Dump the Kalk reactor, get a Calc reacter and use Caribsea ARM media. You will not need to run the effluent through phosban or anything like that not that a phosphate remover in the sump wouldn't be useful for other reasons.

I have a Koralin 1501 reacter and the setup is fairly simple although you do need to spend some time tuning it initially. I will try and explain how it works in simple terms although I may fail...

The reacter is a large tube filled with water and the media with a pump on top. The pump takes water in from near the top of the tube and pumps it down a shaft to the bottom where it then rises up through the media. The input and output both also have an airline tube coming off of them, the input goes in the tank to bring in new water and the output tube can go in the sump. The output tube has a valve to control the flow to a drip rate, mine runs between 40 and 60 drips per minute usually.

Finally, the part that makes the thing work is a third airline tube entering the inlet side carrying CO2. You adjust the CO2 bubble rate to match your drip rate based on a formula in the instructions and it acidifies the water lowering the PH below 7.5 which allows it to disolve the calcium and other beneficial elements (the stuff is made out of coral skeletons so surprise surprise it contains the elements living corals need to make new skeletons). You can measure the PH of the drip water to make sure it is working OK, but it will be. Despite rumors to the contrary, this machine tends to stabilize the PH in a tank not lower it because if you have good aeration the excess CO2 goes into the air and the calcium and alk values in your tank are raised. In fact the my bigest beef with a Kalk system is it tends to raise PH too high and cause calcium to precipitate out, the opposite of what you want it to do.

The only tricky part is setting the bubble rate just right. Too high and excess CO2 will collect inside the reacter, too low and it is not working efficiently. Also, this is a long term stabilizing device, it will not correct Ca and Alk levels in your tank overnight or even in a couple days if they are way out of whack. It also will not work if your Kalk reactor causes even localized areas of high PH and precipitates out the Ca your trying to put in. For this reason, I would dump the Kalk device at least temporarily and use a 2 part additive to get your levels close and then let the Calc reactor maintain them. The Calc media will last 3-6 months usually and the C02 tank lasts me over a year, so once setup it is an incredibly low cost low maintenance item to run.

In short if your after stable water conditions, there is nothing better then a Calc reactor for maintaining trace elements Ca and Alk as well as PH.

I disagree with that advice. In fact, IME kalkwasser use can actually help resolve an algae problem. At the very least I'd recommend Rob continue with his kalk top-off while using the Ca reactor - they compliment each other well.

ARM will leach phosphates as will most other Ca reactor medias.

I recommend most newbies stay away from Kalk because it is way to easy to have problems. The fact that he is running it 24/7 and still has such low (and dropping) Ca levels is a major red flag that he is in fact having the problem the so many other people have also had, calcium precipitation.

Since it is not working, and there are signs he is not doing everything right with it, I think it is bad advise to tell him to continue using it for now. Yes, once everything is stable and he understands the process better, Kalk can be a great compliment to the Ca reactor, but not now.

The phosphate problem has not shown up in my tank in the first 4 years with the reactor, so I think he has time before he need to worry about it. I do think Rowaphos or Phosban in the sump is a good idea to get overall phosphate levels down, and that would be much more usefull the just running the reactor effluent through it.

There are a lot of successful reefs using Calc reactors so this is not kooky out there advice. It has been tried and proven for decades now.

I agree that CA reactors are good and almost every TOTM has one.

I think what Chris is staing is that since I have had so many problems with the tank so far, adding another piece to the puzzle could spiral the tank back where it was 2 months ago.

I think the low CA is due to Instant Ocean that has a CA of only 300 when freshly mixed. Even before I had the Kalk reactor over a year ago I had low CA using IO. The only way I was able to achieve high CA is by using Oceanic Salt that I discontinued since the magenesium was over 1700 and the CA was 550.

I have tried B-Ionic as the instructions have stated as well and the CA/Alk does NOT move.

1) Change your salt mix to something better, although none are perfect. That is part of why I do not recomend frequent water changes. If the salt mix is not right you keep throwing your tank off with every change.

I have managed to keep a reef looking good for several years without a water change but I would recommend you try larger water changes 1-3 times a year for now until you get a feel for how things in your tank react.

2) Be VERY PATIENT with the Calc reactor if you get one. It will not bring your Ca from 300 to 450 over night, it could take a couple weeks to get where you want to be. You may want to stop your tank testing for a while so you ease your frustration and not feed any urges to "do something". Just let the system run for 4-6 weeks and it will likely stabilize itself.

3) If you're confident you understand the Kalk reactor and you think that is not the reason your levels dropped, go ahead and keep using it. If you have any doubts set it aside for a little while and fus with it after you have everything else stable.

Rob, knowing you've been around the hobby for a few years I don't consider you a newbie and have every confidence that you're dosing kalk like a pro.:wink: IMO/IME there's no reason to suspect the addition of kalkwasser has anything to do with your algae problems and if anything, is helping the situation.

A stable system with enough export can handle the extra phosphate a Ca reactor will introduce. Since you, however, are trying to battle an algae problem, I think it's a bad idea to add yet another variable, and an additional source of CO2 and phosphates into your system via a Ca reactor right now.

As for how best to run the Phosban, that's a whole other debate, but running it passively in the sump is arguably not the most effective way. IIRC you already have a Phosban reactor which would be a better option.

Personally, I think Ca reactors are great and prefer to use one myself (in combination with kalkwasser, actually) - nothing kooky about that. IMO the kooky part is telling someone to stop dosing kalk and start using a Ca reactor to solve an algae problem... :wink:

At any rate, it sounds like you're on the right track. Should just be a matter of time now.

In my opinion, telling people they need to use Kalk these days is similar to the advice I got in the late 80's telling me I needed a wet dry to keep inverts. The method worked, but it turns out there were better ways. I am not the first crazy guy to think this up either, I learned it from others who were successful with Ca reacters long before I knew what one was.

FWIW, I agree with ChrisRD's advice regarding the kalk reactor. It certainly isn't contributing to your algae problems and can only help. I'd continue using it and avoid a calcium reactor for the time being. Despite what anyone may say, ALL the media used in calcium reactors, especially ARM, leach phosphates. I think this will only set you back. If the kalkwasser isn't enough to maintain your calcium and/or alkalinity, I'd suggest supplementing it with one of the balanced two-part calcium/alkalinity supplements, such as B-Ionic.

Rob,
How are things going?

In my little build off tank, things are looking much better. I've been using some of the suggestions in this and other threads. ie, 10% water change every other day, less feeding, pulling/syphoning what I can and things are looking so much better. Not all the hair is gone, but there isn't any new patches showing up either. On the 3rd change of the week, I've been doing a larger wc, 30 to 50%. It has made a world of difference.

I also agree with ChrisRD's advice here. Just makes sence. In any case it does sound like your on the right track. I run Phosban in a fluidized reactor which is way more effective then throwing a bag in the sump.

In my opinion, telling people they need to use Kalk these days is similar to the advice I got in the late 80's telling me I needed a wet dry to keep inverts. The method worked, but it turns out there were better ways.

Just b/c there has been CA rx out for a long time doesnt mean kalk is dated. It just means that there are more options. Does a CA reactor help preticipate P04? I love kalk and have used both a CA reactor, Kalkreactor and both together. If the alk is fine and you just need some additional CA there are many ways to adjust it. I like saliferts coral CA, or kent marines Turbo CA. Otherwise a bit of baking soda will adjust your ALK.

Sorry if I missed it scanning the previous posts, but when was the last time you replaced your lights? I had a HA problem like the one in your pic and after someone suggested changing my 2 year old bulbs :D the HA went bye bye. Justa thought.

My new problem is all the algae is now red hair algae.

THinking again I should have just eihgter dumped the whole tank in May or emptied the tank and got new LR.

Have you tried any of the large Mexican Turbo snails yet? If the algae is that stuff that looks like red cotton candy, they eat it IME.
