First, mud and sand can raise grass, mud has fertility, can reduce ph, but there is a use period, it is not very convenient to turn over the tank, new mud algae, fertility control is more difficult than sand, mud can raise most of the high-grade aquatic plants, sand is limited in this regard, but for most novices, you will not rise to the difficulty of the aquatic weeds all at once; The advantages and disadvantages of sand are just the opposite, **cheap, but the sand should pay attention to the particle size and water solubility, the particle selection of 5-8mm size is symmetrical, basically suitable for most aquatic plants planting, the amount is spread to the bottom of the tank 5-7cm. Inspiration Fish.
Second, fertilizer fertilizer has root fertilizer, base fertilizer, liquid fertilizer and organic fertilizer, etc., it is not recommended to add base fertilizer in the new tank, even if the sand has no fertility, do not add, because poor treatment will lead to fertilizer water, resulting in algae, green water and so on. Do not add any fertilizer within 3 months of opening the new mud, and you can add some root fertilizer and liquid fertilizer one month after the opening of the sand cylinder.
3. Temperature Some aquatic plants are indeed afraid of heat, pay attention to the temperature of your fish tank when planting, such as snowflake grass, a very beautiful medium view grass, the water temperature will stop growing if the water temperature exceeds 28 degrees, and the leaves will melt and die if the water temperature exceeds 29 degrees, and the lilacs will melt the leaves if they exceed 30 degrees, and the dwarf pearls will grow slower than snails above 30 degrees, but they will not die, and the ones I have been exposed to seem to be nothing serious, anyway, now my water temperature is 30 degrees, and everything is normal with the creatures.
Fourth, calculate the water volume of your fish tank, buy a water pump with a nominal flow rate of 3-5 times the water volume of the fish tank to make a filtration system, it should be big but not small. It is possible to purchase one with an oil film processor.
