Review: 25W nano heater that will fit in a Fluval Edge HOB filter (4" long!)

[Kwen]

I've received and installed the 25w glass model, looks like they made it slimmer!
It looks like this now:


I cutted a hole (2x3) on the opposite side to get some more room, running with a sponge, 50ml bag of purigen (100ml split in 2), sponge standing up and bag of biomax placed in a 90deg shape (over the heater and on top of the 2nd sponge)

How are these heaters working out for you?

How do you reseal the purigen bag tightly enough to prevent little purigen pieces from floating off.

I use the Boyds Chemi Bag, works great for Purigen is far more flexible than the Seachem bags and can be sealed with a small zip-tie and used over and over again. Also can be cut to size to fit the smaller HOB filters.

Flat iron for straightening hair wrapped in foil, melts quite (too) quickly

Maybe a sewing machine will work?
I did that to seal a media bag I used for purigen.
It was too large so I had to cut it into 2 and resealed it back up.

After spending literally hours looking for the perfect heater for my Fluval Edge. I've bumped into this thread. Genius!

I know it's an old thread, but this has given time for the OP and other people to now have a definitive opinion on the mentioned Hong Kong compact heater, and the technique of mounting it within the HOB filter.

How are people getting on with this? Is it working out OK?

My tank has finally completed the nitrogen cycle and I'm dying to get stocking. But my heater isn't working now, so I need a replacement!

i WISH i saw this earlier... I'm subscribing...

as far as purgen goes I bought the 'bag' and used my surger to make smaller bags...

made 3 small bags for my azoo palm and one for my finnex p-360
plus leftover

(used 1 bag, and one container of purgen .. lots of purgen left)

Does anyone know where to source the up aqua mini heater? I can' t seem to find it on Ebay, or anywhere else for that matter.

The Archaea heater is very, very close to this size, and does not need a transformer.

Only negative is that the suction cups suck.

These 2 heaters are a bit flatter than normal and fit nicely into tight spaces. I have seen the second one but havent used it. The first on ( aqueon ) I use in my 2g spec. It keeps temp pretty warm ( sometimes too warm )

[Icarus5]

Thanks VJM. It looks like the Archaea heater is the only one that will fit in the HOB if I intend to do the same mod that Tuonor did. The Archaea is 1/2" longer than the one that Tuonor used...will it still work? Does anyone else have experience using the Archaea in this way?

Neither of those is adjustable, for those that that matters to. I was looking for a 25W adjustable like the OP.

Not everybody will care, though.
