[CVtv] Episode 3 – Maxspect Gyre: Alternating Gyre Mode
Did you know you can run your Gyre in reverse mode?
O ne of the Gyres most unique features and which sets this pump apart from any other pump in the market is its ability to run in reverse mode. This is like having two pumps in one. Not only can you have your pump create it’s signature gyre as it runs, but you can actually have the pump switch to reverse mode and then create the gyre the in the opposite direction. There isn’t a pump out in the market capable of doing this by itself!
Running the Gyre in Alternate Mode allows our tank flow to more closely resemble that of nature. This creates an environment of happy fish and healthy growing corals without the need of having multiple power heads all running at the same time.
PREPARING THE GYRE
Before we start, we need a few things. We will need the spare propellers and directional cages that came with your gyre.
The alternating Gyre mode creates a tremendous amount of torque on the pump so if you have a tank with glass ticker than .5 inches, you will also need the additional magnet kit. This magnet kit can be purchased at www.coralvue.com.
INSTALLING THE PROPELLERS
The first step in setting up Alternating Gyre Mode is to install the correct propellers and directional cages.
By default, the gyre comes with propellers A and B installed.
If you play close attention to the propellers, you will notice that the blades are angled. When installed, both propellers A and B have all blades facing the same direction. This allows the entire length of the propeller to grab a large amounts of water and move it forward to create the linear flow and it’s trademark gyre.
By removing one of the propellers from the gyre and replacing it with one of the ones included in the box, we can now two propellers with blades angled in opposite direction. Your gyre will now be running on either two A propellers or two B propellers.
Because of the angle of the blades, now half of the gyre will be able to fully grab water and move it forward and the other half will create turbulence.
BUT, when the gyre runs in the opposite direction… yes, you guessed it!!!! The other propeller will now be able to fully grab water and move it and the propeller on the opposite end of the gyre will now just create turbulence.
Now you have a pump that can efficiently cycle water in both directions. You now have two pumps in one!
INSTALLING THE DIRECTIONAL CAGES
After configuring the propellers, we now need to install the directional cages.
Make sure that the cages match the propeller you are using. If you are using two A propellers, then you should be installing two A directional cages. If you are using two B propellers, make sure that you install two B directional cages.
PROGRAMMING THE GYRE
To program the gyre in Alternating mode, please check out Episode one: Gyre 101 where we show you a step-by-step programming guide for each of the gyre’s controllable modes.
INSTALLING THE GYRE
Once we have configured the pump, it is time to mount it in our aquarium.
There are many locations where the pump can be installed to run alternating gyre mode. You can run the pump horizontally at the top end of the tank, or you can run it vertically. You can run it vertically on the back end of the tank, or if you have a large enough tank with center overflow, you can mount it on the center overflow.
Before making the final decision as to where the pump will be mounted, we need to assess one very important part of our reef tank… the sandbed. Having a tank with sandbed or bare bottom will dictate the directional speed. If you have a sandbed, you will need to test the gyre at different speeds to make sure that you don’t end up with a sandstorm. If you have a bare bottom tank, then the sky is the limit!
When mounting the gyre, pay close attention to the directional cages. Make sure that the intake is rotated away from the aquarium glass or overflow to prevent restricting the intake of water.
One of the great things about the Alternating Gyre Mode is its ability to set different speeds for each of the gyre directions. You can adjust the speed of the gyre based on the distance the water needs to travel.
TROUBLESHOOTING ALTERNATE GYRE MODE
Here are some answers to frequently asked questions regarding the Alternating Gyre Mode.
How do I differentiate between propeller A and propeller B?
When looking at the propellers, if the blades are facing you and the white shaft attached to the propeller is on the left, then you are looking at Propeller A.
If the blades are facing you and the white shaft attached to the propeller is on the right, then you are holding Propeller B.
I am running my gyre in Alternating Gyre Mode but it does not move any water when running at 100% reverse. What’s going on?
Make sure that you have installed all propellers and cages of the same letter. Either a set of two A’s or a set of two B’s.
I am running my pump in alternating gyre mode and it keeps drawing air from the water surface. How do I fix it?
First, make sure that the pump is fully submerged. If you are running the pump horizontally, make sure that the water intake is not too close to the water surface when drawing water from the top. If you are running the gyre vertically, make sure that the water intake is not up against the panel but instead, facing away from it.
I am running the alternating gyre more and I am having a hard time keeping my sand in place. What now?
Reduce the speed of the gyre or move it to a different location. You can also try changing the direction of the cages.
