low cal ?

[flathead31coupe]

i have a bb system, i have been doseing b inoc 2 parts for over 3 weeks, still cant get cal up its around 380 or so, so i decided to dose mag,thought it might help bring up the cal. no luck, doseing mag about a week.....any thoughts

What is your Mg level? If it is low it is hard to get Ca up and keep it there, It takes alot of Mg supplement to get it up, same for Ca if useing 2part. here is a calculater.
Reef Chemistry Calculator

just got back from the pet store they ck my water, they said the cal is almost 400, but the mag is 1800, i dosed it lastnight, all other parameters where spot on...maybe i need to give the mag time to adjust,

 

[flathead31coupe]

after haveing the water ckd and the mag was at 1800, i quite dosing the mag but still dosing the cal. going on four weeks, still 380 for the cal is all i can get,mt? is is that from me being bb for 6-7 years, or what, or di i give it time....i wouldnt think it would take that much of cal to raise it, bur it was very low to start with

1800 is high for the Mg so it is not do to low Mg and Mg gets used up at a much slower rate then Ca and Alk. Did you use the calculator I gave you to tell you how much Ca to dose to get it where you want, and how heavy of a Ca load do you have in your tank. Also dozing Kalk for your Mu water can help maintain your Ca once you get it to the level you want.

i didnt use the chart, i went by the bottle, 1ml per 4gal i was doing 15ml of each, for 63 total gal,not counting lr displacement atleast 50pounds of lr...all i have is some green spong, and two green shrooms very small, thats its and lr....

What did the chrt/calculator say, the bootle instructions maybe on the low/cuatious side.

the chart said 875ml not sure

 

[flathead31coupe]

not sure where to go from here,

 

[RBursek]

875ml is what you need to dose of Ca if that is what the calculator said for the product you are using, read any cautions at the bottom of it.

And hopefully you have read this thread as well:

i cant think of why the directions would say to use such small dose, 1ml per 4gal,i have about 55gal total and the chart would say to use 875ml total..

 

[flathead31coupe]

so thats like the whole bottle of both b inoc part 1 and 2

 

[RBursek]

First you do not add both, you get your Mg at the level you want, then the Ca, then test a day latter for Alk. The low dose on the bottle maybe to maintain a given level, not to increase it to a higher level, the calculator is very accurate, it takes so much more to increas Mg or Ca then to just maintain it.

so if the mag is at 1800 what will lower it? then what do i do?

Mag will slowly go down as calcium carbonate is consumed.

I would just not dose and let it come down.

You can add your Ca now, what I ment when I said get your Mg to a appropriate level was if it was low, because if it was low it is hard to get Ca up and keep it up, so now that your Mg is at 1800, which is high but okay, dose your Ca to get it where you wnt, as Bleaslbob said your Mg will come down on its own.

 

[flathead31coupe]

so rather than go with the 1ml per 4 gal for 55 gal, use the chart that wants me to use 1100ml....

 

[RBursek]

If that is what the calculator said for your product and look at the cautions at the bottom, it may not want you to add that all at once. I do not know how many times it has to be said.

using a test strip tha alk was off the chart......what do i do?
