Undergravel heaters?

Hey everyone.

Just a quick question, i've done a pretty extensive search of the forum but can't find any info.

Does anybody know about undergravel filters, are they a good idea and do they work better or worse than conventional ones?

I'm settin up a nano tank and an undergravel filter would be a great space saver, however i've never really seen them apart from a few online shops.

Heres the ebay site that i found it.

I don't have one, but have only heard about them. From what I have heard, they have a tendency to get clogged from the substrate and are a pain to clean because of their location.

Hey leifthebunny, cheers for gettin bak so quick.

Thats a very good point bout them cloggin up, they would be an complete nightmare to clean. Was kinda hoppin i could just bury it and forget bout it, but nothin's ever that simple wid aquariums.

I have heard of some using them but I would recommend against it unless you are willing to gte another filter and run your undergravel as a reverse flow filter. This will keep all the junk out of the filter plates and keep the heater from clogging. You will need to use larger gravel to make sure you have an even flow and so that the gunk is always suspended so it can be removed by your other filter. Not a good option but will allow for an undergavel filter and is the only way I would recommend using one.

yes, there rae those that use them in other ways but I have not seen any of them explain how they gravel vac nor get the gunk off the filter without moving it.
