Maintaining Alkalinity

[Baldy]

I have only 2 true percs, 1 chromis and 1 foxface, so bioload is small. As far as nitrates, I have npx bioplastics in a reactor. Its been keeping my nitrates and phosphates at 0. so I think I might try that.

And that is a really good way to explain the relationship between calc and alk. If I knew any other reefers, id definitely use that one

Hang on a minute! Are you intending to add coral? If you have a fish only tank, and don't plan on adding coral...just switch your salt to Instant Ocean and maintain your water changes and don't worry about balancing your calcium/alkalinity levels ....for a fish only it is not so critical.

My alkalinity is always low and I never have a problem. It's been like that for 14 months and I have a mixed reef with sps, lps and soft coral. All are healthy and grown fast. My alkalinity drop sometimes around 5, usualy is around 6. sea water is around 6.5.

Here is my tank...as you can see I have quite a mix of coral. I dose for alkalinity and calcium but I keep the alkalinity around 6 anyway. I use the Bulk Reef supply soda ash sodium carbonate as it is pure and I trust it has no additive.
