Megan Abraham –
Easyroti 250 is very effective for maintaining a steady rotifer population. The algae mix is balanced and easy to mix into the culture. I’ve been using it for two weeks and the rotifer numbers are consistent every day. The instructions are clear and the culture setup is simple.
Nicholas Thomson –
Works well with my existing setup. The 80/20 mix of Nannochloropsis and Tetraselmis supports good growth. I noticed a slight drop in density after 4 days, but it recovered quickly with daily feeding. The recommended density range is accurate and easy to follow.
Chloe Bailey –
Highly satisfied with the performance. The rotifers grow steadily and the culture remains stable even in fluctuating water conditions. The 5-day cycle is reliable and the dosage is easy to measure. No issues with algae clumping or decay.
