Underlying causes ?

So I have attached some pictures of my 2ft. I have a feeling it could be the flow rate, lack of circulation but I am using jebao with 750l/h !

please post your detail setup such as, substrate, light wattage and duration, CO2 level, etc.

Light is 40W water volume about 50l, co2 at 2bps. Light is on for 6 hours.
Soil : GEX (green packet)
Water change every 3 days - 20%

Sorry but with regards to flowrate, can i ask if the majority uses the rainbar that Eheim Canister provides? Its seems that the droplets of water doesn't do much to encourage flow of water in the tank. Would it be alright if u use the elbow bar on its own??
