That is a very good question. Currently I only calibrate once a year and I use a laser temp gun pointed at the substrate along with an old school floating thermometer. I trust both devices, so take an average reading. I also check against my Hanna digital SG probe, when measuring specific gravity once a week. You know, now that you mention it, calibrating for temp is pretty tricky to do right. How have you been doing it?
Upgraded to the Innovative Marine Helio dual element system. I am very pleased with this product. A bit pricey but well made and very stable.
Nice. I’ll have to check that one out too.
Where in New England do you live? I’m just outside of Worcester Ma.. Do you sell frags?
Hudson Valley region. Sometimes. Just depends on what I have available
@@craftaquatic6472 that’s not too far from me. Once I’m ready, I’ll give you a shout. Putting together a 125 build currently
What kind of substrate did you use in your 120? Very curious on testing a larger grade substrate!
It is 50lb course coral rubble, purchased in bulk from a local shop. It has worked really well in our high flow reef.
What do you use and trust to calibrate any verify true temp in your reef?
