Hi!

I probably should do more water changes, but they are difficult. I've been changing about 10 gallons every week or so.

Will a large water change reduce the calcium, or is the calcium level due to excess calcium in the substrate, etc?

Salt is Instant Ocean.

I've considered that the ph could be low due to inadequate ventilation, but I really have a hard time believing that, since our home is pretty good sized (2000 square feet), very open, window open at night, etc.

We are completing the build on a new hood for this tank, with several fans. If ventilation is indeed the issue, I expect this will help.

Alk is now at 4.85 meq/l. You would increase it more? Or do you mean KH? KH is 13.6.

Any way to boost the ph without raising the calcium?

How can the animals look so healthy with such a low ph?
