Is calcium a killer ?

[Scotty333!!!]

Guys
As some of you know, I’ve overdosed calcium to the tune of 800ppm
I’ve checked this against lfs test kit and the results are 100 apart

My question is , after a 33% wc tomorrow it’ll be around 670ppm

Would you add corals with this value? I’m looking at achieving a monti heavy aquarium and wonder if they would adapt to the high calcium and use it up or they’d die instantaneously ?

I don’t really want to do another 4 big water changes to get it to nsw values

I’m thinking I’ll try a frag for a couple of weeks and see how it gets on before I shell out for a box full

What’s your thoughts please

High Ca isn’t a deal breaker. As I mentioned in the other thread, just keep an eye on your Alk.

40% change done , stats to follow

Here goes

Mag 1380
Po4 0.15
No3 25
Kh 9.3
Calcium 650
Salinity 1.026

Gonna add a monti frag see if it survives while I’m away a week

Nice, I like that Acro (but, I'm biased).

 

[Scotty333!!!]

Well it that survives I can keep anything I guess , currently it’s in line with a wave maker so it’s being blasted and I don’t think polyps will extend , I think I’ll move it to a less breezy place

Careful on the massive WC’s that is a killer.

IMO, bring your MG high, 2,000 is fine.

Keep an eye on your ALK, you likely will need to add. Just keep it at 7 or higher


Do everything slowly and in moderation. Trying to fix this quickly is likely to be more detrimental than riding it out.

Yes I agree, the big change today was absolutely necessary with calc at 800
Now I’ll drop down to 10% weekly changes until everything’s correct

 

[Scotty333!!!]

Just got back from a week vacation and tested water params

Salinity 1.020 !! Wtf?
No3 40
Po4 0.25
Calcium 500 weird was 650a week ago
Mag 1155 also down from 1380
Kh 9.3

 

[Scotty333!!!]

Gonna add salt up to 1.026 over a few days
Acro is still alive

Salinity 1.020 !! Wtf?

You have a sump correct? Is the water level in the sump where it should be or high? If high, and you have an ATO, this *could* explain a drop in salinity. Alternatively, if not high, but you have a slow leak somewhere it could also explain the drop in salinity.

Additionally, I don't recall how you're testing salinity. How are you testing it?

 

[Scotty333!!!]

Yes I have a sump and a top up chamber attached , the ssump level is spot on and even an inch or too high wouldnt justify 0.006 drop
I’ve tested a new batch of saltwater and it came out at 1.025 as expected
Refractometer calibrated with rodi

 

[griss]

That's bizarre then. Only thing I can think of is the small leak somewhere allow saltwater to escape and your ATO replacing it with RODI. But, you'd think you'd notice a leak.

 

[Scotty333!!!]

All I know is anything’s possible in this game , no evidence of a leak but it’s a corner tank and I can’t see down 2 sides

 

[Vinny Kreyling]

You want to calibrate your refractometer with a solution close to actual saltwater for best results.

 

[Scotty333!!!]

Calibrated with rodi, checked with lfs and got same , 3kg of salt in 30ltr container came out 1.025
Can’t check anymore , it’s definitely 1.022
I think cos I’ve been emptying my skimmer a lot due to carbon dosing it’s slowly reduced salt

Possible. I forgot you were carbon dosing.
