    Help with the World of Reef chemistry

    Boomer, Through the last 8 hours I have dropped 2 liters of kalk mixed at 1.5 tsp/2 liters. It was at 8.18 about half way through the bottle last night then came down to 7.90 this morning. PH 8.05 and this is close to the end of the light cycle Mg .11 = 1335 ppm dKH .51 = 7.00 or 2.51/meq/l CA...

    Help with the World of Reef chemistry

    I will retest one more time tomorrow. Can the light cycle have much effect on the Ca or Mg testing? I did 2 tests to make sure that I am getting the same result - no goofing up somewhere along the way. Mainly on the Ca because this was first and there was such a difference. Oh no!!!! the...

    Boomer, One other thing if you say to do a water change. Since IO salt mix is slightly low for the parameters that I need to keep - shouldn't I maybe put some MG and Ca to the WC? Any other supplements? It seems that over time the net effect would be that as happened in my case the Mg and Ca...

    Thanks for the advise Steve. I hope I never will have to pull the rocks. I may just start from new base if it goes this far!!!! As for all my live stuff, fish, corals - they are all doing very well. It is just the algae seems to be hanging around waiting for another serving of lunch. Here...

    Hi Sryder, I had not put anything new in the system other that instead of only using brine shrimp(What the local shop told me to feed 2 years ago). I started adding a small pinch of J. Sprung seaweed every 3 days for the tangs. I do blow the gunk with a Mj1200 and it made a hell of a mess...

    Here are the latest test results. It seems that everything is coming together nicely. I hope it doesn't unravel the same way!!!! PH last night has dropped down to 7.88. Through the last 8 hours I have dropped 1.5 liters of kalk mixed at 1.5 tsp/2 liters. PH 7.89 and increasing still Mg .14...

    Second load of 2 liters of ro/di kalk going in and I used 185 gms Seachem MgCL2. The PH has made it to 8.08 at the end of the light sequence today. Hopefully the Mg should be about 1280 on the test tomorrow. We see

    Wow, I am sticking to the order just as you say....I have just tested the PH and it is up to 7.85 with the windows open and fan blowing. Tops are off and the PH has been slowly going up as it should. I suspect the drip of Kalk will help keep it up through the night. The corals are so open and...

    Update dKH 7.7 (Same as yesterday except the test was done at begining of light cycle) PH 7.54 (Test in morning and we'll see tonight how it looks) Mg - 1240 (It seems that my water volume is lower than I estimated - perhaps the volume or rock is more or less water in the sump than I...

    Help with the World of Reef chemistry

    Here I go, the house is central heat/air cond. It does have a fresh air cycle that I will increase also and I will get the window open to see if that helps. Another thing is there are covers (Acrylic) that are over the holes on the top of the tank. This really restricts the surface contact...

    2.5 cups of crap ie, algae mud etc from bare bottom under rocks Tank looks good after getting the true Ph and Eff readings. Wait or dose? Total change 21 gallons and room is well vented.

    Thanks, I will get the water processed and set tonight and then I can get a change done tomorrow afternoon. I hope that will be enough time to let the new water stabilize. Thanks for the articles and I will get back here with an update soon. About how long should I wait before retests?

    Help with the World of Reef chemistry

    Boomer, thanks so much. I am going to get right on it. It seems the lack of water changes proves the nitrates are an issue. (As if nobody ever had thought of that right!!!) I have adjusted the reactor to get the eff. up. I will test that tonight to see how the changes are working. As for...
