Comments: The upgrade worked pretty well. The only problem that I had with it was that my fishes keep getting stuck in the filtration media basket. It seems like they would swim up the the basket to check it out then go down the basket and get stuck. I would have to keep helping out the fishes that got stuck in the basket. I wish there was some kind of screen to cover the top of the basket so that the fish won't go inside.

Comments: I have just installed the upgrade kit,will see in a few days how it works. I think it should have been included in the Red Sea prizm skimmer , when I think of the word skimmer it maked me think the surface is going to be skimmed not a few inches below it. Thank You

Comments: The skimmer is hard to adjust and the lever that allows movement broke off the first time i adjuster. It does what is suppose to but could be improved

Comments: I am very pleased with this product! The skimmer takes the muck right off the top of my water. The media basket is great for whatever you wish to put into it. I recommend this product for anyone who has a regular Prizm.

Comments: As soonas I installed it my water was instantly cleaned, I highly recommend this product.

Comments: Fits well and works as advertised.
<br />Still think it should come with the base product rather than being an upgrade.

Comments: It's totally worth the limited investment. It multiplies the effectiveness to that of a devise costing more than twice as much.

Comments: Very nice upgrade for money. Adjusting was hard at first. Once you adjust the water level, it works great. Media container stops microbubbles.

Comments: This upgrade kit is so bad to use.
<br />Difficult to regulate the position for skimming water surface. Even already regulated the position, it doesn't do skimming well.

Comments: I had a problem with surface scum and now I do not, love this product.
