I’m planning a tank upgrade very soon 120 gallons to 150 gallons and I’m wondering when to restart dosing core7? I will be using all new water for the new tank. Should I start the core7 day one or wait? I’m assuming ALK will fluctuate a little the first week or so? Maybe just start with water changes for the first month? Any thoughts will be appreciated thanks.

So your using it now with the old tank.
Transfering everything over.

I would start from day one, and continue with the same dosing ammount and schedule.

Basically your just doing a rip clean with a 100% water change.

Actually I’m using core7 the other method but is almost gone and the new bottles I bought are the core7 original. I’m not sure what the difference is.

The other methods are primarily for use when a calcium reacter is used, and also not a fuge as I understand it.

I started my tank with Triton and a fuge, so I never researched the other method implementation.
I am sure others will chime in on this.

That makes sense I do have a big refugium and I find myself still dosing ChaetoGro.

How much core7 are you dosing and when?

My Apex does the dosing throughout the day.
I have the time differential set so they dont dump at the same time.

I use a lot of ALK around 50ml a day.
Ca and Mag are in the 20ml range.

Wow interesting I thought equal parts are recommended? I don’t have Apex or any fancy controllers. I was dosing core7 by hand for three months and I just got a GHL dosing pump my life has been improved.

Yes I knew the equal part question was comming.

You will find in time that it will change. It has to.
My CA and Mag were skyrocketing doesing equally to keep up with the ALK consumption.

If you go through the Triton forum you will see most of us alter the dosing
and Jullian will agree.

I was thinking it was just my core7 other method but my ALK is around 7.5 and calcium is over 500.

I'm not sure how exactly you are calculating that volume, but it is supposed to be 2:1, not 1:1 since there are two alkalinity parts:

" For mixing 3a and 3b: Should you wish to combine 3a and 3b together in order to save a dosing unit, please note that soluton must dispensed at twice the amount of the others. "

Yes very true.
When I started I had 4 dosing pumps, and my regimen was around 10ml each.

One pump failed and I had to mix and then doubled the alk dose to 20.

When my ALK was depleating faster than the rest I raised everything by 5ml a day. The following weeks my alk was ok but the Ca and Mag were getting out of hand. Had a Ca of 530 and the Mag was at or over 1500 if I remember corectly, without looking at my log.

So I cut the Ca and Mag down to 5 or 7ml a day and let the alk alone.
After a few weeks it stabilized.
For what ever reason my tank uses a lot of ALK in comparison.

My first few ICP tests were like oh my god everything is wrong.
Now everything is in the green with no red or yellow.

Does nitrate accumulate? You using a sulfur denitrator? Aside from water changes, that's about the only way there can be significant alk demand that is not also reflected in the calcium demand.

I will test today and see where they are.
But that being said if I remember my nitrates were around 10 when this was going on.

So the only filter I run is a bag of carbon next to return pump no skimmer. My nitrate doesn’t go up by itself but I did add a bunch of NeoNitro and NeoPhos because of Dino. I haven’t seen Dino in months but I’m sure they are still around. Should I start with all equal doses of core7?

Dosing nitrate and, to a much smaller degree, phosphate, to the aquarium will tend to boost alkalinity.
