    Micro Bubbles!

    When you plumbed the hook over the side of the sump, did you incorporate a way to prime the pump? It's more than likely that the pump has air built up in the impeller chamber and is cavitating. Another possibility is a micro-leak where your tubing meets the hose barbs pulling in air, yet not...

    Nickle Plated Magnets

    I don't know how well nickel holds up in saltwater, but I wouldn't trust putting bare metal into saltwater for long-term. Plus, I know that nickel is often used in a copper-nickel alloy, and I would be afraid of copper contamination if this were the case of these magnets. The magnets used for...

    Help choosing lights

    Comparing the 400W PFO Pulse start ballast to a 250W DIY Probe start ballast is like comparing apples to oranges. At 400W, a pulse start ballast would limit you to only a few bulbs; I would recommend either Probe start or HQI at that wattage. Personally, I run 3x400W PFO probe start ballasts...

    Some new stuff from my 125

    Your Sebae anemone looks great and healthy! It's sickening to see those anemones bleached out and ghost white at LFSs. I like the colors on your Favia as well!

    question for experts.

    If there's no water on the floor, it's definately evaporation! When I had my 65g w/ 20g sump setup, it would evaporate a good 3 gallons per day.

    to much light????

    That's not too much light at all. In fact, you would probably need at least 3x250W MH if you were planning an all-SPS or clam tank. Depending on the color of the MH bulbs, they would need to be replaced anywhere from 8-12 months (high-K bulbs need to be replaced sooner than 6,500K or 10,000K...

    Coral Banded Shrimp - SAFE or NOT SAFE

    They are extremely territorial if anything gets to close (the shrimp will take a nasty swipe with it's pinchers), but are otherwise peaceful and go about their business scavengering around the tank.

    Lumenarc?

    It all depends on what pendant/reflector is being used for the 150W HQI to make an adequate comparison. Plus, a similar colored bulb needs to be compared as well (a 20,000K bulb isn't going to be near as bright as a 10,000K bulb; we need to compare apples to apples). HQI bulbs aren't any...

    What Kind Of Protein Skimmer Should I Get?

    Coralife has a new line of protein skimmers called Super Skimmers that are getting rave reviews. They can be used as either HOB or insump skimmers, and the model rated up to 65 gallons can be had for less than $100.

    is an RS5-3 too much for a 55g tank?

    The Euro Reef 5-3 is about the perfect sized skimmer for a 55; I personally think that the 90g rating is a little ambitious. Regarding overskimming: I don't believe it's possible to overskim nutrients out of the water, but that it is possible to pull too many trace elements through skimming...

    i need a tank badly

    I won't ship, sorry. The tank and sump are fragile, and the stand weighs about 75lbs. alone.

    Monitor/ Wavemakers?

    There are several controllers on the market that can monitor most of those parameters, and also serve as light timers, wavemakers, and controllers for devices based on monitored parameters. The one I am most familiar with is Neptune System's Aquacontroller. It has the ability to monitor temp...
