Im starting a fish only tank and may want to add small amounts of LR as i go would it be possible or would dechlorinated tap water kill off the bacteria on the live rock?
Be very careful here as tap water is not normally used in marine tanks. Test your tap water to see how much phosphate and Nitrates it contains as I think you will be very surprised. Tap water is different all around the country but all if it contains all sorts of things not suitable for marines. In my opinion, you will loose some of the critters mixing up tap water and you will probably have trouble keeping your water parameters stable over the long term. To be on the safe side, buy some RO water from your lfs to get you going and then buy an RO unit as they are really cheap now (£65).
Hope that helps.
Anyone know of someone who sells RO water and can deliver? or a type of ro unit you can fit to the tap or something?
