Guys can I ask a question
000200C1.gif
Would it be good to do a 100% water change every month if I had an indefinite supply of good quality,filtered NSW.Or would it be better to do less,say 80% 0r 50% every two weeks.

Well 70-80% is better any way,I wouldnt need to drain the tank level down too far then.I also did about an 80% the other day and man did my mushrooms love it.

In this case, I would do a large (70%-80% water change every week, or better still, have a continuous slow exchange 24/7 - that would be as close to ideal as one could get without having the resources of (say) Two Oceans or Ushaka, where they have a continuous replacement of their water.

Think of this. In nature a 100% water change happens every couple of seconds :whistling:

With regard to the above comments, yes, a constant flow would replicate the sea, but in our case any more than 10% weekly will upset the chemistry in our tanks, we do our best to replicate the sea but in earnest we are a million miles away, unless you can have a system with a constant change of fresh sea water, then a 10% weekly change is probably best.

Agree with Hennie, a constant flow like an open system would be first prize, however my next bet would be smaller, smaller 20% changes daily etc. Although the effort might not be worth it for you.

100% water change every month I'd say no. That's one biggish shock every month. If you are doing large water changes daily and the water is consistent then it should be fine. If you do want to do a 100% water change rather change 20%, then next day 40%, then next day 60%, then 80% then as close to 100% as you can.

Howdie Warr.Im glad you're back.I hear what you say,i suppose the land locked guys have no way of such elaborate WCs but i can change unlimited amounts of water as often as I like.Im seriously thinking of setting up a continuous flow,what you think

just you be careful about what flows continuously into your tank bud, a lot of nasties in our ocean.

For me 100% water change will be like in the winter, you being inside a building, warm, cosy, sigarette smoke, old farts...
Then
go outside for on hour, cold FRESH new air, can breath, happy
then take that air inside (leave the door open for a while) go back in and repeat the process.

Sooner or later you will have a cold.

Frequent smaller water changes IMO are the most ideal - 5 to 10 litres a day if you have the time and energy for it.
