Why call tiny bugs heroes? Because they drink sunlight and eat pond trash – simple as toast. But aren’t they tricky to handle? Nah, they live everywhere already, you just give a nudge. These microbes use light as fuel, turning muck into safer stuff and even food.
Quick list, no frills:
Do they fight each other? Mostly they party together, one spits oxygen, another gulps ammonia – circle goes ‘round. Need a starter? Click BioAqua, drop it, watch smell fade. Some folks say “science jargon scares me”, but numbers whisper truth: ponds with PSB show pH steady 6.5-7.5 and fish breathe easier.
Why purple, why sulfur, why the long name? Color comes from weird pigments; “non-sulfur” means they don’t choke on sulfur yet can snack on it if forced. Funny critters, right?
How to pour? Farmers here sprinkle 5 g Aqua Health Booster per m² weekly; smell of rotten egg goes bye-bye. My own tank of tilapia? Added purple broth, day later water turned tea-red, fish kept munching, no stress – small win, big grin.
Ever ask, “Why is my koi dull brown?” Answer slaps back: missing carotenoids. Spirulina fixes that.
Will fish even taste it? They nibble quick; but go slow, above 10 % powder some carp pull funny face. Blend it with Aquaculture Yeast so smell turns bread-like. One hobbyist told me, “my goldfish went disco-red,” kind of silly phrase yet real result.
Need oxygen without paying electric bill? Chlorella pumps bubbles all day for free sun coins. In BASS, algae give O₂, partner bacteria gulp waste – team sport.
Numbers talk plain: tubular reactor loaded with Chlorella sp. GD scraped 99 % phosphate, grew 1.3 g L⁻¹ day⁻¹ biomass – pretty fat for green soup.
Table snack:
| What | Score | Proof |
|---|---|---|
| COD drop | 90 % | HRAP run with C. vulgaris |
| NH₄⁺ cut | 77 % | Same reactor |
| Biomass protein | 45 % | average cell |
Can I feed the algae back? Yup, dry cake gives CGF, fish guts heal faster. Blend with Biofloc Fish Farming pellets for circular snack – waste to feed loop, tidy idea.
Doubting Thomas in the room? Here’s raw digits.
Fish spend energy on growth not detox; farmer laughs to bank.
| Goal | What to Add | Dose | Reminder |
|---|---|---|---|
| Start-up water detox | Aqua Photosynthetic Bacteria | 10 mL / 100 L | sunny day best |
| Weekly sludge trim | Sludge Remover | 5 g / m² | stir bottom |
| Color boost koi | Spirulina meal | 1 % feed | stop at 10 % |
| Stress after rain | Anti-Stress | 3 g / m³ | dissolve first |
Why stir? Bugs hate pockets with no light; mix them kindly, they pay rent.
Shop shelf screaming – which bag wins? Use this sniff test:
I once bought a cheap bottle, label peeled in rain; bugs dead, fish sulked – lesson carved.
Will robots replace microbes? Unlikely – sun keeps shining free. Next wave? Strain cocktails custom-coded for shrimp hatchery or carp biofloc. Photosynthetic Bacteria in Aquaculture blog keeps gossip updated.
Picture this: waste broth pumped to biorefinery, spins out fish feed, bio-plastic, maybe hydrogen bubbles; pond turns emerald not brown. Sounds dreamy? Bits already live in pilot farms, so keep eyes peeled.
Photosynthetic bacteria need light to charge up. Aim for at least six bright hours daily; eight to ten is ideal. If clouds cut light, bacteria still work, only slower. In shaded ponds add low-watt LED grow bars to keep activity steady. Keep lights off at night to let fish rest.
Healthy PSB strains are probiotic, not pathogenic. Overdosing may cloud water for a day, reducing visibility but rarely causing stress. Always follow label rates, aerate well, and monitor ammonia. If fish gasp or water smells foul, perform a 20 % water change and resume with half the previous dose.
A slight jade tint is normal when feeding Spirulina powder; it fades as fish graze. Heavy green soup signals overfeeding. Cut back to 1 % of ration, run a fine mesh filter, and siphon settled clumps. Good circulation prevents surface mats and keeps water clear while color still boosts fish hue.
Keep the bottle sealed, upright, and out of direct sun. Ideal temperature is 5-20 °C—think cool pantry or refrigerator door, never freezer. Shake weekly to resuspend cells. Use within six months for peak activity; after that viability drops and you may need double the dose to achieve the same effect.
Never combine PSB with chlorinated tap water. Residual chlorine kills bacterial cells within minutes. Dechlorinate first using sodium thiosulfate, activated carbon, or 24-hour aeration. Confirm free chlorine reads 0 ppm before dosing PSB. If accidental contact occurs, discard the batch and start fresh to avoid ineffective treatment.
