Water Changes modifies parameters?

[AquaWave523]

I just purchased a few softies and a 2 part doser (C-Balance) for calcium and alk.

1.) My question is regarding water change...I was told that if i do frequent water changes, it keeps my stronium, Iodine, magnesium and other water parameters in check. Then I would really only have to check for Calcium and Alk levels? Is this correct?

2.) I will dose until the readings are correct...how often do I have to dose? ( i know the obvious is until the reading is correct, but on average how often do you guys dose your tank?)

3.) I heard dosing isn't really required for Softies...is this true?

1. Yes and no. This all depends on the salt you use and other extraneous factors I won't get into for the purpose of this discussion. By performing regular water changes you will replenish any of those elements which your reef may use IF the salt you are using is already rich in, or makes up to, the appropriate levels. You will want to monitor your temp, sg, ph, alk, nitrate, phosphate, and calc levels.

2. You really don't need to dose. I have an 8ft softie reef and dose it by feel with 2 part. Once your parameters are stable, you can dose once or twice a week IF your reef needs it. Keep testing. Make sure your alk isn't two high before you randomly toss in more buffer, and always keep in mind your alk may drop at night.

3. Nope. Absolutely no need in my opinion. It's really a personal preference. That being said, keep in mind Iodine has long been know to promote zoanthid growth.

One thing that you haven't touched on with regular water changes is the added benefit of maligning any alleopathy(chemical warfare) that may occur in a softie system.

Good luck!

1. As far as calcium goes it depends on your reef inhabitants. Some corals and reef animals will use Calcium faster than the water changes can supplement it.
2. I would dose until the params are in check and have stabilized then reduce your doses and dosing size until you get a maintenance dose.
3. Softies don't require calcium but zoas will open better with the addition of strontium according to some research I have done. I have not tested this theory yet though.
