Unit Prices and Shipping

The following prices are my former “introductory” prices – I made a decision to keep them at this price, rather than raise them slightly.

However, as of February 1st 2018, I have had to bump up shipping prices slightly ($5) due to an increase in shipping rates.

L2 Retail Price:$399
*Shipping: $25 (US lower 48 only)

L4 Retail Price:$549
*Shipping: $35 (US lower 48 only)

L8 Retail Price:$849
*Shipping: $45 (US lower 48 only)

L16 Retail Price:$1349
*Shipping: $60 (US lower 48 only)

Shipping is calculated on a case by case basis outside the CONUS (US lower 48).

For a general estimate on international shipping:

  • Add $40 for shipping to Alaska or Hawaii
  • Add $50 for shipping to Canada
  • Add $80 for shipping to the UK, EU, Central America, South America, Singapore, Russia, etc
  • Add $100 for shipping to Australia or the Middle East

Pump Recommendations and Pricing

Flow recommendations are as follows.  Note that these figured reflect the actual flow delivered to the screen after all head losses.

For the L2, you want 210 GPH +/- 20 GPH, roughly.  You can go as high as 300 GPH.
For the L4 and larger, you want 420 GPH +/- 30 GPH, roughly.  You can go as high as 600 GPH.

Initially, a lower flow rate will help to keep the unit quiet and keep flow even across the screen.  As the screen matures, you can increase the flow if needed.  Therefore, you have quite a range of pumps that will work.

If you are looking for the pump that best fits your setup and preferences, start by finding a head-loss chart.  Calculate the vertical head (distance from the top of the water in which the pump is operating to the centerline of the slot pipe) and then add 24″.  24″ represents a rough approximation head-loss associated with the slot pipe and any elbows and plumbing parts along the way.  Locate the point on the curve that represents this head level to determine if the pump you are considering will meet your needs.

I provide a Two Little Fishies 3/4″ Ball Valve with every scrubber so that you may dial back the flow if needed.

I stock Rio Plus UL pumps.  Their head loss chart is located on the Specification tab on their website

In general, here are my recommendations:

L2 with standard vertical head (say, ~12″): Rio 1100
L2 with high vertical head (24″ vertical): Rio 1400

L4 with standard vertical head (also ~12″): Rio 1700
L4 with high vertical head: Rio 2100

L8 with standard vertical head (~16″): Rio 2100
L8 with high vertical head: Rio 2500

L16 with standard vertical head (~24″): Rio 2100 or 2500
L16 with high vertical head: Rio 2500
L16 with very high vertical head: Rio 3100

Pump Pricing: valid only for pumps purchased with scrubber

Rio 1100: $ 30
Rio 1400: $ 35
Rio 1700: $ 45
Rio 2100: $ 52
Rio 2500: $ 60
Rio 3100: $ 73

    Looking at the L4 for a heavily stocked 130 gallon system. Also have an oversized skimmer. Would the L4 still be the best option? Also what are the dimensions so I can see if it will fit in my sump.
