Looking at my graph I seen two drops that happend in different times could this be my probe going bad. Check the pic out.

Also is 2 degree temp swings from night to day bad for sps corals ?

Mine always swings worse than that its not a big deal. The worse thing you can do is try to chase it.
You biggest swings will always be at night.

 

[Anthony35]

Let your corals speak to you if you do not see a problem than leave it alone.

Agreed with Anthony. Do not chase your ph. It will always drop at night due to photosynthesis. And 2 degrees isnt bad at all as long as it is gradual.

the temp swing can be a concern. Dont chase PH,just keep it from swinging more than a .3 or more daily. but looking at that graph, it seems like an abrupt change twice. could be a faulty probe or equipment.

Yeap that's what I'm thinking

Is the wire for the probe running near other wires?

Yes

Does this event coincide with any other events? I know my reefkeeper used to alarm for ph when the lights came on. Moving the probe away from lights solved it.

No I don't have anything that comes on and off around the sand time the only thing I can think of is my ato but it's not close to it. Here is a 7 day graph

What is your sample interval on this?

What you mean?

 

[pickupman66]

How often does your cknt% older take a sample reading from probe to make this graph?

Do not know but I look at the graph on the server and it does not show the drop so it my be an app error.
