Sorry for continually bringing this back up.
Anyways I've been looking at filters some more. At our LFS they had the filters I'd been looking at set up. The poor fish were being brown around everywhere, in one tank the actual decoration had been lifted by the current and was stuck on the side of the tank. The tanks were small 6l tanks like mine. Anyways i didnt like the idea of what that would do to my plants.
So I did some digging in our fish draw at home, and I dug up an old air pump rated for 150l an hour (I highly doubt it but if it does half that I'm happy). Anyway I was thinking of buying a sponge filter casing, packing it with bioballs and filter fibre and using that instead. It works out way cheaper as well, which the miser in me likes LOL. So I think I'll order the sponge filter, if it dosnt work I can always buy the HOB filter and ahve a fiddle with it, but I'd rather try the sponge filter first.
Oh and re the subtrate, after visiting 3 successive stores I've given up, theres no way in heck I'm painted $20 for a measly kilo of natural looking fine gravel LOl. So I'm going to use black and pink sparkly gravel we have from when i went through an obsession with pink and redoracted my Betta tank to match.
With the heater, I'm going to test out our 25w on the tank. The pet store did have the mini heaters at $30 a pop. Also no chance LOL, a 100w heater costs the same amount.
Gah I always forget to sya something LOL, Further research on the air pump says it does 150l of air per hour, how much circulation would I be looking at?
