alk pretty high

[Big_Pun]

so after to diff test my alk is at 10dkh(10 on API, 10.36 with Hanna checker). pretty sure it's due to Kalk, also cal was at 428. so I guess alk is over saturating out the cal???? any tips to lower alk.... maybe adjust my reactor run less Kalk in it.

I think you can add muriatic or hydrochloric acid to lower it, but I wouldn't do it if it were my tank. Best bet is just water changes and slowly lower it. Yeah, it could be kalk. I'd run less kalk as you said. Be careful with the kalk, you can crash your tank with it. Especially if you're adding it via ATO.

i guess MH or no MH my tank tops off the same it really hasnt dropped. i may also turn the mixing pump from 6 times a day to 3 times a day.

How are your corals looking?

all coral doing ok... I took reactor off line for moment. so as I tinkered with stuff as I've been doing I figured why I went theough a few 3 gallons in two days. I had been adjusting flow in sump turning ball valves and also messing with skimmer so this caused the sump level
to drop. to add to it I messed with both my reactors also so topping off reactors with water caused water level fluctuations again more Kalk top off... I'll just top off fresh for 3 days then test

Just turn off the reactor and use plain make up water for a few days.
