its only a little nano planted tank - so doesn't really need to be fancy or pressurised. Id only considered the fluvial because i found it for $20USD.
I really don't have any room in my budget for canisters looking at it long term really. I use a lot of yeast and sugar in bread making anyway - so its not like those are an extra cost for me, where as canisters are - so really DIY or the Nurtafin are better options. the Nutrafin system was going to be 40 something NZ including postage, which is only a little more than id spend buying stuff for diy anyway, and its a whole lot more preschooler investigation and accident proof.
