Another little thrill in the aquarium. Last friday, I added Mg to both tanks. Came back into the room about half an hour later, and for a moment I was horrified, thought my subwassertang had some disease because I saw yellow spots all over it.
that time it was right after I added Mg too.
Which is starting to feel a little frustrating. I have pretty hard water- I shouldn't have to add more Ca and Mg- but I think what's happening is the substrate is stripping it out of the water. So maybe that was a poor choice to use safe-t-sorb. Come to the point where I think I don't want to be adding fertilizers to the water every week, even though it is a minimal amount I do compared to some people. I'd rather have the substrate feeding the plants and fish waste adding what little that lacks- a Walstad type setup or a dirted tank... and since from what little I've read those type of aquariums go further between water changes, maybe I could do bi-weekly maintenance- which would make it easier to have a larger aquarium or two- because I am still dreaming of angelfish someday but realizing even this aquarium is too small for them to be happy- seeing how my bettas have been so much more comfortable in a tenner than a 1 gal bowl or 3 gal tank...
Always planning more for the future.
