salinity issue

[spawn]

Thanks Danielle, but I still think the issue of increasing sal. is due to too much CA & not enough top off / ro. water going in. I've seen pics of your tank, its awesome as well, & if your only dosing in @ 100 ml per day, that's a safer ratio than mine based on the size of setups & size of corals....

Thanks I don't have a many SPS as you do though...far from that.

I don't know what to say, I have the opposite problem with salinity always getting lower due to salt creep and skimming, even if I dose 100ml of both per day.

Yeppers. I have this trouble too. If I don't don't do a waterchange (and adjust then), once a week I have to remove about a gallon and replace it with RO. Off the top of my head I think I add about 130 mL per day of calcium and about 100 mL alkalinity.

I'm going to take out some corals this coming week, in hopes that the CA demand will drop & I won't have to put so much in any more.

No suggestions but that is an awesome looking tank!

That would be a shame to remove anything from that tank.

Why not simply manually remove some water here and there and let the ATO refill it?
