Buyer guide
Best dosing pumps for reef aquariums
Compare four-channel dosers by calibration, control, channel count, ecosystem and current UK price.
Decision guide
Do you need to dose a reef tank?
Work out whether water changes are enough, whether consumption is measurable and when automation is premature.
Chemistry
Two-part dosing for a reef aquarium
A cautious workflow for measuring consumption, splitting additions, separating solutions and monitoring salinity.
Alternative
Calcium reactors versus dosing pumps
Compare two-part simplicity with CO2-reactor complexity, capacity, footprint and failure modes.
Automation
Best aquarium controllers available in the UK
Compare controller ecosystems by monitoring, power control, expansion, app dependence and total cost.
THE AUTOMATION RULE
If you cannot detect a failure, you have not automated safely.
Label every line, calibrate each head with a measured volume, keep dosing points away from each other and retain a way to stop the pump if a container empties or a probe drifts.
