Is Finnex false advertising

[HBtank]

Yes, I run 78 in my reef and 85 in the Discus tank, should have clarified.

I received a response from Finnex and I don't really find it acceptable since we are not getting what we pay for. Even though they may keep my tank at the right temperature, I'm still not OK with it.



Hi Tim,

Thank you for contacting us with your concern. The TH-500s will be running at ±10%. If you are running 2X TH-500S heaters on a power strip, your Kill-A-Watt should read ±900W.

That is gibberish, not even technically accurate. Basically admitting they are closer to 450w heaters, and are actually 450 +-10%. You don’t drop 10% when doubling and still keep the variance, and pretending it could be up 550 (+10%) is cute.

This is what I received from Jehmco today

We have tested our titanium and found that they test higher than labelled.
500 watt tests ~ 640 watts
800 watts tests ~1000 watts
1000 watt tests ~ 1220 watts
1500 watts tests ~1800 watts

Thank you for your inquiry.

What would you recommend over them.... I'd rather stay no thermostat, but will go with something better if necessary. Preferably higher wattage.

Not trying to change topics, but why is 85 too hot for a reef tank? I dive all over the world and look at the temperatures. Virtually every reef I dive is between 82-86 degrees at ~50' down.

Dissolved oxygen goes down as temp goes up.

I have a nice Eheim heater that I use to heat my new SW it works great, never shuts off. Always on. PS I love eheim I have tubing that is over 30 years old.

Right, but if the Raja Ampat reefs, which many of our corals & fish originated from, is 86 degrees even down to 50-60', why do so many people say its bad/dangerous to have our tank in the 82-86 range? Is it because we don't have the ability to oxygenate our tanks as much as the ocean? Or maybe the flow of the ocean water is constantly bringing new oxygenated water in with the tides/upswells etc? I've always wondered why we keep our reefs so much colder than the actual reefs we are mimicking. Thanks for the info!

Really no, it won't hurt a thing. As mentioned before it's a little tougher to maintain o2 levels at higher temperatures, as well as some other variables such as refractometer readings and calibrations and other things that are temperature dependent.

I should have clarified when I said it's "œtoo hot".

It's not necessarily too hot for the animals, it just logistically and technically overcomplicates things for no reason when you can run a successful reef at much lower temperatures and save yourself a lot of headache and wattage.

Thanks. I've been keeping my tanks at 79 +/- 1 degree since I first entered this hobby 20 years ago and never really thought about the "why" beyond its what everyone does.

Basically yes, the gallons per fish in the ocean compared to our tanks is a scale of magnitudes I don't want to try and wrap my brain around.
