I want a heater for a 55 gallon tank. I really like the ViaAqua Titanium (always wanted a titanium thermometer), but then I saw the Hagen E-series. Both seem to get good reviews. Can anyone with experience with either tell me about their experiences, or suggest something else?

I have an old Canon film camera that I'd like take tank pictures with. I'd also like to use it to take tank pictures at the local aquarium (so no tripods allowed). I am debating between the Canon 50mm and the 100mm macro lens. I know the optics are better with the 100mm, but it seems to me...

Nope, there are no scratches on the lens that I can see.

I bought a refractometer from Marine Depot a few years ago. It's worked perfectly---until this week. Now it seems to register only 1.021 for both of my tanks and fresh seawater. When I put pure water in, it does register 1.000 though. After looking at the instructions again, it says to...

I have a longnose hawkfish and a chromis in my tank, and I'd like to add an arrow crab I saw at the LFS. I know longnose hawkfish may attack/eat hermit crabs and ornamental shrimp, but what about arrow crabs? Am I giving the hawkfish a new tank mate, or dinner? :confused:

I just used my Instant Ocean Hydrometer to test the water before a water change. It read 1.026! I used a digital scale to measure the correct amount of salt to pour in (I checked the scale by weighing a pile of quarters), and an air pump mixed the water overnight. Usually it reads 1.024 or a...

I was at the local Lowe's and saw replacement carbon and sediment filters for their home RO units. Is there any difference between these filters and what I buy at my LFS? Do the ones from the LFS last longer, or is it six of one, half of dozen of the other? :confused:

I have a CPR Bak-Pak skimmer which is about 5 years old, and lately it's been making buzzing noises. Otherwise it still functions fine. Does the whole powerhead need to be replaced, or do I just need to replace the impeller?
