All of my equipment is pretty old, and I'm just now reading through all the posts about LED lighting. Are these now considered better than MH? I only have a couple of soft corals and my anemone, but I have been thinking about a new light fixture and I was just going to get another MH. I like...

My tank is getting quite elderly by most standards, and I was wondering about my sand. I changed from cc to sand several years ago, and just recently I've been wondering if the sand ever gets too "old." I still have the same anemone and clownfish pair, the sixline wrasse, and the royal gramma...

I'm considering a madarin for my tank. I'd like to get one of those hang-on refugiums. I bought some of the pods from this site. What I got was a package of green water. Were there pods in this? I read posts about how people see the pods on the glass, etc. I didn't see anything in that...

My calcium is testing at around 320. Isn't that a little low? My alkalinity is 3.5 and the PH is 8.3. I have some "Liquid Reactor" stuff, but it also raises PH. What causes low calcium? I thought regular water changes should keep levels like they should be.

Question 1: Pods I'm looking at a simple hang-on refugium to have some macro algae and mostly some pods in it. I'd like to get a mandarin if I can get the pod thing rolling. How does this work? The pods are reproducing in the refugium, right, so how do they get into the main tank? Is the...

Okay, I have an ******** design question. I'm looking at all of these great pictures of these beautiful reefs, and I've got to tell you, I'm feeling pretty dumb! Why don't the corals that are so close together hurt each other. My corals DO NOT get along. My green star polyps stung the tips...

I'm looking into getting one of these stars for my tank. I think they are pretty interesting, and my tank is sort of invert-less right at the moment. I have a cleaner shrimp and a handful each of snails and hermits. I was wondering what the differences are between these two kinds of stars...

Here are my happy pair of percs! I love these guys. They defend their eggs and their home like Pit Bulls!

Okay, all of you remora lovers, why is this thing still putting a distracting amount of micro bubbles back into my tank???? My "junk" Sea Clone didn't. I know about the break-in period, but it said one to two weeks. I installed this skimmer on March 6. I'm a little let down so far. The...

I recently got the Aqua C Remora skimmer, and I was wondering if I should still use the filter pads that go in my hang-on bio wheel filter. I was thinking about taking the pads out and just using the bio wheels and running the carbon the power filter. They seem to catch a lot of stuff and I...

I've been reading in these posts and in my book, and I have a question. Is the Heniochus a reef safe butterfly. It says that they are plankton feeders, whereas the other butterflies, especially the Chaetodonts, eat corals and can't be kept in a reef tank. I love the look of the long-fin...

I recently switched my 90 and 55 into one 75 tank. I got a good MH fixture (finally) and I noticed that green algae is on my glass pretty heavy. I'm having to use the mag float at least twice a day. Here's what I assume--the new lights are helping the algae bloom, plus when I switched...

I've been searching posts and reading about the Aqua C Remora skimmer, and I noticed lots of talk about how you can adjust the collection cup up or down. Up makes a dry foam, down is sort of a soupy mix or whatever. My question is, which is better? I'm upgrading my tank, and I guess I'm...

Okay, I've tried everything under the sun to fix my Coralife pc fixture, and it still doesn't work, so I'm throwing in the towel and getting a new fixture. Here's the deal: Orbit has the "new" thing called Extreme compact fluorescent, which is 520 watts in a 48" fixture. It is 4-130 watt...

Okay, so now I'm down to a simple question. If a ballast needs to be replaced, can the lights still come on for a while then go back off again? I guess I'm thinking that when a light bulb burns out, it's out, it doesn't keep going on and off. So does a bad ballast just up and die, or can it...

I have a 48", 260 watt Coralife fixture. It has two 65 watt 10000 K bulbs, 2 65 watt actinics, and three lunar lights. There are three separate switches and power cords. For a couple of months the actinics have been going on and off at odd times, and now for about a week they haven't worked...

I am looking at a Tidepool filter/sump unit for my tank. I have a few questions about things that I don't understand. 1. My tank is not drilled. Does it have to be? 2. The tank has a pre-filter box which syphons the water out and down to the filter/sump. It requires a pump and return...

Hmmmm...... I do testing once a week. When I did my ph test last night, it shows it to be very low, around 7.6 or so. This is unusual to me. I tested my other tank and it was fine, plus I used the reference sample in the test kit and it was correct. Here are the other readings as they stood...

I currently have a 90 and 55, both reef. I'm looking into a 125 around the fist of February, but this time I want to do FOWLR, so I can try my hand at some more advanced species. However, the reason I didn't go larger in the beginning was because of the weight of the tanks. I read in a book...

I read post after post about differents things, usually corals and anemones, getting sucked into powerheads, usually with tragic results. I don't really understand this. My powerheads have this pointy plastic guard thing on them that NOTHING could get through. The worst thing I have seen is a...
