Sideeffect of High Calcium on Fish

[freshwater]

What are the effect of High Calcium on the Fishes. If I overdose the PurpleUP will that effect the Fishes like they can get Burned or something else. Recently I have observed that when I put PurpleUp in my FOWLR I saw fish casuality next day and their eyes got blurry and the skin look whitish.
So is their any relationship between high Calcium and Fishes.
My Calcium test kit is not giving me the right result since its expired long time ago so dont know what is the exact Calcium level.
This is a New tank and i am trying to grow the purple coraline on my existing LR.

more likely an effect of poor water quality rather than the high calcium.

You assume your calcium is high,..... have you tested it? Get it tested by a lfs or get another test kit. Why are you dumping Purple up into your tank if you don't even know if low calcium is the reason the coraline isn't growing? Do you even know what purple up has in it?

Purple up isn't going to be a miracle cure for your lack of Coraline. My guess would be poor water quality or poor lighting.

the water chemistry is Good and all the numbers are near zero.

NH3 =0
Nitrite = 0
Nitrate = 0
Phosphate = ~0.1
PH = 8.5
Salinity = 1.023
Temp = 78-82


I have used Purple up in the past on my Reef tank and it did wonders in developing the purple coraline and my whole tank was filled with coraline after I start using it.

My question is that high Calcium above 600ppm can cause issues with Fish Health when Water Chemistry is good. ?? developing coraline is not my issue I know i will get that in few months and I can see the result already ..

It can if you dont measure alkalinity. High calcium will precipitate alk. Low alkalinity can cause fish stress imo. Like 2meq/l and less.

 

[freshwater]

I will check the Alk today . I do have a good kit for that.

I'd worry a bit about that pH reading as well. Depending upon when it was taken, your tank could swing a couple of tenths higher, and that wouldn't be something your fish would like.

I did the reading and its comes out to be 2.25 Meg/L.
PH was 8.4. Do you think I need to add the Alk , i am also dosing 5G kalkwiser once in a 2 week.

I monotor the PH with PH Monitor and never seen higher then 8.5 and
lower then 8.3.

Trash the Purple up, keep calcium at 450-500 and you'll have more coralline than you can imagine within 6 months.

 

[boxfishpooalot]

yes add some alkalinity. 2.25 meq/l is getting low. I use baking soda to raise alkalinity. You should keep your alkalinity at 2.5meq/l at least. Or no higher than 4meq/l.

What test kit for alkalinity? If its Salifert, I recomend you keep the alkalinity at 3.5meq/l because of the issues they are having right now.

I used Salifert Test Kit. I do have Alk powder from Kent Marine to increase the ALK. Will try adding that.

Thanks.

The thing to remember with this hobby is patience. Your corline will grow if condition are within the normal range. I don't like those products that advertise instant growth, etc. If conditions are right you will have a thriving tank.

IMO, just keep water changes up and periodic checks of parameters and don't overreact, meaning dosing like crazy to make up for something a bit out of whack. It is better to change slowly.

High calcium can cause the water to look like there is always particles floating. We had issues with ours being too high before due to a salt problem, but after a switch to reef crystals and a whole new setup that went away.
