Well stores are open now... you can just go to petco and buy their glass thermometer. I use those cheap little glass ones in QT tanks and they work fine. You won't be able to tell to a half a degree but you will know if your tank is 77 or 82.

I would recommend getting a cheap meat thermometer on Amazon. They tend to be fairly accurate (or at least consistent and reliable) and are useful for double checking stuff. I use it during quarantine to test temps because it's easy to sterilize a bare metal pen between uses.I'd also agree that the Apex probe is more likely to be the culprit than an actual high temp. When you see the temperature spike that badly that quickly, it's almost always down to one of two things: broken equipment, or broken temperature probe. You did your diligence with ruling out broken equipment, which means it's down to the probe. A replacement temperature probe is about $30-$40. It's not a bad idea to have a spare one on hand at all times - they're one of the most common points of failure on the Apex. I've had the exact same situation happen to me, except in my case it took me a while to figure out that the probe had gone bad, because it happened in the middle of a heat wave and we don't have central air, so the elevated temperature made sense if I didn't think about it too much.
LOL, my wife keeps my house at 68 degrees. It's freaking cold. My basement sump helps the tank keep cooler also.Yes I have central AC. I also considered turning it down. It's 74 at the moment. I have the tank lights off and the fans are on. Temp is still elevated. I thought this was a canopy traping heat issue. Now I am leaning to hot pumps. IDK.
Yep, @Jedi1199 mentioned doing this earlier. I realized that I did not have any ice in the house somehow the machine was off so I was literally waiting while I watched water freeze to do this test.Wouldn't it be better to calibrate to freezing with some ice water? That is closer in temp to what we are doing than boiling water. I mean it's not perfect but we don't need perfect here. We need "pretty close"

33 and 32.3
That's the exact one I use actually! Love it.Grey is the winner.
Why not use the inkbird as your secondary probe?Update time.
So I determined that the Apex temp probe was reading high by 4.1 degrees. Yes, that much. I could have adjusted it through the calibration function, but I felt better replacing it. New probe installed and an adjustment to my heater control programing and it looks like I am back in business.
I have my inkbird set to 77 degrees and I am maintaining very close to that now. Here is the graph since the new probe install.
I now have plans to implement an secondary temp probe and set up alerts if there is a deviation of let's say 0.2 degrees +or- between the two probes which should alert me to any drift over time.
Well basically lack of trust. Fool me once shame on you, fool me twice shame on me. The inkbird is still indicating the correct temp and has not drifted over time. I am not sure when or what caused the Apex to drift, but it did. Either way I now have alarms set up so if either get out of range I will know much sooner. When I add a redundant Apex probe this should be even better.Why not use the inkbird as your secondary probe?
I was getting nervous because I didn't want to cross 83. I am glad that I looked into this now before the real summer heat hit.I pop 81 every day. Home ac at 77.
They all seem happy.
83 is pushing it from what I have read. A fan in the sump drawing air out and a fan across the top of the tank can help.I was getting nervous because I didn't want to cross 83. I am glad that I looked into this now before the real summer heat hit.
Exactly, which was my concern. My post today was an update on all being well and running 77ish as well as some changes I made to prevent this in the future.83 is pushing it from what I have read. A fan in the sump drawing air out and a fan across the top of the tank can help.
Like the one I have on my freshwater tank? LOLI long for the day when you can just put a sticker on your tank and know the temperature.
I have heard that as well. The theory being that higher temps promote a higher metabolism and thus higher growth. But I do not want to find the limit.My in-house RSM250 suffers from overheating, like all these units, and ran at 28-29C last summer before I finally acquired some water-cooling fans. I only keep softies in that tank, and didn't really notice any adverse effects at all. The xenia and leathers actually seem to prefer higher temperatures.
Did you just drop the fresh word?Like the one I have on my freshwater tank? LOL
Yes I did and I'm proud and loud to say it!! LOLDid you just drop the fresh word?
We will always have Bali... Good timesYes I did and I'm proud and loud to say it!! LOL
