Reef chemistry, written down.
Practical, chemistry-accurate writing on dosing systems, batch traceability, and the operational side of reef chemistry. From the BioForge bench in Hialeah, FL.
Hanna vs Salifert alkalinity: which one do you trust?
Same water, two tests, two different numbers. Why a 0.3 to 0.5 dKH gap between them is normal and documented, what accuracy and precision actually promise, and which number to run your dosing on.
Read the article →Tin showed up on your ICP test. Here's where it's coming from
The scary studies are about a different tin than the one your plumbing leaches. The usual suspects, in order of how often they're guilty, and the fix sequence: confirm, hunt, remove, dilute, retest.
Read the article →How often should you actually ICP test?
Every 2 to 3 months for a stable tank, monthly when something's wrong, and always about 4 weeks after a fix. The lab recommendations, the reasoning, and why one lab on a schedule beats three labs at random.
Read the article →Why is your alkalinity dropping so fast?
Fast drops are usually growth, sometimes precipitation, occasionally a bad test. How to measure your tank's real daily demand in five days, and the warning signs that separate thriving from crashing.
Read the article →AquaBiomics is closing. Here's what your tests can still tell you
Hobbyist microbiome sequencing shuts down at the end of the summer. What DNA testing showed that ICP never could, the deadlines if you still hold a kit, and how to keep reading your tank's biology when nobody is watching it directly anymore.
Read the article →How to read your reef ICP results, from any lab
Forty-plus numbers, three unit systems, and a color-coded verdict you didn't ask for. Here's the reading order that turns any lab's ICP report into something you can act on: salinity first, then the big three, then nutrients, contaminants, and traces.
Read the article →Your ICP results are back. Here's the order of operations.
Five elements flagged and a strong urge to fix everything tonight. Slow down. The 30-day sequence: contaminants and salinity first, then alkalinity stability, then nutrients, then one trace at a time, then the retest that makes it all readable.

Four labs, four price points, four sets of "ideal" ranges. What actually separates them, what OES vs MS buys you, and why the lab you stick with beats the lab with the best marketing.
Read the article →Why identical ICP results can mean two different tanks
ICP testing measures chemistry with real precision, but it can't measure the coral biomass, growth rate, and trace element uptake driving your tank's actual demand. Here's why that gap matters, and how to plan around it.
Read the article →Why a fixed dose won't hold your tank
"Dose X to raise Y" is real chemistry. "Dose X daily to hold Y" is a population average dressed up as a constant. Here's where the fixed-dose habit breaks, and why your tank's living demand always gets the last word.

A practical guide for reefers running BRS Pharma, ESV B-Ionic, Tropic Marin Original Balling, or similar systems. Real conversion math, gradual transition protocol, and the chemistry behind why it works.
