Planted Nano Filters

[GUB]

I have an arcadia 35L nano which I have planted up, got some extra light in, and will shortly be looking at adding CO2 to. I also have a small group of rasbora in there which are great. I am just concerned that the filter is 1. a tiny bit unsightly in such a small tank, and 2. Maybe not up to the job as it seems caked in muck after a v short time. I have seen people talking about HOB filters, which my LFS seem to have in stock (Boyu and this one) .

My question is, what sort of lph should I look for on one of these things and will I be losing valuable CO2 from the 'waterfall' effect of these filters (I would be using a yeast based CO2 rather than injection).

If a HOB is out of the question, can anyone recommend an external that doesnt cost the earth but is up to the job!

350l/ph aim for. you will have to position the outlet to creat as little surface agitation as possible. Or go for the EDEN 501 http/www.aquaessentials.co.uk/index.php?...roducts_id=1505

Let me add, you can never over filter, this in mind the best 3 filters would be the eden 501 hydor prime 10 and the fluval 105 (not sure if that's the name, smallest one).

I've got a Eden for sale in the sale section.
