well red plants are plants that have red leaves like tiger lily's and red cabomba they need more light to stay healthy and red and more light means more nutrients and more co2 to balance it out.get that wrong and you have a massive algae problem.so to keep things easy stay away from those plants.they will die out in the tank if you don't have the right conditions.
as for the carpet type type.it could be glosso, riccia,callitriche or japanese dwarf hairgrass but they need good lighting to stay low and spread out.
for tall plants things like green cabomba, eloda densa,japanese chress,vallisneria are easy going just don't plant them too near one another.
for rooted middle plants java fern,annubias,amazon sword ( theres giant and dwarf ),indian fern they all grow easily under the right circumstances.
as for moss java moss is the easiest they only need a piece of drift wood to be tied too and low lighting.that means a little shady area is ok for them but not too dark.tie them sparsely on the piece of wood coz ones that are bunched up and some parts that don't get light will die off
as for cleaning a good canister will force the dirt under the gravel thus changing it into plant food esp for the rooted plants.every time you do a wc don't mess up the gravel just suck up they debris on the very top of the gravel.try to get some Malaysian trumpet snails they help out a lot in aeration your tank gravel so there's no build up of toxic gasses and such down there.
plants are the first things to go in when you set up the tank.no fish allowed just yet. let the plant roots grow and settle in.the plants will help with the cycling.some fishes might knock them over or pull them out , plus at the start of a cycle it's not advisable to have fish in the tank.so it's best to leave the tank fishless first.
plants them when the tank is half full.only after finishing planting do you fill it up to the top
keep tabs of the water parameters you will see high ammonia in the first 2 weeks cloudy water could form even though you cleaned the gravel and made sure the water was clear at the start .do wc 20% or more every 1 or 2 days if it's cloudy.use a spray bar if you don't want to disturb or up root the plants.never let the plants dry out in the tank.that's very bad for them.
second week you will see a lower ammonia.nitrite will show up on your tests now wait for it to spike then it will go down to 0 in about 2 weeks or less coz of the plants. nitrate readings will be common in the tank coz ammonia gets turned into nitrite, nitrite turns into nitrate ( bacteria in the tank does this ) when you get 0 ammonia, 0 nitrite around 10 nitate your tank is fully cycled
pass the second week you could add a small fish or 2. just don't add too many too soon coz the tank will get very ugly very fast.cloudy and algae water will show up.the plants and fish might all die
during cycling in the first 3 weeks don't give your tank too much lighting as well.the plants haven't settled well in the tank yet so there's a lot of nutrients floating around you could get algae or bacterial blooms.if you see green stuff on the walls it means too much light cut light hours down a little.wc also help.maximum should be 8 hours a day not more and not less the 5.
