Water Test Results

[Juano908]

Juan, that doesn't sound right. I don't know your total volume, but 2.4 tsp might be alright for a very small nano tank.

With the BRS calculator, assuming you cooked the baking soda, you want to pick "2 Part Alkalinity (soda ash)." The other consideration is that you don't want to raise alkalinity more than 1 dKH per day. So go slow in raising you alkalinity.


EDIT TO ADD: I think I see what you did....dry soda ash. I just assumed you made up the alkalinity solution of 2 1/4 cups of cooked baking soda made up to one gallon with RO/DI water.

Paul I did the calculation for 80 gal of total water volume and yes I did baked the baking soda, 2 1/4 cups of b.s. at 300 degree for 1 hour and then RO/DI water to complete a gallon of total solution.

I don't have any dosing system and i can't afford to buy one now I guest I'll make a simple dripping one for now.

I think it's more simple to make your alk into a solution by adding 2 cups of soda ash(baked baking soda) to one gallon of RO/DI water. Use this calculator, fill in the blanks for your system and Randy's recipe #1 in the drop down menu. Once you have your param's where you want them, start testing for a few days to a week to see how much your system used, and then determine how much you need to dose each day.

Jim this calculator give me an approx. 2.4 tsp to be dose, I did the solution already, now I have to start playing with the dosing to get familiar.

Thanks everyone for your help.

No no no. That is the TOTAL amount to bring it up. Split that amount up over 4-5 days and slowly bring it up. If you hike it 2 dkh in one dose, you can kill some corals. Welcome to the wonderful world of dosing lol. Honestly, once you get it set to the correct amount, you will see your corals explode in growth.

Wish me luck, lol....

Dose as needed it all depends on your tank if its loaded with coral then it's going to burn through alk ,calc

I don't have that much corals, my tank is still low stock and mostly lps and just 3 or 4 sps.

Using the calculator, 80 gal. net water volume and Randy's recipe #1 in the drop down menu, I get 3.8 fl. oz. to raise your alk from 7dKH to 9dKH. I would add half (2 fl. oz.) to a high flow area of your system/sump over the next two days, and check the results each day. It is also possible that between your coral, and any coraline algae you may be using 1 dKH a day. What are you using to measure your SG? If it's a swing arm type hydrometer, you may be getting erroneous results causing you to add too much(/little) salt mix when making up your water for WC's. Assuming your test kits are accurate, this would give you higher(/lower) Ca and Mg readings than you want. I would suggest using a decent refractometer that is properly calibrated using a 35ppt solution(not RO/DI water).

Yes Jim I use a swing arm refractometer to check the SG.....my tank is going to be 1 year old and I don't have that much coraline
...I always wonder why only few tiny patches of coraline.

The relationship between alk, calk and mag is one that drives everyone crazy. I bet once you get that alk up you'll start to see more coralline. I would add enough 2 part to get you numbers to the desired point. Then don't add anything for a few days. Retest. From those results you can determine your systems daily usage of alk and calc. Dose back up to your desired levels and then add the required daily amount to maintain. The most important aspect of dosing is understanding your systems usage so you can maintain stable parameters. The stuff we keep in our tanks don't like change. If you haven't done so I'd advise getting dosing pumps. You can then break down that daily dose over multiple times throughout the day. Dosing manually quickly becomes a pita and when something becomes a pita you start avoiding it.

Well found out I have to dose 1 oz of Alk solution daily to keep it stable at 9.65 dkh....now here is my dosing divice, lol.....

I am going to say to save yourself the hassle of dosing and aim to getting a dosing pump. You can buy programmable pumps for as little as $60 for single head or marine color triple doser for under $200
