Robert.. I forgot to mention, I already do use a Nelson reaktor for dosing kalkwasser. it´s an home made, but it works fine. The thing is when the co2 goes this high, the pH tend to drop all the way down below 8.0, and seem impossible to get above except for some minutes, after the reaktor has...

Just to let you all know.. I have found the reason for the low pH in my Tank. A friend of mine have leant me a Co2 tester, which I have set up in my living room, (same room where the tank is placed), and unfortunatly it showed exactly what I feared it would. At evening when the family has been...

Hmm okay.

Brandon, here are some pictures of the salt creep I mention from the IKS pumps. http://akvariet.terrabyte.dk/salt/page_01.htm Notice the salt creep underneath the pumps and on the brackets. If you want to see pictures of my tank, I´l soon be uploading some new ones to my site, but here are some...

The reason is mainly to try add some ekstra air to the water due to low pH (still). I may be gaining some better skimming, but I doubt it since there will still be aprox. 150gal/h going through the skimmer.

Ahh, finally something I can answer :D It sure has something to do with the fan. I have two IKS Turbo pumps in my tank. These are external pumps placed on top of the tankside. The problem is the way they´re build, it takes the air and push it out and downwards round the pump, this is due to a...

Hmm okay. So it could have an influence. The reason I ask is because I´m thinking of changing my system, to let all the water from the tank go through the skimmer, insted of the way I have it now, were the skimmer is feed from a powerhead in my sump. The only problem is, my skimmer is an Deltec...

Randy, a friend and I are just having a small debate on the nitrate matter.. We´re wondering if the size of the skimmer (or the ammount of water going through the skimmer) have any influence on the nitrate at all? My friend says it does, but I really doubt this. Greets Kim Andersen

I have thought about a second chaimber for the calcium reactor. What keeps me back is, that I have tried in a periode of more than 14 days to shut off all co2 supply to the reactor. It didn´t change the pH, but insted lowered the alk (as I suspected). This tells me, that even though I supply co2...

Rob. I have read your article. Actually I read it some weeks ago in my search for the reason, and you´r article was one of a few which lead me into the climatic carbon dioxide.. (damn, lets call it Co2, it´s easyer :o ). I do however have a friend who told me he got some sort of device to test...

Hi Gresham. As I mentioned, I have tried increasing the flow on the reactor which brought the calcium up above 500, which in my opinion would be the same as adding ekstra kalkwasser (or calcium hydroxide). I may be wrong on this, as your suggestion has been mentioned as well on our danish...

Hi Rob. That might well be the reason. I have noticed an increase in the pH when I open a window, and a critical low when we´re many people in our living room, (where the tank is placed). Unfortunaly the conditions doesn´t make it possible for me to have the windows open all time or to make an...

Hi there. I´m new to this forum, and used to use a local (danish forum), but now I´m getting rather tired of this problem, so I´ll try seek some good answers or suggestions at your place. I have a aprox. 480L reef tank at my home, which is suffering from low pH, and it seems like no matter what...
