Added a Neptune Apex WXM and VDM Module... I needed the VDM because I am at 5 Channels on my LED's. But it was cheap enough so not a big deal. I love the WXM Some folks say it is a huge waste because all it does is sets the mode of your Ecosmart pumps (Vortech MP10,40 and 60's). But it does a bit more.
First the MP10 has an issue with the long pulse mode. Weather that issue is I am an idiot and cant figure it out, or it is just too complicated, I can not get any of my pumps to do a 5 second pulse. Well with the WXM it is a few clicks of the mouse, tell it at what percentage and time of day and you are good to go.
The best feature with the WXM is you can change modes at different times of days. I personally hate most of the ecotech modes, but with this flexibility I can get it a little closer to reality. many people like the wave motion but I spend a lot of time on the ocean and I can say most waves have a period of about 5-7 seconds. Not 1 second. So I set mine for an antisync 5 second pulse most of the day, an short pulse at a lower power in the early morning and late afternoon, and a gently low power reefcrest mode at night.
After about 3 days of this my Alk and calc dropped drastically. It took me a couple of weeks to get it right but I am now dosing twice as much every day to maintain 8-9 DKH. Growth is much more noticeable. So my corals must love it as well.
The only thing I wish the WXM did was not just simply set the mode and power but rather have direct control over the power head so you can ramp up and down into a pulse at a custom rate. I am sure it is more a function of the MP10 and not the WXM that would allow this, but I think you can really create a lifelike rhythm...
