I have been noticing my Mag. levels dropping lately and after checking on my new water change levels noticed that the readings are very low from IO mix ( 900 - 1000 ) I have always supplemented the calcium in my mix to raise it and with the offset in price have found it worthwhile. But now with even more to add , I'm wondering if it is worth switching brands.
Has anyone had any luck with the Deltec Brand? At almost double cost I would want it to be near perfect levels each and every time I do a water change.
Any other brands that you have found very reliable?
