I can't even find that NL power supply on the NL website....HERE.

I found a power supply that would work, but can't seem to find a US supplier, and have seen reference to the fact that these power supplies are extremely expensive. The Inventronics EUC-096S070DV(SV) would work as a replacement for your fixture....found HERE. I'll keep looking because I know...

James, I've looked for them is the past and never found anything. I'd suggest looking at Mouser HERE. What's important is Constant Current of 630 mA (or there about), and dimmable voltage of 70-120V on the Output side. Now Apollo eventually switched over to Meanwell drivers (as seen in...

Wow! That must have been a long time ago because we now refer to Julian in the past tense....Julian Sprung! :eek::D But then again, he probably had hair back then. Welcome to the NJRC!

I didn't know that about Banggai.....makes me feel a little better over the loss of the ones I had a couple years ago. I now have pajamas, and wonder if they are short lived as well??? They are easily more than 2 years old now.....probably more like 3 - 4.

I think it's stability. If the water is always at temperature X, and really never fluctuates, then you're fine. However, if you see swings of 4, 5, 6 degrees or more....now you have problems. I know the same thing can happen with nitrates. If you slowly build up nitrates, fish and some...

I think you have a couple options, but without question, you need to purchase your very own RO/DI unit. With that large a tank, it will pay for itself fairly quickly. Options (that quickly come to mind): 1. What @art13 suggested above....pump out, pump in. 2. Automate with a dual head pump...

Agree with @Mark_C , using a large bead of silicone if doing acrylic to glass. Don't think pretty, think function, and a thick bead will help hold that baffle. Also, let the silicone cure for as long as you can wait.....three day minimum for me.

HERE's a nice little article from Dr. Farley about water parameters. As far as your zoa's are concerned, they don't consume alk, calc and mag....they are soft corals with no calcified skeleton.

I thought this would have gone quick......last chance before I post on other sites. It's a nice little skimmer.

Here's my story.....I've lived in this house for 36 years. When we have a power outage, before I can get up off my butt to find a flashlight, the power has come back on. I don't know if they re-route, or what they do, but we just don't get power outages......until. A couple months before...

I don't care if I lived in an apartment.....and they had a rule against generators. If I own a reef tank, I'm having a generator....even if it's a small one from Harbor Freight. I'll put it out on my patio/deck and run this thing until the power comes back on. Either that, of have the...

You'll only need the 7 and 10. Good laboratory practice tells me I shouldn't stick the probe directly into the solution bottles. Pour a small quantity into a test tube; rinse the probe in RO/DI and then stick your probe into this test tube....calibrate....and then dump that solution down...

I have had issues with buckets, even with the lid clicked all the way closed.....that's why I prefer the bags in the 200 gallon boxes. Even resealing the bucket, I've had a crust form on the surface when humidity was high. So here's what I do with the bags. I roll/fold the bag closed...

A couple points about pH probes: 1. They must ALWAYS remain wet....in some solution. 2. They can never, ever be completely submerged. If saltwater (or any other liquid) gets into the probe, it's done! c. If the probe becomes sluggish, they can be cleaned by soaking in vinegar overnight, and...

Marcus, here's a full view shot. The water comes from the RO unit (from the membrane exit) to the valve. Right now the valve is positioned to run the water to waste (I collect my waste water in the 55 gallon drum). Once TDS out of the membrane stabilized (usually around 1 or 2...

I've purchase salt from Dr. Foster's and Smith.....RC is 49.99 for a 200 gallon box, free shipping. Your mailman will love you. :rolleyes: I get the plain IO for 39.99 a 200 gallon box.

I'd be surprised if the pH is actually 7.5. What are you using to maintain ALK. The best for keeping pH up is kalkwasser.....and then supplement with two part when the kalkwasser can't keep up with demand.

First off, I would never use tap water......RO/DI or purchase water if need be. The "snow" you are seeing is precipitated carbonate that will not go back into solution. Moisture must have gotten to the salt. I have seen yellow bags with RC that has been exposed to moisture....but you also...

The Starry Blenny was one of my favorite fish....they have such a personality. Not only that, they can turn their stars on and off....but not sure what causes this....being relaxed or stressed. My guy use to perch and watch me walk around the fish room. I had to watch when I turned off...
