Cyano Remove is a treatment product from Aqua Connect, designed specifically to combat and control cyanobacteria (also known as “cyanobacteria / cyano / red slime / blue-green algae”) in marine (reef) aquariums. The 300 g version is one of its commercial package sizes. Its formula is purportedly natural (i.e. not based on antibiotics) and intended to safely reduce or eliminate cyano growth without severely harming beneficial organisms when used correctly.

Because cyanobacteria outbreaks are common in reef systems (driven by excess nutrients, low flow, etc.), having a product like this gives hobbyists a tool to intervene when standard measures (better flow, nutrient control, water changes) are insufficient.

Mode of Action

The Cyano Remove 300g by Aqua Connect it is a “targeted ecological disruption / suppression” tool, not a brute-force chemical warfare product.

• The product works biologically rather than chemically — meaning it doesn’t “kill” with harsh antibiotics or algaecides, but rather suppresses or competes with cyanobacteria, shifting the balance in favor of more desirable microbial populations.

• It may reduce or starve cyano by altering conditions (e.g. reducing nutrients locally, interfering with cyano’s metabolism) rather than directly poisoning it. The claims say “natural” and “without antibiotics.”

• When used, the water may bleach (turn milky or whitish) for a period, which is stated as a normal effect. That suggests some of its action creates a mild turbidity or reaction as the cyanobacteria are stressed or dislodged.

• Because cyanobacteria outbreaks often correlate with elevated levels of nutrients (especially nitrates, phosphates) and low competition, the product is likely more effective when nutrient control (skimming, flow, filtration, regular water changes) is already in place.

Specifications 

• Net weight: 300 g (package content)

• Form: a powdered / granular solid (to be dissolved)

• “Natural / no antibiotics”: The marketing emphasizes that it contains no antibiotics, so as not to broadly kill microbial communities.

• Recommended dosage (acute infestation): 1–3 g per 100 liters of aquarium water, dosed daily until the cyano is visibly reduced.

• Preventative dosage: 1 g per 100 liters per week.

• Application method: Dilute the required quantity in about 1 L of aquarium water, then add the solution into a well-stirred flow area of the tank (so it disperses).

• “Whitening” effect: Expect temporary whitening / turbidity in the water — this is considered normal and part of the reaction of the product acting in the water.

• Precautions:

  • Do not overdose. Overuse may stress other organisms or shift water chemistry negatively.

  • Because the product may reduce nitrate or pH slightly during use, those parameters should be monitored.

  • If the aquarium is already extremely nutrient-poor (low feeding, low nitrate, etc.), use half the dosage to avoid pushing the system “too far.”

  • A protein skimmer should be active during use (i.e. remove dissolved organics) to help eliminate byproducts and maintain water quality.

  • It is not suitable for human consumption. Keep out of reach of children.

Usage Guidelines 

To maximize safety and effectiveness, here are recommended steps and tips for using Cyano Remove 300 g:

1. Baseline checks: Before applying, measure water parameters (nitrate, phosphate, pH, salinity, alkalinity). Make sure your filtration, skimming, and water circulation are functioning well.

2. Start conservatively: Especially for your first time or in a sensitive tank, start at the lower end of the dosage (1 g / 100 L) rather than jumping to 3 g.

3. Dilution: Dissolve the measured powder in about 1 liter of tank water (or an area with similar salinity) to ensure even distribution and avoid local overdoses.

4. Add to flow zone: Introduce the diluted solution into a part of the aquarium or sump where water flow will distribute it, rather than dumping it into a stagnant corner.

5. Daily dosing: For acute issues, dose daily, observing the tank for signs of progress (reduction in cyano patches). Continue until the visible cyanobacteria are significantly reduced or eliminated.

6. Stop / reduce when resolved: When the problem subsides, stop or reduce to maintenance dosage (1 g / 100 L per week).

7. Monitoring: Regularly track nitrate, phosphate, pH, and other relevant metrics. Be alert to sudden changes (e.g. nitrates dropping too low, pH shifts, coral stress).

8. Avoid overdosing or stacking with other treatments: Do not combine it recklessly with strong oxidizers, antibiotics, or other harsh algaecides unless you’re experienced, because interactions may stress or kill beneficial organisms.

9. Maintain good husbandry: Using the product is a remediation step, not a substitute for controlling sources of nutrients, optimizing flow, ensuring good filtration, and performing regular water changes.

10. Be cautious with sensitive organisms: If you have extremely delicate corals, anemones, or species with low tolerance to changes, monitor them carefully during treatment. In such systems, starting with half dosage is safer.

Advantages of using Cyano Remove 300g by Aqua Connect 

• Because it is advertised as a non-antibiotic, more natural approach, it may have fewer side effects on beneficial microbial populations compared to aggressive algaecides.

• Useful particularly when other preventive measures (flow, nutrient reduction) are not enough to suppress cyano.

• Flexible in dosage: can scale with level of infestation (lower for maintenance, higher for emergencies)

• The milky whitening is a known effect, so users know it is expected and not necessarily a sign of catastrophe

• Provides aquarium keepers with a tool to intervene without immediately resorting to more drastic measures.

Limitations 

• Because it does act on cyano, there is a risk that other non-target organisms (e.g. delicate bacteria, microfauna, corals) might be stressed if the dosage is too high or the tank is already on a tight balance.

• Whitening / turbidity might reduce light penetration temporarily, which could stress photosynthetic corals if severe.

• Overdosing or prolonged use may drive parameters (nitrate, phosphate, pH) downward too strongly, possibly leading to nutrient starvation or instability.

• In nutrient-poor systems (very low nitrates / phosphates), applying the full dosage might upset the balance — hence the recommendation to use half dosage in such cases.

• It is not a permanent fix: unless the root causes (excess nutrients, low flow, dead spots, organic buildup) are addressed, cyano may return after cessation of treatment.

• Some tanks may respond poorly, and interactions with other chemicals or medications may produce unexpected effects.

• Because whitening is normal, if the whitening is extreme and persistent, it might indicate overdosing or poor dispersion.
