Heater Suction Cups - Advice

I've been having issues getting the suction cups to stay stuck to the glass. They are for my 150W Heater. I decided to give up on them and ordered magnetic holders online.

I haven't received them yet but was wondering if anyone here has tried them. I'm mostly worried about the magnets corrupting the heater in some way- I don't want to wake up to boiled fish.

Have you tried to contact the manufacturer? The ones you have might be defectives and they might have replacement ones. Mind you, my heater is small and the cups are not giving me any problems.

They worked for me for about a year, and it looks like the heater is out of warranty now. I just don't want to have to keep replacing the suction cups - the magnetic ones are only a little bit more than the replacement cups.

I'll receive the magnetic ones in the mail tomorrow (hopefully) and as long as the packaging doesn't have any warnings not to use it with certain heaters, I'll give it a try and just keep a very close eye on the temp.

They sell replacment one at your LFS's.
I have hade the same Problem, I put new ones on and they work.
After a year the water takes a toll on them. They would need Changed every so often.

I dont know if i would put anything metal in my tank. The metal could leach into your tank then hurt your fish and cause other problems.

Maybe Byron will see this and be able to give a better imput on it. He knows a little more than i do. lol Alot more.

Subject: Larry LaPrise dead at 93

With all the sadness and trauma going on in the world at the moment, it is worth reflecting on the death of a very important person, which almost went unnoticed last week.

Larry LaPrise, the man that wrote "The Hokey Pokey" died peacefully at the age of 93. The most traumatic part for his family was getting him into the coffin. They put his left leg in. And then the trouble started.

I have filters that have been in the tanks for more than 12 years and the plastic suction cups still hold the tubes in place. But I also have some that don't, only a few. I bought replacements. I guess like most things, there are some not as well-made as others and they bend and the suction no longer holds.

I've never seen the magnetic holders. Someone mentioned metal in the water, that is a concern and I personally would never put metal objects in the water. Acidic water corrodes most metals over time, some metals are highly toxic (like lead, copper, iron...). As for the magnetic field interfering with the heater, that is a very good question and I don't know the answer.

I don't know, I've never seen them. I would also be wondering if a magnetic field would somehow interfere with the heater? Cause it to stick on or off?

Once you will receive the magnets, you will see, they might be in a plastic casing. Personally i have not seen any, but i do not think they would affect the heater if they are made for this purpose.
