Crowd thread digest
What the crowd said: cleanup crew combos and black beard algae
What’s your best combo for a clean-up crew? What’s the best for BBA? Ty.
Thread quality (estimated)
0 to 100. Qualitative, not a verdict on who was “right.”
Long “myth busting” post, step-by-step blackout instructions, livestock laundry lists, and a few joke answers — classic algae thread energy.
Sharp split on whether SAE / Amanos / Otos eat living BBA; hydrogen peroxide vs liquid-carbon spot dosing; blackout as fix vs pause.
Most converged on BBA as a symptom: chase lighting, nutrients, flow, CO2 balance (where applicable), and maintenance — not a single critter purchase.
How we scored it: Qualitative estimates (engagement, disagreement, overlap), not a formula on raw reply counts.
Answers rolled into five bands
Percentages are approximate share of distinct takes in the thread.
Shorter photoperiod, more/better water changes, rinse sponges, prune leaves; BBA “loves mulm” 32%
Corydoras, snails (nerite / mystery / ramshorn), Amano or Neocaridina shrimp, Otocinclus, Kuhli loaches, bristlenose — tank-size dependent 28%
Siamese algae eaters and panda garra praised and disputed; mollies/platies “nibble” for some; several said nothing eats healthy BBA fast enough 14%
Excel-style liquid carbon with syringe; 3% H2O2 warnings; full blackout protocol vs “it comes back”; out-compete with more plants / CO2 20%
Gravel vac + bucket as “crew”; reminders that scavengers don’t replace husbandry 6%
Where it got argumentative
- SAE / Amano / Oto on BBA: success stories vs “won’t touch it until it’s dead” and failed-SAE anecdotes.
- Blackout: detailed multi-day recipe vs claims it only weakens algae temporarily if causes stay the same.
- H2O2: effective for some, risky for sensitive bottom fish and shrimp if overdosed or if causes aren’t fixed.
- Treat the thread as: diagnose why BBA wins in your tank, then use livestock as helpers — not a single-product cure.
- Our cleanup crew guide and Siamese algae eater guide go deeper on species fit (the thread even linked them).
- For planted-tank context, see easy plants digest and too many plants.
Note: Crowd threads mix experience levels. Algae chemistry and product dosing vary by tank; follow label directions and species-specific safety. This page summarizes what people said, not veterinary advice.
