Help clear something up

[SoGaReefer]

I think I received a funky batch of salt as when I transfered to my 75 gal display with 100 gal total volume system my alkalinity is only 6.5. I made up a batch of the randy holmes Farley alk with 297 grams of baking soda on 2 gal of RODI water per the website.

After that there are no more instructions so I used the listed calculator and got the results shown.

How do I dose said results ?? All at once x.xml a day ?? Twice a day ??? Someone please help

Is there anything in the tank?

Personally I'd break it into 4 doses and dose twice a day over two days.

Yes fish and a handful of Zoa's, couple chalices and 2 or 3 sps frags one torch one acan and one echinata. All small frags

So 71.25 ml twice a day for two days

I usually just use dry baking soda mixed with RODI in the quantity I need to make up and then use Randy's mix for continuous dosing.

But yes, if your calculations are correct.

My question though: you stated above that you mixed 297 grams with 2 gallons of RODI?

Typo 1 gal per website instructions

Also, keep in mind that a 100 gallon aquarium does not have 100 gallons of water in it. When I was running my old 135 gallon plus 30 gallon sump, when the rock, sand, air space above the water, and sump equipment were all taken into account I had 100 gallons of water total.

In my 70 plus sump I estimate around 60-65 gallons of water.

80gallon tank with 30 gallon sump so figured 100 to be safe may be a little less plan on ordering new salt and doing water change anyway just want to get somewhat leveled out

So essentially I could put 4.8 tsp in 1 gallon of RO and use it to top off for same results ??

I usually do 1.5 tsp in a cup or cup and a half of RODI and mix it good then slowly add it to the sump. Baking Soda mixes easily so it doesn't need a lot of water to mix with.

I'm not positive but I believe Randy's recipe is likely to make it easier to dose - 1mL calcium dosed to 1mL alkalinity dosed.

How much does that raise or maintain your alk??

How much does that raise or maintain your alk??

It raises my alkalinity approximately 0.5 dKh per 1.5 tsp in my tank. I also dose 30 mL or so of Randy's 2 part daily spread out over 20 doses.
