Not to start a war but before I posted here I also posted on RC and got almost the opposite answer. This is what I got from RC "The Advance 71A3592 ballast is a Constant Wattage Autotransformer (CWA) 250-watt mercury vapor (ANSI H37) ballast. It will not operate metal halide lamps properly. That...

Advance 71A3592 250W Magnetic Ballast. Will it fire a 14K Hamilton Bulb? TIA

Would you consider shipping?

Green coraline usually means low light. My coraline grows all over my rocks but I have yet to see it take over my glass. I also think my salt has something to do with it. I used to keep a nano using instant ocean and my coraline was on the glass within 3 months now I have a larger reef using...

Two overflows? one for the sump and one for the frag tank? isint that gonna be a little unsightly? What other options do I have to getting it plumbed? What do others do as far as this if they have both a sump/fuge and a prop tank?

ellisz thats correct I have a HOB overflow supplying my sump and a hodemade overflow supplying the frag tank.

You know I also think this has to do with how the utube is set up. I made a quick paint drawing of it

I understand this now but my problem is I also have a real HOB overflow for my sump. If i throttle the return line down from the frag tank I will end up just empting my sump first. Wouldnt this effect the pvc u tube i made causing the frag tank to overflow until the sump was empty?

The frag tank is a small 10G with a little over 5 watts per gallon of PC lighting which im using to keep some softies.

Okay, but lets say my pump is weaker? do I leave the return all the way open and than cut the drain down with the valve? I mean i've had both a half way and fooled with both and cannot for the life of me get this to level off. do I A. leave the drain all the way open and fool with the return...

I am not quite following you. If i leave the drain all the way open, won't the frag tank overflow?

So what you are saying is that I should open the ball valve on the drain line all the way? wouldn't this cause the frag tank to overflow due to the pump not being able to carry the water back in fast enough? The pipes are 3/4 inches wide tia

I don't know where to begin. Maybe there is an easy solve for this, maybe not. I have a frag tank under my main that is plumbed to the main with pvc. gravity pulls the water down from a homemade utube (2 90 degree elbows) made of pvc and the return is put back into the tank using a pump and the...

after reading up on them I have found out the same exact thing, they spread like weeds and do so with a strong current. I actually found a pic of some that got a bit out of hand. Thought you all might find it interesting.

Last week I picked up a 2X2 piece of green star polyps from a local hobbyist around here. The pieces as well as the rest he gave me are doing great my question is in anyones experience who owns them. How fast do they grow? Should I propagate to make more or let me spread on their own?

Hyposalinity is when you adjust the salinity to below NSW. Usually 1.009 I would not recommend this if you do not have a refractometer. Swing arms are not very reliable when it comes to keeping a specific salinity like that. Too high and the ich will not die and too low and it could effect the...

If the fish just got over ich I hope you are treating all of your fish with either a copper solution or hyposalinity. Ich does not go away on its own, it must be treated and the main should be left fallow for 6 weeks. This could be the reason your tang is not eating. The ich is still very much...

ANYONE? I know this section is usually dead but someone has to share the sw hobby with me here on LI.

I have no scleractinian which is a plus. And as far as snails I have not seen many deaths in fact I have seen a lot of baby snails in the tank due to reproducing. So once my oceanic bucket is empty im going to switch to a different salt and just suppliment both CA and ALK by dripping kalk or...

I used IO for a little while than switched over to oceanic. I understand the whole "small water changes over a period of time" as to not cause shock to any of the fish, inverts or corals. Thanks though

Im going to switch my salt once this bucket is done with. I dare not ask what salt to switch to since I know how many different opinions everyone has. But I guess i'll move back to IO and take it from there.

Hey np thats what were here for.

idk about the first one you said just for the fact that I do not thing it has a membrane. I could be wrong but I dont see one. Your not going to be emptying the tank and starting over. So I would suggest something along the lines of the one I sent you or possibly the same model but the 65 GPD...

That is okay but for the price you can find better. I'm sure you dont need to be making 200 GPD and thats pretty much what your paying for. If your not into the whole ebay purchasing you can do something like this http://www.marinedepot.com/md_viewItem.asp?idproduct=KM1431 I do not know the size...
