Interested to know who do water changes.

If you do them is it a strict regime or just when you have time. If you don't do them, what are your thoughts and practices.

I do about 10% on Saturday every week.  Not sure why, mainly paranoia I suppose lol  it ensures there's always a certain amount of traces being replenished. But given I'm only taking 10% out, it must be doing bugger all really for reducing pollutants.

Kinda tempting to bite the bullet and go Triton or DSR and lose the water changes altogether.

I do very small water changes of about 5 litres twice a day, 7 days a week which work out to be about 10% a week. The water change done when I turn off the return pump, sump water rises up then runs into the emergency overflow.

It’s only about 5 litre at a time so I Just symphony it to the sump manually and also I don’t have space  for fresh salt water in the cabinet...

I’ve been thing of using the ATO container on my cabinet for this, Salinity needs to be less than 1.024

I keep doing 10% weekly and 20% once a month, parameters all good except nitrate which constantly sit too high at 40-50ppm, corals and fish all doing well just numbers driving me mad!

Did 1 on my 4fter in about 3 years.  Not done any on my 6fter in 2 years.   I have a deep sand bed though, so a lot of surface area for bacteria.

Do you dose anything for trace elements?

Im sure he does. I havent done a water change since setting the tank up. i dose 20ml Nyos mag and calc and 55ml alk daily which is keeping things stable and 25ml a week of nyos trace elements personally. I plan on doing an icp test in 2 or 3 months dependant on how things are looking.

Does dosing these element this frequent cost more than good old water changes to keep levels up?

£15 for 250 ml @25ml / week is 10 weeks so i would say no.

however by dosing daily i keep a balance which you dont get doing water changes once a week/ fortnight or month whatever your regime. For me it is more stable. As for cost, well this is the wrong hobby to worry about a few quid lol 😁🖒

Buy the salts rather than premixed! So much cheaper.

That's what my thoughts were, however not knowing enough about dosing I couldn't do the math.

Assuming the above dosage is only one added element, so depending on what is dosed the numbers could change drastically?

I make my own saltwater from rodi and would have just liked to know the workings on both dosing and self made.

Do explain ;)

Yes the numbers change between each element, and ofcourse the ammount per 1L of water is different for each.
I mixed mine up into 250ml dosing bottles ( with 5ml markings on the neck ) to make it easier to manually dose.
