For SPS keepers

The best reef tank app for SPS is a stability instrument

Acros don't forgive drift. Reef Trak is built around the things SPS keepers obsess over: tight alkalinity trends, dosing precision, consumption tracking, and a photo record of every colony.

SPS keeping is trend management

Every experienced SPS keeper says the same thing: the number matters less than the line. Alkalinity at 8.2 is fine; alkalinity that was 8.8 last week is a problem in motion. SPS tanks fail through drift — slow consumption shifts as colonies grow, a doser losing prime, a salt batch that mixes different — and drift is invisible without a trend record.

  • Tight custom ranges — set your alkalinity band as narrow as your tank demands and get alerted the moment a log lands outside it.
  • Consumption visibility — dosing history against parameter trends shows demand rising as colonies grow, before depletion shows.
  • Every change dated — salt switches, dosing adjustments, new colonies: when chemistry moves, the cause is in the timeline.
  • Controller and Trident imports — automated readings join your manual tests in one history.

When something goes wrong, the record answers

Tip burn, paling, STN — SPS problems demand a timeline. What was alkalinity doing for the past three weeks? What changed in dosing? When did that colony's color start shifting in the photos? With everything in one per-tank history, diagnosis becomes a lookup instead of a guess — and prevention becomes a habit, because the trends warn early.

Frag and grow-out systems get the same treatment: unlimited tanks means your frag tank's history is as complete as the display's.

SPS tracking — FAQ

What parameters matter most for SPS?

Alkalinity stability above all, with calcium, magnesium, and steady low-but-present nutrients close behind. Reef Trak tracks the full panel with custom ranges and alerts tuned as tight as your tank needs.

How does Reef Trak help with alkalinity stability?

Trend charts make drift visible early, custom ranges trigger alerts on out-of-band logs, and dosing history sits on the same timeline so you can match consumption changes to dosing adjustments.

Can I track individual SPS colonies?

Yes — each colony gets its own livestock record with dated photos, so growth and color history build per colony.

Does it work with my Apex and Trident?

Yes — Reef Trak imports from the Apex ecosystem, so automated readings and Trident results join your manual tests in one history.
