Reef Central Online Community - View Single Post - Might start dosing... calcium slightly low

ozorowsky · 03/07/2018, 06:49 AM

Hi all,

I have a 340 gallon aquarium with about 20 fish and mostly soft corals like hammer torch etc.

My sump is about 150 gallons with bio pellet reactor, large euro reef skimmer, chaeto, uv light. I hardly ever do water changes.

I noticed my dkh sitting around 9 per api test while my calcium sitting serious 400. Ph around 8.1, everything else within tolerance.

I purchased reef code a brought my calcium up top about 420 but it is not seeming to go higher dkh still around 9.

What is the most cost effective way to dose to keep up with calcium/ dkh? I was reading about using kalkwasser? Any thoughts on that?

Thanks all trying to steer things in right direction.
