Used it on couple.old tanks and was ok I guess. Real test was against cyano where I used it at the loading dosage recommendations and it did help with cyano outbreak I had years back.
It worked for me to reseed bacteria in an old established tank with high nitrates. I dosed daily as directed for about 3 weeks along with weekly water changes and it slowly brought my nitrates down from 37 to 8. I’m switching to the weekly dose to maintain. Will continue to test for Nitrates to see if this will maintain it under 10 where I’m happy. My phosphates didn’t really lower though. Still around .25 so continuing PhosphateRX and RowaPhos to bring down phosphates to under .1
Yup. I've used it to seed a few new aquariums/dry rock. Did great. They have newer version that's super concentrated I've used too. I highly recommend it.
