Very high dkh?

Hello all,

I have been cycling my tank for about 3 weeks now, though I had about 60% of the live rock from a friends tank that has been established for a few years. I just added a cleaning crew kit in the tank yesterday and they are cleaning it up great, no fish yet.

Anyway, today I tested my dkh and I got a reading of around 15 or so. Was just curious if this can be harmful being this high, and if so what should be done about it.

Here are my other stats:
35 gallon
ammonia: 0
nitrate : 0
nitrite: 0
SG: 1.025
temp: 79 F
calcium is around 450. thanks.
Edit: PH is around 8.2

 

That is high, what have you been adding to the tank?
Dosing??
You need to be checking your Mg too. How did you get your Ca to 450?
Not many salts can do that out of the bucket.
Are you running a Ca reactor?
Need a lot of info. ;D

By the way, love the pic of your Naso!

 

Thanks Otty, yah I just did one dose of seachem magnesium and strontium for calcium and some vitamin and amino acid supplement. I only did one dose, a little under 2 capfulls of each. What kind of Mg concentration should I shoot for?

Are there any potential problems my high dkh can cause? I'm guessing the only way to get it down is from water changes? Thanks again for the input.

 

Your still cycling, you shouldnt be adding/dosing anything right now. You have nothing to feed/grow!

 

Actually Lunatik, it helps the coralline algae growth, thanks for the input though...

 

Water changes are your best bet at the moment. I wouldn't put in any more additives though. You should test for Mag and bring it up to 1300, the mag will make sure your Cal and pH stay put at the right levels.

The only problem I can really think of, as I mentioned above, your pH will flactuate too much and cal. will drop. BUT even though you need your mag. up, I wouldn't mess with any more chemicals anymore, let your tank cycle and then you can worry about everything else.

 

Don't be adding Mg unless you know what your levels are and I didn't see that test. That will get you in trouble and your tank out of wack fast.
Shoot for your Mg to be around 1400 to 1450 and as Lunatic said don't dose stuff unless you are way out of range on a parameter. You are just cycling a tank and coralline will grow just fine with time and the right parameters.
Don't do any water changes as you will just prolong the cycle. Just let the tank be and it will consume the dHK in time.

 

Thanks for the help to the both of you, karma to you both.
