Also for people who grow lots of macro, it will absorb some alk too.

So just to be clear, is the proper DKH level 7-8 for an ULNS?

If I am not dosing vodka, bio pellets etc. should I aim for a higher range for DKH?

Is there a best method to dosing ( 2 part with doser,kalk,calcium reactor)?

I've have learned very much from this thread. Thanks to all who contributed.

I have run my alk at 8 with just a DSB, also when carbon dosing, and also when using GFO. So I think that 7-8 would be fine with a variety of methods that you choose. I don't keep it at 7 mainly because if something were to happen and my dosing is off or the needs of the tank change, the alk can fall lower than I would like without me knowing.

Dose any way you want, the method doesn't matter as long as you can keep up with the demands and keep the tank stable.

I am having a hell of a time with ALK lately. One small dip in ALK burns the coral tips, they stop their growth, ALK consumption decreases, and the alk fluctuates the other direction.

What a pain in the neck. I am watching months of coral growth die off... hopefully I can get it under control ASAP.

Original issue was the effluent line of the CARX became clogged and since it was plumbed into the skimmer intake, I couldnt see it until ALK had already dipped.

If I can figure out how to get the damn CARX effluent to keep a steady drip rate over a long time period, I'll be in much better shape.

What are you using to control your effluent? My Reactor has an small needle gate valve and is able to keep the flow very steady.

This is a great thread! I have just finished reading this entire thread. My salt & tank are running at 10 dKH and have been thinking about letting my Alk drop to 9 and then balance everything there rather than 10

The best way to keep a steady drip over time is to use a peristaltic pump which pulls the water from the calcium reactor (much better than pushing the water into it). However, such a pump must work 24 h a day, 7 days a week. Just a few peristaltic pumps are designed for continuous work, and they are not cheap. The cheapest option I have found is to use two (not the expensive Masterflex) alternating in periods of two hours. In that way you prevent them from going bad and start doing noises.

I was worried about a peristaltic pump, that it may burn out with constant use, then I looked at the ones meant to run constantly, and they have some hefty price tags. What I am shooting for is to raise the reactor pH so that the effluent is less concentrated, and increase it's flow rate a bunch. This makes the needle valves less likely to plug, since the fluid is flowing through a larger opening.

JB to answer your question I am using a special custom 45 degree gate valve that reef dynamics sells with their calcium reactors. It works well at higher flow rates (what I am doing now), but if you want a slower, or even a steady drip, it plugs over the course of a day.

Let's talk about Alkalinity, Calcium and Magnesium in an SPS Tank

I have been thinking to use my Jebao DP-4 ( bought for a while have not using it yet) , all the 4 pumps hooked together pulling the water out from my calcium reactor , I have to run 15 ml / min or 900 ml / hour and or 21,600 ml per 24 hours , so it is impossible for a single pump of this cheap chinese dosing pump to do the Job but if I run 4 pumps alternately for this purposes perhaps It will somehow lengthening the life span and giving me to save money to buy a expensive one (may be 5 years later? I doubt it hahaha) . Now I am figuring how much ml per "X"mins for this 4 pumps to runs simultaneously in a day ??? I am not good in math , any math genius help me out on this ?

My BRS pump (50 ml/min, which I don't think they have anymore) has been dosing kalk for 4 years now, and has never clogged. The outlet is about 2 inches above the water, and drops down into it.

It is not very quiet, however.

Mine has been running about 4 years aswell. I did decide to replace the hoses going in and out it. Then after looking at the hose inside it had some wear so i replaced it to.

Can you show me what kind of this BRS pump? Do you mean you run 50/ml per minutes non stop 24 hours / day , 7 days / week and whole year round ?

I figured out my tank evaporated about a gallon a day so i divided 50ml into 3785ml and that told me how many minutes i needed to run it a day

This is like ordinary dosing pump. I need to supply 21600 litrers per day to maintain my KH / CA balance. I doubt it will withstand this amount needed.

Sorry it's 21.6 liters per day

So it's about 5400 ml per pump per day , I believed with this qty , it will be much better to be handle by the cheap Chinese jebao DP 4 dosing pump.

Ah they do still sell it. The thing I like about it is that even if the silicone hose breaks, the hoses running into and out of it will not let go. So if you have the pump placed at the highest point, nothing will drain or siphon out.

awesome information guys and girls, have a quick question. Right now I'm running a kalk reactor ( two little fishies ) and a jebo doser is there any down fall in doing this or am i just making things harder for myself using 2 devices that do the same thing

For a 110g tank? 21.6L/day? That's over 5g of water/day?
You sure about this?

I have a 320g TWV system, and I probably make up 2-3g/day in ATO.
What are you going to do with that extra volume?

And I'm you enjoy Taiwan. I toured the entire island over about a month with a local/native Taiwanese woman, 20yrs ago.
Free and democratic? Probably moreso than the U.S. is these days

Nothing wrong with it, many people use two methods. I use a Ca reactor and a kalk doser.
