Calsium/alk question

[God of thunder]

Peoble always told me that my calsium was too high 490 ppm.
I was also told that i needed to rais my alk level which was low, very low at the time. now i´ve raised the alk to 3.9 meq/l
Is it a problem that the calsium is that high?

That level of calcium doesn't seem to cause animals any troubles, from what I can tell. The tank might have more abiotic precipitation with calcium that high, which would waste a bit of supplement, but that's probably the worst case. I'd probably let calcium drop, though, on general principles of caution.

But how comes it´s that high?

 

[bertoni]

That's a good question. First of all, sometimes, test kits aren't accurate, so a second opinion might help. Also, what's been dosed into the tank, and what salt product (if any) is being used?

 

[God of thunder]

I used to dose iodine, strontium, coral grow and buffer, not any more though, o don´t dose any thing, exept i dosed baking soda to rais my alk

 

[bertoni]

Well, the calcium should drop on its own, if alkalinity is kept up, and the salt mix isn't high in calcium. I'd just wait and see.

I´m using read see salt, some special coral thing

Hmm, that might run a bit high in calcium.

It's also worth checking your SG device:

Some of them are rather inaccurate.

Thanks a lot
