy nitrate and ammonia feeders, they consume most their foot through their roots about 70% the rest through leaves. Most water that has fish in it will have enough nitrates in the water column but if the sword doesn't have available nitrogen in the substrate to it's roots it's only getting about 30% of the nitrogen it needs. Find out what your plants eat and how they eat it. The easiest way to accomplish this is to provide all 17 nutrients to plants in water column, and substrate. Shoots and roots. When o e or more nutrients is deficient plants will struggle and algae takes hold . When all nutrients are net or in excess plants out compete algae for nutrients and a lot of plants will store the excess nutrients.
Get a comprehensive liquid fert, flourish comprehensive is good. Get comprehensive root tabs, flourish makes good root tabs as well.
2nd thing I've learned is water circulation. One can dump all those fertilizers and nutrients to feed to your plants but they need oxygen and water movement to carry them to the plants. Photosynthesis is an exchange of gases under water as well and It needs water circulation to absorb nutrients and exchange those gases. Water circulation and highly oxygenated water is key.
I have 3 10 gallon filters on the back of my 20 gallon tank to make sure I don't have any dead spots in my tank.
3rd thing I've learned is lots and lots of plants help plants grow, the more fast growing plants the better as they outcompete algae for nutrients which keeps the algae off the slower growing plants and enables them to grow without competing with algae, let those fast growers compete with algae, floating plants are great ammonia traps and great for out competing algae
Lastly none of it matters if ones light source is out of whack as light is the engine of photosynthesis. Most important measurement for light in my opinion is lumens and in the correct spectrum. Everything else is secondary. Keep your light between 6500-6700k with at least 20 lumens per liter for low light plants 30per for medium and above 30 for high light red plants. If the lumen requirements aren't met doesn't matter how much fertilizer or fancy substrates one has plants will struggle without proper light.
Oh yeah and CO2 without red plants is a waste of time and money
Sorry for the long winded rant
