RO Units

[sniggib]

Hia,

My nitrates were very good before i went to uni, 3 years ago. since then as i said my tank took a bit of a back seat. As im now back from uni ive got back into doing the tank myself. Nitrates at the last count were very high, in the 50-100 ppm region probably tending to the higher (hard to read the colours i find), using a salifert test kit.
So since then ive done a full clean out, changed all the back out, removed live rock rubble, added the canister, rearranged live rock etc. Im due to do a test today so will see what it reads. Also purigen has now been running a few days so hopefully that will have helped. Im intending (and have started) to do water changes approx 20% each day for the next week (hence the RO unit).
I feed flakes, and frozen brine shrimp, either a few large flakes broken up or 1 cube of BS (although i think i might half this).
I should really start a tank thread with all this :-)


Thanks for the help

Cheers,

Matt

mine was up at 50 a good while ago.I done the big water change method but done it slightly
different.I took out 40% of the water, put in 20%, removed 40% then filled back up to the 100% level.
this dropped my nitrate levels to 5 with no harm to my corals or fish...just needed a little over six barrels of water lol

That sounds a good method, might go that way instead of a lot of smaller water changes.

Cheers,
