Underwater sandfall for waterfall not working

Dear community experts,

I am new to this forum joined today. Also brought aquarium 2 month before itís size 40*30*55 with 20 fishes.

Trying for underwater waterfall over already built rock structure like stairs brought from market.

Pump using 50w GH-111.

T pvc connector slit as well and connected to half cut coke bottle upside down on the top of T connector.. and finally pvc pipe extend till dropping water on the rock structure..

Water abl to reach at the top.. Issue facing is instead of sand going down towards the T connector hole under this half cut bottle itís blowing by air towards upwards.. So no sandfall at the end or very few sand coming out .. Pls suggest what could be possibly wrong here
