Hi,

I have just got a seneye home aquarium monitor off a friend for free, it seems to be working well, the results are matching my liquid tests.

but the light monitor is not working because i need to get something to make it float, seneye have this product:

but for $35 Australian there has to be something cheaper alternative!!

Does anyone have a good idea?

Thanks
