Lamp is just what I was expecting. Instructions was quick and easy. Be careful and use distilled water and add just the right amount of liquid dishwasher detergent soap. I accidently added a little too much of soap and in my tank it look like it was cloudy but it was just the soap mixed in with the water, it isn't too distracting but still noticeable when the lamp was on. I was concerned when first putting the jellyfish in the tank that the jellyfish would stay to the top of the tank but after ten minutes the jellyfish were moving everywhere in the tank. I used a chopstick to push the jellyfish down far into the tank so be sure to use something similar instead of using your hand, it's much easier. It's very cool and it looks just like real jellyfish. The only downside to this lamp is that it's a little pricey but still happy with my purchase. Would buy it again.
*UPDATE*
So after like a week, the soapy water that looked cloudy like I mentioned in my original post, has almost disappeared so the water is a lot clearer now and the jelly fish still move around nicely inside the tank! So it is not a need for concern if you accidentally add had a little too much soap.
