Saltwater Water Changes
So I'm looking at starting a new 400-600 Litre salt water reef aquarium. I'll have a sump with this aquarium and a protein skimmer.
I know how much salt I'll need to get started from looking at the salt buckets at my local pet store.
I have what may possibly be a really stupid question.
How often will I need to do a water change?
On my tropical freshwater I do a weekly water change of 1/4. If it's the same that'll be a lot of salt and cost.
