anyone doesn't do regular water changes?
 

Hi
My tank parameters are stable, I have not done any water changes for the past two months. I do have some softies, lpl, sps. I do add mg, ca and buffer. any thing else i should be adding
( trace elements)?

Thanks for the help

One of the main reasons for WC is to replenish trace elements

I do them once a month. I dose for alkalinity and calcium but when I do my water change I usualy have to cut down the dosing for a few days.

20% once a month work well for me. I can see when the corals need a water change because the vigor is a bit off. If you see no ill effect then you probably don't need to do a water change that often. It all depends on your own aquarium need and chymistry.

Some people don't do regular water changes and have beautiful tanks. I don't know how they get away with it.

I think soft coral dominated tanks can get away with infrequent water changes without many problems.

Although I have seen great SPS tanks that do not get water changes, so who knows what is going on. Most of the really nice SPS tanks, however (in my opinion), get frequent water changes (at least once per month).

anyone uses trace element replacement ?
if so what and how much?

It's said that you shouldn't dose anything you can't test for and that water changes are the best method for replenishing trace elements, so I don't think very many people do it.

I do changes once a week. However, I don't have much of a bioload and I have been doing some trending for elements to see how the water reacts over the week. I'm thinking I'm going to push it to 1 1/2 weeks per water change and see what happens. Maybe push it to 2 weeks. Though I do have a clam and 2 SPS in my tank. I'll keep ya posted when I push it further.

I do mine once per month. I dose Calcium, Magnesium, and alk

I have done 20% weekly water changes since startup. Thinking of moving to 2 weeks, but we will see. I only dose alk right now. Ph and alk are low, but everything else is good. I don't add trace elements as I do the water changes so often. I don't like the idea of constantly adding stuff to my tank with no take away.
