Dosing [NOOB] Questions

Hello Folks!

So I've always relied on water changes to replace any needs in my tank but now I am questioning whether or not should I start dosing.

I got a deal on the BRS 1.1ml/min dosing pumps, got two of them. I've albo bought the PHARMA KALKWASSER STARTER PACKAGE (https://www.bulkreefsupply.com/2lb-k...ef-supply.html) from BRS but I am not sure when/how should I use it?

Can you guys help me with some guidance?

Thank you a lot!

Only dose when water changes are not able to keep up with consumption rates (Alk, Cal, Mag).

Once you determine you must dose to supplement the water changes you'll need to calculate the consumption rate by testing a few days to a week apart and divide the difference in results by the number of days. That gives you the daily consumption rate of that nutrient.

Example 8.0 Alk drops to 7.0 in 5 days. Consumption rate is .2dKH daily. Use the BRS online calculator to get the dosing volume for your product to match the consumption and spread the daily dose out over a few doses per day. Viola.

I agree that the best way to dose is by measuring the alkalinity regularly. Testing every day for a few days might get a trend line, but many tanks consume very little alkalinity per day when starting. Some tanks go through 2-3 dKH per day. The range is very wide.

I test Alk, Calcium and Magnisum each week just before the weekly water change (to understand consumption) and then again, a few hours after the WC, (to understand the effect of replenishment via WC). I do this and record for 4 weeks. Then average, and divide by 7 for my daily rate.

At this point, I just dose the daily and do a check once a month to see if the Stoneys are consuming more yet, then all over again.

DO NOT dose what you do not measure. What are your current levels and what is the consumption? If you do not know those than you should not dose.

Yup. First step is to buy Alk, Mg, and Ca tests [you will get a million opinions re: which. I have tried most and have always circled back to Salifert]. Kalk is a great place to start IMHO, but through a stirrer as part of your evaporative replacement. Using your doser for the kalk portion rather than an ATO will help prevent a disaster. Once you get everything dialed in, you will only need to routinely test for Alk. If you add a lot of CaCO30-consuming critters, you may need to add a 2nd source of Ca/Alk. I would recommend continuing to dose the Kalk [in the event one of your sources fails, it will prevent a rapid fall in parameters]. If you choose to add a Ca reactor down the road, then the kalk also will help mitigate a significant decline in your pH. $0.02
