Ok. A plan is forming.
After looking for filters on-line and finding nothing very good commercially available, like only a single Fluval for ordering I ended up looking at home made designs and finding things suitable for either:
- Small tanks - foam in a canister and airpump. 5-10 gal.
- Large tanks - Foam, uplift tube and powerhead. x-x gal.
I've just figured out how I'm going to filter it. I've used my own design but it is a combination of the foam in a canister and the foam attached to a powerhead. I've attached an image.
Basically it is the top part of an internal power filter with the bottom cut down pushed into a food grade plastic tub which I've put a layer of ceramic media into. Then the rest has been topped up with more media and finally a deeper gravel layer. The output has had a piece of plastic tubing attached to deflect the outflow and give surface agitation.
I've tested it and it works. The flow rate is still fairly hardcore as it is a 400lph power head but then within the tank I believe it will be impossible to suck up and dice fry.
Next I'm going to get a plastic exercise matt and I've got some wood to cut to prepare a base for the tank. I am going to put it on the bottom level of a two tier metal tank stand I've got. I was going to put it somewhere awesome in the lounge which I've got earmarked for a shrimp/planted tank but the gap turned out to be a couple of inches short. Oh well! I'm also going to have to look at the electrics in that area because two tanks and two plugs mean I should actually get around to doing a wall mounted multiplug thing with breakers.
