covered the tank

This part was really hard to accomplish, even more than anyone could think of. Because of problems with transport, getting the curtain later than expected and other factors, it took time to get the curtain/fabric to school. However finally, I was able to bring it, cover the tank and hopefully solve the algae issue. it is not professional but it covers the sun so that the algae doesn't grow in the tank. the system is still running and the tank is full of water and hydroponic solution. hopefully, everything works as planned.
