Hello, I am wondering if anyone has experience using this brand of all-in-one fertilizer. I've been using it for about 5-6 weeks at the recommended dosage for a high light tank (3x per week with 50% water change) and I am having algae problems. I want to keep using the present dosage since my plants aren't thriving. I believe I have all other parameters optimized (light duration, CO2, water parameters, etc). Thanks!
