    hello guys. I am having a problem with calcium. no matter what i do, my calcium reads over 500. I tried water changes and cant seem to get it down. I try to add more DKH (which reads 7.4 at the moment) but for some reason I have an imbalance. If I add kalkwasser, will that balance the 2 of them...

    Hi, I have a 93 corner heavily stocked with SPS. Recently, I added a DP4 dosing pump to keep up with tank demands on Cal/Alk and Mag and after about a month it seems to be working using ESV B-Ionic 2 part and Mag. Cal ~400, Alk ~9dkh and Mag ~1350 (elos). My dosing volumes have been very heavy...

    I'm going to start dripping kalk into my 5.5 gallon (Fluval Spec V) reef tank to help stabilize my calcium and pH (I have low pH problems also) I can't add kalk through my ATO because it would end up dumping in too much at one time so I've already set up a kalk dripper from a 1 gallon milk jug...

    Im starting to have low alk even with weekly water changes. My calcium stays at 460 my I already do dose mag. I checked my alk yesterday and it was at 6. Should I bring the alk up with a alk supplement and use kalk or should I start using a 2 part. I have a 75 gallon 40 gallon sump. I have...

    I am using a gravity drip to dose kalk from a one gallon jug. I am doing about 3 drips every 10 seconds to replace evaporated water. From everything I read it should be at a faster drip rate so I should maybe try increasing evaporation. Also, I started with one teaspoon/gallon and thinking of...

    Hey everyone. So I have decided to do another DIY project. I want to make up a Kalk reactor. I have seen some basic builds, and some more complex builds. I want to land somewhere in the middle :) I plan on doing a build exactly like this one...

    I took my baseline yesterday and wondering how often I should test to find out how much depletion there is so I can calculate how much kalk to dose? Daily... weekly... before my next water change?

    I recently stopped adding kalk to my ATO. I didn't like the all the mess in my reservoir and the buildup on the pump. Anyhow a week or two after cleaning out reservoir and using only RODI I have this big cyano outbreak. Is there anyway this could be related? Its the only thing that I have...

    Hey all, Quick question from peeps in the know. I have a 12 gal mixed nano reef, est for a year, all going well. No major swings, all stable. My question is, currently I perform 50% water changes per week, and I'm also dosing kalk +2 through my ATO. With my weekly water changes, I'm also...

    I came home last night to my entire reservoir being cloudy with kalk and my Two Little Fishies Kalk Stirrer not being able to hold water in the chamber when the pump turns off. This in turn leads me to believe the check valve has failed. It's a shame being as all the equipment is less than two...

    So im thinking about starting to dose kalk. into my 75 gal. mixed reef tank. I have approx. a 15gal sump. with a tunze ato feeding off an 8 gal rodi reservoir. I really don't want to put the kalk into the reservoir, I don't like the nasty soup it makes in there, and have also heard it is...

    Howdy all. I use 000TDS RO/DI in a 7g gravity fed line float to a float style valve in my sump. I know that kalk can be added at a diluted saturation to affect Ph./Ca./DKH. but what are the "ideal" parameters for the ATO water? is there an "ideal" Ph./DKH? or just go by the results in the system...

    Hey everyone - quick question - I just upgraded my lights and that took a chunk of dough - so I'm still kicking it old school on the kalk (can't afford the Kalk reactor and controller set up I'm aiming for yet). I had been just mixing it in my ATO, but the precipitate makes a mess and creates...
