Tetra HT10 Heater Review - 100 watt Disaster

The Tetra Heater ht10 50 watt review. These heaters are completely junk. I highly advise buying the eheim jager Heater. They’ve been top rated for a couple years now.

Fish aquarium after thoughts:
I’ve left my male koi Nemo and female koi together after they bred. I also added some White Cloud Mountain minnows. Didn’t plan on keeping the young. They didn’t get along for a week or so, but nothing violent. Just a little chasing. Now here we are they are happy together, with plenty of hiding spaces, in a 10 gallon. All aggression is gone. I would not try and replicate my success only because you will most likely end up with a not so kind fish and they won’t get along.

Heck, I had 6 females in a 40 gallon without a male. One of the females was a jerk (the prettiest one, of course), and she was trying to kill off the the others one at a time. I had to take her out and set her up on her own. It’s been my experience that some people can have tanks like yours, where everyone is coexisting, but it’s all very dependent on the personality of the individual bettas.

I absolutely agree with you.
I've also had several different mbuna cichlids in a different tank together and had most of them raise fry. the demasoni didn't even kill anyone. Key I found is if you change your tank setup and decor enough by moving things around, they will be less territorial that way. Just some of my experiences anyway.

I’ve definitely tried that before, and recommend it to my customers when they come in with territorial issues. But my little half moon female was just like a stone cold killer lmao. I have 1 male and one 1 female in a moderately planted 55 gal tank with lots of other community fish and they have been no trouble at all, they haven't tried to breed and generally they stay away from each other unless its feeding time.

On the flip side the female I have was in a 30 gal with another male and he beat her up pretty good. I feel it can be done with no stress or harm to them if you consider a few things. 1. Personality of the two fish. One might just be a dick like my last male. 2. Tank size and places to hide I.e. wood, plants decor ecr. 3. Distractions within the tank. Other fish are good at stealing the attention of aggressive fish. Like if there is a fish bullying another and a group of fast moving fish swim between them, it will inherently draw the aggressors attention.

4. Are you willing to separate pr rehom if it doesnt work, no sense letting a fish get beat up. If you notice aggression then you must have a plan to separate, and dont try again with the same two betta. I separated mine. unfortunately the male got an infection and died and I purchased another male. Luckily the one I got is a over dramatic sloth of a betta and doesnt give two craps about the female.

Biologically they can inhabit the same tank,, but personality and the conditions you present them will ultimately decide whether you can or cant. Hope that helps.

I'm laughing with you about your current male betta. Mine is so chill that he is currently cuddling with the newborn molly babies in the tank. He lies in his water wisteria or on a leaf and then goes does an exploratory lap and then another 2 hour nap.

I agree, all of these things depend first and foremost on the personality of the fish. Always know what your backup plan is if fish aren't getting along. Space is a huge key after personality.

If you do try this maybe try more then 100gs and 5 females at least. The females may nip his fins so if that's a consern maybe try finding a plaket male. Also watch the individual fish's personality. This is the biggest thing. If he flares at other fish while in the cup he's going to chase them in the tank. It's just like watching the male to see if he can go in with other tank mates. If you're not sure how he's going to be then maybe try a test run with three guppies for at least week. Im not saying I condone everyone doing it but im also not a hypocrite because I've done it before, if you pay attention and take the time you're chances go from 0% to 45%-75% but even if he's fine now doesn't mean hes always going to be.

Thanks for telling me instead of instantly jumping because thats all the experience I've had commenting in the group recently but bettas are my favorite and tried. I just didn't proof read as well as I thought. yeah I feel the group is or should be about sharing knowledge and experiences but when someone is misinformed they instantly get bashed for being an expert yet. I started keeping fish 4 years ago and I learn new things every day.

I had a male in with my sorority of 12 in my 55 gallon. Of course it wasnt his perm home as I just hadnt had a tank at the time, but he was in there for a few weeks. He got beat down. Bad. Personal experience, I wouldnt unless breeding.

You are so correct about it not keeping right temperature. I decided to get back in into aquarium and my son gave me this heater and i quickly noticed it not accurate.

[savagefurry]

I have two of these types of heaters, each in a 10 gallon tank, have had them going on a year now with no issues at all so far. But only time will tell. If anything happens, I'll return with an update lol.

[jimmysides]

My wife decided she wanted an aquarium. Being the "good" husband I have been diligently researching. I (against my better judgement) bought her a Glofish brand tank tonight. We brought it home and set it up to start cycling it. This kit came with the heater mentioned in this review. We got it all set up and I was pleased to see her reaction. That is until I heater isn't working. We bought it tonight and fresh out of the box it's defective. Looks like I'll be back at the pet store tomorrow for a BETTER heater.

[mellyssa]

I’m having the same problem, I got that heater for my 20g tank because it advertised that can be use in 10-30 gallon tanks and is keeping the water between 72f instead of 78f, so frustrating.

[leflopjames]

Did this guy just confess to killing fish?

[Matthew.E.Kelly.]

I didn't know Betta Fish Keepers was your group, man, that's awesome. I post and comment there all the time.

Yeah, this heater is useless.

I always tell people with small aquariums to get the Uniclife 25 watt adjustable, it's the same size as the HT-10 and you can set the temp. It works much better than any other heater of the same size, and it's around $12 on Amazon usually.

EDIT - I've never had a terrible experience with the HT-10 but I did stop using it on a 3.5g betta tank in 2016 when it literally stopped heating the water. The light came on and said it was heating but the actual water temp was ambient room temp, which was definitely NOT good for the betta who was in there because the room was about 68 degrees.

On a brighter note I got him a better heater that day and slowly raised temps, he's been happy (in a 5g tank) ever since. Kept at 79 degrees. I have about 30 other bettas as well.

[rantsandreviews]

Sadly most heaters...even really expensive heaters...are generally only able to RELIABLY raise aquarium temps 3 to 6 degrees above ambient. Serious hobbyists use heater controllers for the best results. I agree with your assessment on the HT10 but I would also add that any non adjustable heater is junk.

[rancherome]

Seems my light keeps going off after about 5mns and I just set the tank up. Is that normal the light keeps going off. I unplug and plug back in after 5 mns it goes off

[seaturtledog]

I just bought the HT 30 and it seemed to be working fine until i noticed the temp was at 90 in my new planted tank with no fish. I pulled it out and it had a covering of rust so it was leaking. If I had fish they would of been cooked. It did work for a couple of weeks but i suspect it had a crack from shipping. I do not like the idea of no temp control and for plants I might want it a bit cooler.

[SkilledCoconut]

These are advertised with a electronic thermostat, but you said they don't have a thermostat. I'm confused

[Revmcoon]

I just picked some of these 100 watt up for dirt cheap on a sale mainly for backup heaters not main heaters if I need a heater for every day I’d go for anything else

[steventaylor]

Completely disagree, recently needed a heater for a 5.5 gal tank. Bought the 100 Watt model, actually on sale at PetSmart for 9.99$ and it works great, built in thermostat ( yes it has a thermostat ) keeps water consistently 78.1 to 78.3 F
Highly recommend it to anyone.
If you want, go ahead and spend alot more. But not at all necessary. And if for some reason . It doesn't work as advertised. Return it for one that does. Everything is made in Asia somewhere and quality control can be a little lacking.

[josemontalvo]

Thank you for the heads up on the piece of junk. I’ve lost fish to water heaters that would never turn off. Tetra company, Please Pat attention to your base product consumers!

[MissMichSan]

Better make sure to get a thermostat or one with a thermostat my beta was freezing because I had my AC on so it seems it stays at room temp.

[FlyoverMeTez]

I got 3 brand new ones I kept returning to the store. 2 didnt ever light up red. And third one never heat up.

[GiovanniJC]

i bought the 30-40 version and it hasn't worked at all i dont know what to do i checked the water temp it was heated and now after it heated once it turned off

[JustMyFish]

A good small heater is the Zoopet 30w It's great for fry tanks so should be good for a Betta tank. It's only £8.00. Not a big brand but very reliable had one for 2 years now no problems.

[Dr.M.Stephen.P.]

this heater works, if fish needs more heat it, fish goes near to the heater, temperature stays at 25 degrees celcius (-+ 1 degree celcius)
can be used for 99% fish, including gold fish as 25 degrees celcius is luke warm hot temperature for fish

[Tox]

I've got the 50 watt version in a 3 gallon betta tank with a thermostat tape on the side that reads 78 degrees consistently.

[TheNinfadance]

This is really true, for good fish keepers this heater is useless!!
