Two questions: Salinity and wavebox

[Edward Smith]

1. Doing a 50% water change (125g). Tank salinity is 1.024. New water is 1.027. Don't feel like diluting the new water to lower it. I will if I have to. Is this close enough? (softies, LPS, SPS and fish).

2. If I get a tunze wavebox, do I still need powerheads or will it provide all the circulation the tank needs?

Thanks for any/all input!

If you don't dilute to match salinity you may stress everything. What is the temps of the two solutions? Different temp affects salinity. I don't have a tunze but what I have read they should take care of flow just fine assuming you already have a sump return.

Ed,

You still need the flow from the ph's. The wavebox just moves all the water slowly back and forth. By the way the waveboxes are great! If you have a closed loop system maybe the ph's are not necessary.

Ed- That water change at that salinity should adjust the salinity of your tank water to 1.0255. Not a big change, but I'd probably dilute the new water to 1.026 just to be on the safe side.

I agree


as for the salinity diff I wouldnt worry about that at all thats how I go my salinity up to where I wanted it to be

but they are doing a 50% wc. A bit to fast in my opinion

It will only raise his salinity about a point which wont make that big a difference

Its actually a point and a half . I agree that it wont make a big diff, but I dont understand why it would be so hard to add a little fresh water to the newly mixed salt water.. Maybe bring the salinity of the new water down to 1.026?

Hard? No.

Lazy? YES!!!!

I'll water it down a little. I just didn't know if closing this gap was over zealous or neccessary. I've done alot of work and worry for things that have been unneccessary and trying to break the habit.

I.E......spending two weeks researching the best bulb for my algae scrubber :crazy1:

DA! :smokin:

Tank salinity 1.025, new water 1.025

I didn't realize the difference was one 5g bucket of additional freshwater. I'm not THAT lazy.

Thanks for all the help.

Ed, 10/21-28 I'm flying alone here. Stop by any time to see the wavebox if you like. Yes, you need other circulations. You'll see why.
