Calcium won't budge

[Whatnow]

Okay my calcium level on my 75g will not move above 340ppm. I've tried dosing 2 part Seachem Fusion and it got my dkh up to 12 and calcium to 340 so I stopped using part 2 and kept using part 1 for calcium and a week later it still hasn't moved. I only have a Duncan, 3 zoa's and a green toadstool leather all small frags. I've read about having lower levels of magnesium not letting your calcium raise.

ammonia 0
nitrites 0
nitrates 10
calcium 340
Dkh 11 after water change
ph 8.1

Also have 100 lbs of reef saver rock/cured live rock and running 90 lbs Ocean Direct live carribean sand.

check your mag levels and see where they are at.

What kind of test are you using?

 

[Whatnow]

I don't have a mag test kit yet.

Your not going to raise calc unless ur mags in range its without a doubt low

 

[tankstudy]

I recommend not dosing any further till you can test magnesium. More then likely its your culprit but its always safe to test to make sure.

 

[Whatnow]

without a doubt low

kinda thought that so I'll order a mag test kit. if it is low whats the best way to elevate magnesium.

 

[tankstudy]

There are lot of products out there that just increase magnesium if I'm not mistaken.

Less then 100 ppm a day thats the "recommended limit ,dont dose anymore untill u get ur mag up

I was talking about your calcium test kit..

 

[Sabellafella]

The best way usually is with waterchanges because its kinda expensive to dose, but ur salt mix is obvi9usly low with mag, so get a supplement like tech m or bionic,

I use the purple topped Instant Ocean salt mix- but almost out should I make the move to Reef crystals?

 

[tankstudy]

Reef crystals starts at much higher concentrations. Its also what I use. Reef crystals also tells you the approximate numbers for the crucial parameters we test for based on your salinity choice. This is also a good way to test if your kits are reading properly.

 

[cplatts32]

Was just asking because sometimes people overlook their poor or expired test kits and start making changes to their tank when the only problem was with their test kit..

And +1 on water change...

What kind of salt do you use?

 

[cplatts32]

Go reef crystals!

This is probably your problem, crappy salt

I use rscp for bi weekly and esv if i go long without doing a water change, i acually grabbed a bucket of the regular IO because the redsea contains high maganese and i dont run gfo, i made 180 gallons from the IO and the mag is around 1300, what are you using to measure sg?

 

[Whatnow]

crappy salt

sg? sorry new to reef tanks.
specific gravity? refractometer
