Making sure Neptune Apex code is correct for Alk

chris31759 · Jan 31, 2016

If anyone wants to help me verify my Apex code is correct for my BRS 1.1ml dosing pump, I would appreciate it. I will run it tonight hooked up to a light just to verify but I might miss a few doses do to sleeping. I think it will dose 3.3 ml every hour for 6 hours. I am not sure were to put the ph fail safe command. Does it go at the beginning or the end. I thought the beginning otherwise the other commands would be conducted with out shutting off. I know the ph fail safe is low. It's winter here and we are all closed up. So ph never gets above 8.2 right now. I ordered 1/2" murlock pipe to run from the skimmer through the crawl space to a small vent on the side of the house. That will be a project for next weekend. Thanks for you help.

Fallback OFF
Set OFF
If pH > 8.30 Then OFF
If Time 21:00 to 21:03 Then ON
If Time 22:00 to 22:03 Then ON
If Time 23:00 to 23:03 Then ON
If Time 00:00 to 00:03 Then ON
If Time 01:00 to 01:03 Then ON
If Time 02:00 to 02:03 Then ON
If Time 03:00 to 03:03 Then ON
If FeedA 000 Then OFF

Or you could use

OSC 000:00/003:00/057:00 Then ON
If time 03:30 to 20:30 Then OFF

This is a much better code.

It looks like you should be fine either way.

Be sure to calibrate your BRS dosers; don't just assume they dose 1.1ml per minute. I believe the ph command should be last. Be sure and read the complete apex manual online, there is a section on the importance of order.

Thank you for the replies. Trido the code you provided looks much cleaner. I will make sure to calibrate pumps before connecting them. I am currently using a Bubble Magnus doser that I plan on moving to the frag tank.
