Why would i need a DI unit? theres not that much agriculture around my area and there is a lot of sand, like builders sand so i wouldnt think my water would contain that many contaminents to begin with.
It will go in the garage and it comes with a self peircing valve, so how do i turn it off when im not using it?
okay its the ro units come and i was surprised how small and tidy it was (never seen an ro unit in the flesh before) any way im nearly there to filling it up backing and acrpod light has come. In sump im only going to have miriacle mud and in my fx5 i think i will keep the sponges? keep the bioballs? as they do convert ammonia etc into harm-less nitrates lol and my dad sees it as a waste gettin live rock for the filter if i have already got bioballs, Plus it has a larger surface area than live rock, dont worry tho coz i think i am going to have lots of live rock in the aquarium and a slightly deep 2-3 inch sandbed to convert my nitrates into yummy N2 gas.
How does that sound coz i really need your opinions!
you have to be very careful using filter media and bio-balls in marines, as if they are left for a while and get clogged up then they do a lot more harm than good. Ultimatly if you want a reef tank, you will need live rock and not the bio-balls. Once you have gone live rock, the external filter will be a nice place to run phosphate remover and other bits and bobs. Live rock will give you far more efficient filteration than bio-balls ever will
yer ok i see your point ill run carbon in one, phosphate in the other, in the last ill put a bit of live rock rubble in the last however if u look at a pic of the fx5 on the net u'll see its surrounded with sponges what shall i replace it with?
