CAD Lights PLS-50 Elite Nano Pipeless Protein skimmer Information

Product Manuals & Documentation

The PLS-50 Elite from CAD Lights (Works for All-In-One filters, sumps or directly In-Tank).

Welcome to the cutting edge of protein skimming! Building on the incredible success of the original PLS-50, CAD Lights set forth to refine and re-imagine every last detail to create the ultimate nano reef protein skimmer. The original PLS-50 started by combining features previously only seen in full sized skimmers meant for large aquariums, integrating a bubble plate, air injection venturi, 2-way air silencer, 100% cell cast acrylic construction, a true pin-wheel impeller, and of course our ultra space saving patented pipeless designed controls. Building upon this breakthrough design, CAD Lights pushed the limits to refine every last detail and create the pinnacle of nano reef protein skimming: The PLS-50 Elite.

PLS-50 Elite Nano Protein Skimmer Specifications:
- Dimensions: 3.25 x 3.25" x 15"

Effective but Touchy

Comments: After break-in, the PLS-50 Elite has performed very well although dialing it in (and keeping it dialed in) is VERY tricky. Place it where the water level is constant and make sure to use a ruler to measure the depth to the pump intake. Skimmate produced is a bit more watery than I've seen from other skimmers but has done a good job removing particulates and organics from my JBJ 30RL.

Still Breaking in?

Comments: Well, I've had this unit running 24/7 for about 3 weeks now; the 'micro' bubbles have definitely gotten smaller; not overwhelming the tank (45Gal JBJ Rimless). I am hoping that as the unit continues to break in; & it will ultimately stop spewing bubbles into the display tank. I've tried to add some filter/sponge material into the back chamber to reduce the bubbles, yet that's not working all to well. I will give this unit another 3-4 weeks; Tank will have cycled by then and I'll be ready to add livestock. If I cannot get it to stop sending bubbles into the tank via the returns - I'll be looking for another slim unit to fit my system. Seems to be skimming well; does take/need adjusting - so you need to be on top of the unit; this too may break in after some additional time. Good Luck. Love MarineDepot!

Great little skimmer

Comments: I bought this for my Innovative Marine Micro 30L tank and it fits perfect. So far it works well. The adjustment is a bit on the sensitive side but once set you can leave it alone. One thing I could suggest to the manufacture and frankly to all manufactures of marine products. Is it would not hurt to give people some instructions and suggestions for use. It will not hurt peoples intelligence if they didn't have to guess on assembly and placement and adjustments. Not everyone wants to find there information on Youtube! This skimmer literally comes with nothing not even a parts list. Aside from that the skimmer itself works great.

Comments: This skimmer is difficult to adjust. If you are keeping it in the back of a dark sump, I would not recommend it for this reason. I found that after rotating the skimmer for adjustment that when the set screw is tightened, the adjustment was thrown off and it would overflow. I believe that it should not be used in an aquarium over 30 total gallons as the rating up to 60 gallons in my opinion is way too generous. I placed a hugh amount of skimmate from my 180 gallon tank in the tank with this skimmer and in no way, did I obtain anywhere near the skimmate I had put in the tank. I know that this is subjective but that is my opinion. It can be hung on smaller tanks with a rim. Mine is on a 20 gallon long. It will need a block of some sort to stay straight up. I used a pair of magnets for this purpose.

Comments: The skimmer itself is very nice and very small. The CAD Lights company is garbage. Waited two weeks for a replacement part for this BRAND NEW skimmer. Store ended up having to replace my entire new skimmer due to CAD Lights never sending me a part or returning phone calls to the store.

Comments: I bought this to replace my Innovative Marine Skimmer, which was a complete nightmare. I was pleased to find that the CAD Lights PLS-50 Elite delivered. Very quite. Easy to set up. Very few micro bubbles. Started producing results within 36 hours. If you are looking for a good skimmer to fit your Innovative Marine Nuvo 40, this is it. I would give it a 5 stars if the air adjustment was less sensitive.

Comments: I take one star because I just can't get a dry foam out of it. It does remove pollutants, just wet. Generally have to empty cup out twice a week so it doesn't overflow. Easy to set up and obviously well made. Does a nice job on my 29 gallon nano w/10 gallon sump.
