This only to say top randy that the iodine article is fantastic. We need such scientific way to deal with our hobby. I am tired of reading: give two drops of XXXXX , corals will double... Gooooooood work Randy! Hope that the Xenia experiments will give us the answer to a question that I am...

Excuse me, I've posted in an horrible english. But I've understand your answer *I belive*, and was what I wanted to know! The second chamber isn't so effective, but can lead to a little improvement in ph, and maybe more Ca and Kh in the tank water. Is so? If yes, I've finally understood! More...

"The other question is... making the effluent of a co2 Ca reactor running in SOMETHING (i've read Ca carbonate..) this can lead to a Co2 adsorbition and so to a higher ph? What you suggest? Runnign it over more calcium carbonate media is supposed to help raise the pH, but those attempts are...

Thanks Randy Holmes!!! :D

Many thanks for your BIG help Randy!!! I've found in Italy a product that should be MAINLY dolomite rock crushed... but when I asked to the manufacture, they answered that the composition of the product (intended for marine aquarium) is: CaO) 40,4 % (MgO) 25,8 % (FeO3) + (Al2O3) 0,6 % (CO2 +...

I've read that the ph of the water is VERY important for the results in our tests (example Salifert). So, when I measure the Ca and the Mg in the effluent water of my Ca- Co2 reactor, I can have errors? Many thanks, Marco

I post also here, for Randy! (many thanks in advance!) I've a Ca-Co2 reactor. As usual, I am worried about the low ph in the morning (7,8-8) despite using also a Kwasser reactor. The question is... making the effluent running in SOMETHING (i've read Ca carbonate..) this can lead to a Co2...

I've read a lot about miracle mud, and from the analisis I've understood that is very enriched in Fe. Maybe, all the muds success (Caribsea-miracle mud- seachem- Kent Marine) and the reason why they work well is the Fe binded to the substrate, so caulerpa can get it but the algae in the tank...

I've a new Knop C reactor in my refugium. The reactor is made with the IN water down and the OUT up, out of the surface of my refugium. The reactor is nearly all under water. The "in" takes water by itself, there is no pump putting water in the reactor itself, because my retailer said me that...

Nice reply Eric! I read the Sprung article and your answer with a lot of interest. Hope that Sprung will answer! More, another time I ask to Sprung: what kind of Fe and manganese supplement you are using?

I've read the interesting article of J.Sprung about Goniopora, I hope he is right and is fe-manganese the solution to Goniopora problem! I would like to know how much Fe and Manganese he suggest to add, and the name of a Manganese product, or how to add it. Thanks, Marco

Because I wish to raise the Ca in my aquarium with the use of KW (i've only a Nielsen Reactor, not a Ca reactor), I am thinking to solutions. Because I've read from J.Sprung that is possibile to mix CaOh also with salt water, not only RO water, I've thought that I can make a little pump flowing...

First, many many thanks for the answers. Now... the situation in my aquarium become every day more strange... The story: 1/8/2002 new tank. End of august beginning of the population. Half september pink calcareus algae everywhere and the little acroporas growing very fast. Kh 8, Ca 450 *only KW...

Is possibile that 15 acroporas (growing well) *from 1 to 4 inches long* can reduce the KH so, that a full bottle 16 oz Kent kh+ used in 10 days isn't able to raise it? Thanks, Marco

I own a full Berlinese 300 lt. tank. Is 3 month old, and is going well. I have a kalkwasser reactor, filled with 3 spoons every week of CaOh. All values were OK, also if only in this days I've a fully understand and operative reactor ( Ca was OK before, because I've mainly little acro frags)...

Waiting an answer to my previous topic, I would like to ask to J.Sprung if *and where I can read something about in the net* he did tests for his "marine snow" as SPS food. Thanks, Marco

I have a new tank, 300 liters. Is a Berlinese, with heavy skimming, live rocks, medium sand bed. The tank is 2 month and half going. I have only two fishes, both eat algae. The corals are growing FAST, think that in two weeks two "flowers" of tubipora musica became eleven. I have also SPS...
