Exactly's ZEOvit 90G has reached the end :(

The BRS 2 part alk solution consists of both carbonate and bicarbonate ions. Both are used in calcification and in buffering the CO2 level in a tank. educated guess here; but im guessing they might have more carbonate than bicarbonate if they say it will raise your pH? still not a bad thing at all.

Your pH will not go much higher. I have seen it go as high as 8.7 in one guys tank over time but that was due to a consistent alk overdose. still no issues for any organisms in this case.

And lastly, since your using the 2 part you might want to adjust your dosing ever so slightly. Every tank is different and in theory the two parts should be used in the exact same amounts of each but this is not always the case. In my dad's tank he would have to dose a few mL more alk than Ca to maintain levels. In my tank I have to dose slightly more Ca than alk to maintain levels.

 

also enjoying the info above!

 

To be honest, I'm kind of suprised that you have to dose at all. I dont see a huge coral population that would deplete your levels very fast, and I know you do a 10% weekly WC as well.

 

No I havent really had to start the complete BRS 2 part yet. I still had some Reef Builder (Seachem) left over for alkalinity time to time until recent. Only the BRS Calcium dosage. It's still a fairly new tank, so Im trying to figure things out.

The quick param check today:
Cal:420
dKH:6
pH:8.4
Mag:1380

The wife is responsible for the param check and she goes, "I must have messed up somehow last time, the mag is 1380..." I was freaking out over nothing.

Im really nervous about dosing the BRS alkalinity with having pH at 8.4. Baking soda is the way to go? Any soda would do? And what is raising the pH to begin with?

It's really time for something nice. A few SPS frags maybe? I like digitata, red planet, green slimer, tort acro... are they gonna be ok??

 

Forgive me if this has been discussed, since I haven't been in on your thread in awhile. But why do you have 2 part already, and why are you considering it? I would think kalk would keep up with your corals just fine. I'm no expert so maybe I missed something but it seems like if you needed to dose, kalk in an ATO would work for you at this point.

I see you added a BP reactor, what were your nitrates before and after the reactor?

Now

When I had 29, I got the Seachem Cal and alk additives. After I finished the Cal bottle, ordered the 2 part from BRS. But the Seachem alk lasted until recently. Now since the dKH is getting low, Id like to start using the BRS alk but the site says it will raise pH. I hope it will clarfy things a bit.

As for the BP, Nitrate nor Phosphate was ever detectable. But there were signs that they were present (Cyano and algae film on the glass). But the cyano is gone, cleaning the glass every other day instead of everyday.

 

Okay I see. Was the 29 heavily stocked with hard corals? Most ppl only switch to 2 part dosing once kalk won't keep up with the demand from their corals. Kalk will raise cal and mag at the same time, but also raises ph if added too much too quick. Which is why ppl drip kalk. But as you add coral and your coral grows, your demand goes up, thus you need to increase how much you dose. With kalk, you can only go so high on your dosing before it starts to spike your ph. That's when ppl make the switch to 2 part dosing. Kalk is a lot cheaper than 2 part and easily dosed with an ATO unit which is why a lot of ppl go with it until they are forced to switch to 2 part. I know a lot of ppl that dose 2 part have dosing pumps which can spread the dosing out and dose it slower. Dosing 2 part by hand like you are wanting to do, may or may not be hard to do since you may need to do many small doses to keep your ph from going to high. At least this is the info I have gathered, I may or may not be wrong.

First of all, thank you for typing that much on your Droid3

No the 29 was not heavily stocked at all, I just didnt know, heck, I still dont know much about dosing obviously! I've read on this forum someone saying that he doses Seachem stuff and I went with what he was using when I wanted to adjust the param. Since I have a ton of 2 part left, Id like to use it.

I ask this again, Im really nervous about dosing the BRS alkalinity with having pH at 8.4. Baking soda is the way to go? Any soda would do? And what is raising the pH to begin with?

 

LOL, that's why I will only use a smartphone with a physical keyboard ;D

Yeah since you already have the 2 part, you might as well use it. I just know its alot more expensive than doing kalk. But anyways, ya your ph is just a touch high, and sorry but I'm of no help in that area. LOL. I'm still learning water chem.

 

Added three chromis today!! Do you think I need more since they like to be in a group, like 2~3 more maybe?




Picked up a leather as well, post some pic when I have a chance.

And the mystery still remains, I really havent been dosing alk other than Seachem Reef Builder, but the pH is at 8.4. So it makes me nervous to use the BRS alk. Since the KH is on the low side (6dKH), just go ahead, use the BRS alk and see what happens?
