Can we discuss this topic, please? I use dry ferts and since I have large tanks it is easy to shake up the amounts I use in a bottle of water and just pour them in each time I dose. However, I am thinking of doing a custom micro mix and dosing smaller amounts more often, as well as contemplating adding a small high tech planted tank or two to my collection , so I am seeing the benefits of pre -mixing my ferts, especially the micros and dosing by the millilitre from there.
So, as far as preservatives go, I have heard of adding Excell, or glutaraldehyde, ascorbic acid or vitamin C, and vinegar. Are there any others and which of these are the best options?
Can we come up with proper amounts to add of each option to a given amount of pre-mix?
