I ordered 30 snails from Cali. Some did not make it. Took out the ones I could but some I could not find . It started hair algea . I went to vibrant for help! After vibrant red slim then dinos the kind that break up in the water column. Any way started dosing 3% peroxide at 1 ml per 5 gallons dat 3 dinos are almost gone . Will continue for full 7 days only running lights to feed maybe2 hours a day. After the 7th day I am going to dose Dr. Tims eco balance start slow and come off slow. Will keep you posted.
