    umm i guess i need major help. COPPER question

    I would highly recommend CupriSorb. Run it like carbon in a filter bag. You can also use Poly Filter. It is a brand of filter pad that will turn blue as it takes copper out of your water. I made a bad mistake early on in my tank by using a brass fitting in some of my plumbing setup. Since...

    180g setup questions

    I believe you need to run water thru your UV at slower rates for it to be effective.

    Water Quality / Nitrate Question

    I have about 90lbs of live rock and 40lbs of live sand in my 90g FOWLR. I recently noticed a few aptasia anemones growing in my tank on my live rock yet my nitrate test kit says my nitrate is at 30-40ppm...is this possible or is my test kit likely wrong? I thought anemones needed great water...

    Live Rock turning white

    You might need to raise your magnesium level slightly in order to get your calcium in the 400-450ppm range. I have head several people say that this range is ideal for coralline. In this case though, I would say most of it has to do with the change in lighting.

    Advice for sump design

    Is the DSB necessary? I am thinking of doing something similar and I was hoping that the macroalgae would be enough to get nitrates down to zero (or at least under 10ppm). I also have a question on lighting. I have a little coralife fixture that has 2 9W 6700K power compacts in it. Will this be...

    Shrimp and Crabs

    Anyone ever have problems with Emerlad Crabs and Cleaner Shrimp co-existing in the same tank? Have a 90g FOWLR. Just put an order from saltwaterfish.com and qualified for a free item. I added 3 emerald crabs and didn't think about compatability with the shrimp on the same order. Let me know asap...

    how do you reduce your calcium mine is over 520

    I am no pro but have read in several places that you should not change salt mixes unless you absolutely have to...especially using three different ones

    how do you reduce your calcium mine is over 520

    Just saw your new post. I think by raising your dKH, your calcium will lower as well...they are all connected...pH, calcium and alkalinity.

    how do you reduce your calcium mine is over 520

    Ideal range is 400-450 ppm. Unless your tank is percipitating (looks like it's snowing in the water) I don't think there is any danger to having your calcium level where it is but I am no expert

    Help!

    Ok, tested the water...copper is .15mg/L...we have found the problem. I bought a Poly Filter pad and some carbon. I did a 20% water change and now plan to keep both the pad and the carbon in for a few days and test again. This pad is supposed to be used to take medications out of your water and...

    I removed the brass check valve tonight and am heading to get a copper test kit tomorrow. I will post the test results then.

    Help!

    Ok will do. If I find there is copper in the water, how do I get it out? That kills inverts correct? Is there like a copper sponge or something? Will carbon take it out? I was thinking the best way to test the water once I think I have it fixed is to buy a snail or two...I really don't want to...

    Help!

    I have a protein skimmer...forgot to mention it. I think there is something in the water that is causing these problems. I was sitting on the floor looking up towards the light and noticed something on the surface of the water...not a film but a little cloudiness or something...

    Help!

    Another thing...I used RO/DI water to fill the tank and I can tell the coralline algea is starting to spread...something that only happens if your water quality is good right?
