    Using my own inline RO/DI water supply. If have algae means have phosphates, then how do most you pro's eliminate phosphates? Water changes to bring out algae on glass faster after each glass cleaning. Have calc reactor, skimmer, etc... What is the secret to eliminating phosphates?

    Ok, I know that Magnesium and Calcium go hand and hand, Strontium is also somehow added as well. What exactly are all the relationships with the three, how do they work together and against each other?? What levels of each are going to be most beneficial and stable in a reef tank, and if one...

    Does anyone have some advice? We have a reef tank set up, its been up for about 4 months. Can't get the calcium levels to increase. Just bought a protein skimmer seems to have fixed the nitrate levels. My mushrooms in the tank are not seeming to happy right now. I started adding just straight...

    hey all, It is finally time that I get my calcium reactor set up. Only thing is, I have never owned or operated a calcium reactor before, so I need help. Can anyone take some time and help walk me through how to set it up and get it properly set? also, I have a milwaukee pH controller...

    My PH is always up high. 8.8 usually. (Source is like 7.8 ???) Should I be trying to lower this? I add calcium, purple up sometimes, but no PH/ALK buffer of any kind. These typically raise PH or ALK, don't they? My ALK is usually high too. About 9-10 range now. Was staying at about 11-11.5...

    Hi everyone, this is my first thread ever. So help me god if my grammer and proper ettiqutte is wack! Anyway I just switched over to RO water to do top off's in my 90 gal. I tested the Ph just to see what was up and it was at 9. I am wondering if I am going to need to use Ph down or something...

    Seems like everytime i do a water change with my top off water (distilled) it effects my alkalinity, should i buffer my top off water to get it to a good alk, i think the top off is 80mg/l but my tank water is like 200-300mg/l i think or meg/l or whatever just wondered if anyone else does...

    So I was thinking... The Ksp (kinetic solubility constant)f or calcium hydroxide (kalk). is 5.5x10^-6 at room temperature 22-25C. Which means that a saturated solution contains 0.028 moles/liter. This is converted to 1.122g/l taking the mass of calcium to be 40.078 g/mole. There are 3.785...

    "IO is great on alkalinity buffer, but low on calcium-Oceanic is high in calcium, but lower in alk buffer,,,therefore a mix will balance the mix." Has anyone ever heard this? Sounds logical...

    hello I recently setup an RO DI unit in my new house, and wanted to know what the pH of the purified water of your systems was? the water going in has a pH of 7.6... and my water coming out was higher than this. my LFS thought that it should go down after the RO DI system not up, so I thought I...

    Explain this to me. Is it Alkalinity and PH that control that amount of calcium? Or is is alkalinity and calcium that control the PH amount? Or is is PH and Calcium that control the alkalinity amount? I am trying to find a freaking buffer that I can add EVERY day or atleast 4 times a week that...

    Good Morning, After having my LR in the tank for 4 weeks, I purchased a coral beauty, Purcula Clown and a Firefish. I bought them on Sat morning and on Sun the Firefish had died, I removed it as soon as I found it but the Coral had been eating on it. Tues AM the Coral had white strings hanging...

    I have been strictly dosing kalk only. I've heard that there may possibly be left over hydroxide ions. Are there any buffers and/or additives I can use to help "pair" these off? Also, I was wondering if anyone has used SeaLab No28 (someone suggested it)? Thanks........

    I need major help people! I've just performed my first water change and it just made my tank worse. I changed it because it's the first time I've done it since I started about 4 months ago. I have a 90 gallon reef ready with a g3 skimmer, Mag 1200 pump, 2 metal hallides 150 watts each. Ok, I...

    I put a hold on a Mandarin Dragonet from the Petland near Perimeter on Thursday night. To make sure everything was okay to add the fish, I tested all of my water parameters and they turned out fine. So on Friday I bought the fish. I acclimated it by letting the bag sit in the tank for about 15...
