I believe this black sponge started on a hammer coral. It doesn't seem to need any light to grow. Is anyone out there a marine biologist?

This sponge type stuff has infested my live rock over the last few years. Can anyone identify it and tell me how to get rid of it? It adhears to the rock like a layer of skin. I have been removing it manually, taking the rock out of the tank and scraping it with a dental pic and tweezers...

What is the maximum allowable aquarium height for a reef tank? Has anyone seen a tank 40+ inches heigh?

Purchase the Iwasaki 250Watt 6500K bulb. It is MV and one of the best bulbs for corals.

You must be correct. I thought HQI was a double ended bulb. I did a search on the net and came up with this definition: HQI = Metal Halide Lamps with a high CRI and/or European DE and some SE lamps

PFO make the 400 Watt HQI ballasts: AQ1-400HQI-120V AQ2-400 HQI-120V Ushio make 10K 400 watt HQI bulbs

Has anyone installed this setup, side-by-side; in the same tank? --- Ushio 10,000K/400Watt, HQI double ended bulb --- Iwaski 6,500K/250Watt, Mogul bulb Does it look ok, or out of place? Would the contrast be too much, or would they blend? Are the HQI double ended bulbs and ballast worth the...

Does anyone know the contact information for Rainbow Lifeguard? I need to know what the Rainbow Lifeguard bulkheads are made of because I need to glue some pipe to the bulkhead. Thanks,

Excellent board. Thanks for the clarification. I'll just stay away from ABS altogether. I'm not sure what exactly would/could leech into the water, but why take the risk.

Incorrect. The ABS more popular and less expensive that PVC. ABS is the flat black pipe most often used for plumbing the drains in your house. The PVC pipe I finally bought is grey, shinny and heavier than the black ABS pipe, and is about 1/3 more expensive than ABS. I traded the stuff in...

Is this true; does ABS plumbing kill fish and others in the reef tank? I am going to start plumbing my sump and was told to never use ABS. Use PVC. Just wondering if anyone else has experienced problems with ABS. For thoese of you who don't know the difference, ABS is the black plastic...

I read up on hyposalinity as you suggested. I will give it a try if I can catch the fish. He is in a reef tank and next to impossible to fetch out. Looks like only one fish has the ick and smokey eye problem so far. The blue Regal Tang. Will all the other fish also get infected now? Hope I...

Thank you. All replies are appreciated. That's the beauty of gathering information from these bulliten boards. I have learn't to screen all information; whether it be the net, books, LFS. Everyone agrees to remove the fish from the reef tank. At 6pm tonight he would not come out of his hiding...

This morning I noticed my Blue Regal Tang's left eye is completely glazed over to the point he can not see out of it. It looks like real bad cataracks. Just in the one eye only. Last week it looked like he had some ick spots, so I treated his food (blood worms) with EcoSystem's Garlic Elikir...

They are twice the size of a quarter and have pink tips. That small clown fish in the pic is abount 1". I have seen aptasia and these look nothing like the aptasia I am familiar with. Unless aptasia come in many different forms.

I bought a piece of live rock with these small Anemone. What are type are they? They have multiplied in the last 6 weeks but not moved from the rock they came on.

That is an excellent explanation!!! I will plumb for a 2" pipe and adjust the outlet hole size to accomidate the desired spray. Most likely I will T off at the top, so I can have water circulation out of two pipes in two different directions. Two 1" spray bars being fed off the 2" pipe. Thank...

The Iwalki RLT is differerent from the XLT. Yes the XLT says it is for circulation but the 100RLT is designed for high head pressure. Would I be better of plubing with 3" rather then 1"? Do you have the web site that explains this? I'm sure there must be a formula. Any rocket scientists out...

Guess I should clarify the question. Will an Iwalki 100RLT pump push out more water at 14 feet if it is plumbed with 3" hose or smaller 1" hose?
