/diy/ - Do It Yourself

>>1667201
I fell for the LED jew. The light is too weak and I don't want to spend a bunch of money after my last mistake. What can I do to light my tank on the cheap to grow plants? I bought a grow lamp on the cheap but it has a warning to not have it on in the same room without eye protection on, so I can't use it without blinding everyone and everything near it. Also, my tank is now open top after installing the LED light and the water evaporates like a motherfucker. Should I cut a glass top for it, or just deal with it by topping off every day? Also, how can I remove the calcium evaporation ring without harming my fish with vinegar or PH down? I used a scrubber but the calcium build up just laughed at me.
