How fast can I raise alk levels?

[Floyd-]

Trying to get my alk up and im worried about bumping it too fast and shocking the system. Currently im at 7.4dkh and want to get up to about 9dkh. I'm using Brightwell alkalin8.3 liquid at the moment. Looking into new products to use going forward.

.2 - .3 per day TBH.

.2 - .3 per day TBH.

Ok, ill have to work the math to see how much to dose over the day to get it up.

From what I see it says 1ml in 1gallon raises alk by 3.1dkh.
So adding 1ml to my 175gallon tank raises alk by .0177dkh.
Adding 17ml should raise it .3dkh a day. 17ml a day for 5.3days should get me to 9dkh from 7.4dkh starting point.

That sound about right?

what salt are you using and do you do water changes routinely?

Fritz RPM Pro blue box. Normally once a week 10% but lately its been about once a month to keep my nitrates and phosphates up a little.

wow you have fish only and that much consumption. i would do water changes bi weekly test a few hours after the water change and start dosing a bottled two part immediately after to keep the levels the same. but your not keeping coral so its not a big deal maybe dose a larger amount twice or three times a week its all up to you.

I have Soft, LPS and some SPS coral in the tank. I didnt dose for awhile and now apparently i need to supplement again. I turned the pump back on and loaded the new schedule and set an alarm to check in 5 days.

Reminder to watch your pH as you raise Alk levels.

Rodger that. Right now its at about 8.0 at best.

Red sea has a good and easy ALK mix

You would dose 7ml for 175 gallon and this would raise .1 DKH

I have been doing this for months now and my Alk is finally stable and super easy to dose.

Do you use the liquid or the powder?

I didnt see him mention fish only tank??

OP ,, if your tank is fish only why do you care if the tank is 7.5 or 9.0 ALK ????

Typically people are messing around with ALK levels for the coral and inverts . Fish would be fine at 7.5 or 9.0 to be honest they probably dont even notice haha

When i had a couple spikes in alk from dosing incorrectly i went 8-12 over night a couple times. In 3 years i have had ALk levels from 7.3 up to 12.8 the corals are noticeably happy or upset. The fish have been the same the entire time " Fat and happy " lol

Not sure where people are getting fish only from my comments?
I have a 175 gallon tank with fish and Soft, LPS and SPS corals.

You just don't want to raise it more than .2 per day so that you don't stress any corals. Depending upon your Alk mix (soda ash, etc.) it can cause a spike.

The liquid and its the Foundation B

Positives - Super easy to dose and very accurate
Negatives - Expensive

I love it !!!!!!

My local store carries this in 1000ml bottles I believe. Once I burn through my Brightwell bottle soon I might try it out.

For your 175 gallon tank the dosing will be super accurate and easy with that nice number because you dose based on 25 gallon incrimants

Also . You will want to test Alkalinity in your tank everyday for about 10 days straight beforehand. This will give you a really good idea of how much ALK your tank is consuming daily . Then dose accordingly to maintain the range you want in your case 9.0DKH

Im going to slowly bring it up to 9dkh and then stop dosing and see where it drops over a few days and then calculate daily usage.

Yes good plan but do a few tests over a 5-10 day span so you have a pretty good idea what the daily consumption of ALK looks like
