Hi all,

I have a 340 gallon reef tank been up about 7 or 8 months now. I have been noticing my ca, dkh, and ph going down every week and hear kalkwasser may be a good choice for me (VERY low doses for now)

My tank has 2 drilled returns that go down to an area of my sump where I have chaeto filled with copepods. From there, the water flows to a main area which contains a big protein skimmer, and bio pellet reactor. Then the water flows to a 3rd chamber. From this third chamber a big pump pumps the water back to main tank. There is also a smaller pump that takes some water feeds through a UV filter and dumps it back to chamber 2 (middle chamber).

When I do water changes my left overflow T's off to 2 ball valves. 1 side goes out to a drain, the other side goes to the sump. When I do water changes I open the left ball valve (drain) and close the right ball valve to speed drain process.

After the water is drained out (also all day when evaporation occurs) I have a fresh water line which goes through my RO+DI to a float valve. This keeps water level in sump constant and also refills the sump after water changes. I just add salt to chamber 1 of my sump which mixes a bit before its all sent up to the tank.

I tried adding two little fishies kalkwasser stirrer in between my RO+DI and my float valve in hopes as water evaporates the float valve will open allowing water through the kalk reactor sipping kalk into the tank in very low doses. Issue I had was the pressure blew the lid off my two little fishies kalk reactor.

Is there a kalk reactor thats not $300+ that I could put between my RO+DI and float valve, or is there a fairly easy/intelligent way I could begin dosing kalk ito my system? Any thoughts/ideas are appreciated.

Thank you
 
I dont think so, your ro di is running off the pressure of the city water so when the float shuts off the flow your pressure goes up a little. I dont think these reactors are designed for high pressure buildup. A dosing pump might work better.

Thanks for the advice!

If I go the dosing route, can you recommend a reliable doser that won't break the bank? I imagine I would have some sort of mixing container that I keep the kalk mixed in and the doser sucks from the top and drips into tank at specified intervals?

I run my kalk using a litermeter stand alone pump. $130 bucks worked great it pumps ro water to my mrc kalk reactor.

you can go on u tube and do a search for dosing pumps and see videos on different pumps. I dont have any at the moment. Also do a search about the effects of using your ro di to maintain your water levels. If your float ever sticks open you will have a flood not to mention your salinity will drop. Having said that i did the same thing and had no issues. I used a kent marine float but maybe i was lucky. My tank evaporated five gallons of water a day.
 
Hey guys,

I can't make up my mind! I think a very small dose of kalk will be beneficial for my tank. I'm also lazy when it comes to tank maintenance :(

I can go drip route where I take some form of container mix up calc start a drip, but I don't want to suck out of the straw to start drip, and from what I hear the stuff that settles on bottom of mixed calc you don't want going into your tank. Are you supposed to shake this up periodically or discard it?

I can go the doser route, but them I'm looking for a storage container that has some sort of stirrer to keep it mixed up. I'd also want something where the water in it can stay full and I can just periodially add kalk powder.

Last option I could do is keep my two little fishies kalk reactor, buy a tiny pump, hook it to a timer let it run for 5 min a day (keep in mind between tank and sump I'm looking around 500 gallons of water).

Trying make up my mind best/easiest/most cost effective route to go. Any experience to share out there?
