Flow Restrictor 75-100 GPD Information

Ensure that your usual operations when it comes to maintaining a clean tank are going smoothly by being prepared with the Flow Restrictor from Pet Store. This is actually a replacement component, which serves as a sort of overflow strainer. It will come very useful when you've run out of pipes and cylinders, which are required when refilling your tanks. These tubes are also helpful when you need an extra pair of cords, which will allow your filtration gadgets to access the deepest levels of your case easier. This is an ideal component to have around, especially if you have powerheads, wave makers, and pumps set up.

As its name says, this gadget literally restricts the overly strong flow of the water, which may be caused by a clumsy refilling method, or the excess operations of your pumps. What this device does is that it keeps the circulation at an equilibrium, which will assure you that your protein skimmers and refugium are getting a steady stream of water to be filtered. The subtle waves will also prevent your fishes from becoming stressed when they feel the aggressive movements and impacts of the water around them. It maintains a normal rate of 75 to 100 GPD for your convenience.

You can be sure that the waves and bubbles that are being produced by your pumps are not disturbing the activities of your fish, as well as not letting the liquid pour out of the tank, by simply installing the Flow Restrictor.

Flow restrictor for 75–100 GPD membranes—for replacement or when upgrading to a higher GPD membrane.

Please note that these replacement cartridges are interchangeable with Captive Purity`s, Kent Marine`s, and SpectraPure`s RO or RO/DI units. We have researched the best replacement cartridges among these three manufacturers and offer only the best of each below.

**Variations of this product can be found in many online stores. The version we carry is of the highest quality. Although this item is eligible for price matching under our Low Price Guarantee, please be certain the product you want to price match is the same make and model.

Comments: They seem to do their job well. I purchased the 75 gpd for maintenance use on my Captive Purity and I have noticed any change for ratio of production to waste water.

Comments: I thought there would be some wiggle room for adjustment but the 60gpd restrictor came with a very short tubing length. Now my waste ratio is more than 6 to 1 - not good. Can't add length to this to adjust so I'll have to call it a loss and put my 40gpd restrictor back on and cut a little more off that tubing length. FYI - System installed is 60gpd Spectrapure ro/di 4 stage with booster pump (70psi)

75-100 GPD flow restrictor

Experience Level: Beginner

Comments: If your pressure is not at the high end this product may not work for you on the Spectra-Pure units. My pressure is at about 50psi, and the ratio out of the box is about 5-1 (Five waste to one pure). Part of this may be due to the fact that it is winter, and my water is a bit on the cooler side. If the tube were longer the ratio could be adjusted. I will try one with a longer tube and see if I can use this during the summer months.

Comments: This Flow Restrictor installed with ease and gave me the 4 to 1 ration i was looking for without having to cut it. I had bought a in-line restrictor and i wasn't working for me. I have the 75 gallon per day setup great buy!
