I'm looking to upgrade my mini 10 gallon sump on my 125 gallon. They way I built my stand back in the day with a center brace means I can't fit a tank with a width more than 32 inches down below. Would it be okay to have two 20 gallon tanks as part of the sump as pictured below? Do you see any...

I'm in the market for a skimmer and have the chance to buy a new Coralife 220 for $125. I know this won't be as good as other high-end skimmers out there, but would I be happy with it for my 125gallon reef? I would eventually place it in my sump. I've got to let the seller know today. Thanks!

Hello, I'm planning to buy a pack of Rod's Food, which just comes as a big frozen flat. My question is, how do I feed just a bit of it to my tank? I know you can break of chunks here and there, but it seems like the pieces will still be too big, and when it gets to the middle of the pack, it...

We had a pretty good storm move through the area a few hours ago. I'm at work right now but my mom stopped by my house and said our power is out. My backup plan has included a power inverter from my car, or running a cord to my neighbors (who are on a different grid and currently have power)...

Hello, I just ran my full line of tests tonight, dKH is 6, Calcium is 440 and Mag is 1200. I'm in between water changes and have just a few SPS and LPS is my 125 gallon. I'd like to raise the alkalinity a bit. Would you suggest baking soda or Kent Marine Pro-Buffer dKH? The pro-buffer is a...

Tomorrow I'll be getting 12 new T5 ATI Bulbs to replace the stock ones on my Current Nova T5 Fixture. I'm guessing the new bulbs are going to have quite a bit more par than the stock ones. From the below options, what would the best way be to acclimate: A. Install 2 new bulbs a week for 6...

Okay, beyond newbie question but something I have never known. What is the correct way to pronounce actinic? As in actinic light. Is it - Ack-Tin-Ick with three full syllables? Is it - Act-inic with two syllables? Or is it something else?

My week old birdsnest is beginning to bleach a bit at the base. It appeared to be doing fine at the bottom of the tank and only started doing this when I moved it higher up in the tank two nights ago. It was at the bottom for a week. Do you think I should leave it as is or move it down a bit...

So my tanks PH is typically always 7.8. It doesn't matter the time or light schedule, it's always 7.8. I know this isn't terrible, but as I'd like to get more and more into SPS corals, 8.2 will be better in the long run. Today we had one of the first days in a very long time we were able to open...

Hello, I met a local reefer on Tuesday night and traded/bought a few new corals. This is my first try at SPS so we'll see how it goes. 48 hours in and everything appears to be healthy. Unknown yellow polyp he had extra of: Green star polyps with two mushrooms: Birdsnest: Unknown...

Does anyone here use red sea salt? It's on clearance at my petco for $10 per 50 gallon mix. I currently use reef crystals but figure it would hurt to mix it up once every now and then.

Something I’ve just always wondered! - I’ve seen many reef tanks with the aquascaping consisting of rocks stacked against the back of the tank or stacked up in the corners. When this is done, what goes on beneath the rocks where you can never clean? Is it full of detritus? Even with flow...

Here in Wisconsin we don't exactly have the best reefs to explore, but we do have some awesome lakes! I took a few underwater pics with my crummy camera and waterproof case during our vacation last week. I hope it's okay they're not exactly "reef" pictures! What it looks like down there...

The plastic/acrylic welds on my float valve broke where the corner of the L would be on the piece. It seems like there wasn't much holding it in place to begin with. What can I use to glue it back together? Would basic aquarium silicone work? I need to fix it asap as I'll be out of town all next...

I finally got my dual input TDS meter, as I've been expecting that my filters were getting worn. Input is about 700ppm and output is around 30ppm. While the output definitely isn't good, I though it would be worse. I'll be ordering a full line of new filters and membrane today - also might...

My TDS meter arrives today and I've got a feeling I'm going to be needing a new membrane. I've got a Water General RO585 system. Where do you all get your replacement membranes from? Any suggested sites? Thanks!

I know there isn't a perfect answer to this, but I think I might be overfeeding. I currently feed roughtly 1/2 a cube of mysis shrimp a day for my 3 fish: a clown, medium mimic tang, and six line wrasse. Typically I skip a day a week. I also put in a small square of seaweed for the Tang 2x a...

Nothing too fancy here, but I'm excited none the less! Frogspawn: Zoas: I'm embarrassed to say I forgot the name of this. Australian something. Can anybody help? I know it's semi aggressive and needs medium to high lighting.

While beginning to suck out flatworms, I stuck my bare hand in the tank and immediately felt a shock on the tip of one of my fingers. Freaking out, I immediately unplugged everything and tested the water again with the same finger, it shocked a bit, but the more I touched the water the more it...

Well, after much debate and going back and forth several times, I finally decided on a 72" Current Extreme Nova Pro T5 fixture. It's got 12-36" bulbs - 6 12,000k white and 6 420nm Actinic. While its not as cutting edge and sexy as LED, the price was right and I love the fact that I'll be able to...
