    Return Pump

    I wrote wrong. The DCQ-5000 has a wave controller. It pulses the flow with the speed depending on the controller setting. The DCP models are the sine wave controllers for steady flow. I believe they are the same pump, different controllers. I have very short LOC lines from my return so they...

    Return Pump

    I was using an older JEBAO DC 4000 and now have a DCP 5000 (but am using the DC controller - See the Shelly Tank thread). Basically the number is in liters/hour so about 1060 and 1320 GPH. You lose some flow due to the height difference (and piping) so I feel I am getting about 650 GPH for the...

    The SHELLY tank

    I decided to make a few changes. First, the micron socks fill up fast and overflow in 2 or 3 days. Since I drain directly to the sock (most sumps do not do this), the back pressure changes as does the water level in the overflow. Since I have a straight drop down, any water going down the...

    Elusive equipment not on the US market

    Lots of European companies (Orpheus) have items in other countries that won't sell enough to get here or will eventually find their way. There are lots of Chinese items that may be very good (Dsuny) as well, but don't sell well here or have no distributers or they may be producing almost the...

    Sand thieves, forensics, and the Queen

    So what you are saying is that Singapore has been soiled by the work of dirty sand thiefs. The real question is how do the forensic technicians get fingerprints off of the sand. At best, I would think they would be too grainy.

    Is it worth it?

    Does it fit the space you have? Does it have enough room underneath for a reasonably sized sump with headroom? Has the stand had water damage? The problem I had with used aquariums of that size was finding one with a reasonably high or well made stand. Too many of them are too short and...

    The SHELLY tank

    The sponges were hitch hikers. The purple sponge was on an acan frag (so were asterina starfish) I won in a raffle at my first Reef Club meeting held by the Raffle King - Anthony. I like purple so I wanted the sponge. I have a few pieces to bring to club meetings. I even entered a picture of it...

    The SHELLY tank

    And here are the rest of my initial tank inhabitants. I started with one harry mushroom and now have 8 or more in 2 spots. I brought over some of the mushrooms from the Drink Tank Challenge nano aquarium to nurse them back into health before finding a spot. The anemone has split in 2. both...

    The SHELLY tank

    Here are a few items in the aquarium. First I brought over the purple sponge from the last tank on the rocks I turned over. I have it several places so I will need to keep an eye on it. I also brought over some blue encrusting sponge. It is receding a little in the brighter light and zoas are...

    The SHELLY tank

    I have never had a problem with them and other corals. Once mine find a spot they like they usually don't move. But then again, I don't have a lot of higher end corals.

    The SHELLY tank

    Here are a few flower anemones in the tank. they were all at the sand level in my last tank which wasn't the best with the goby moving sand. I do feed them occasionally as they are less in the food path currently.

    Coralline Algae

    I live in Jackson, NJ. I do have a few rocks in saltwater from my last tank. They are not under bright lights, so there is not a lot of coralline, but enough on a few. Hitchhikers could include some pods, snails, worms, aiptasia, green bubble algae, and purple sponge. Send a conversation if you...

    Coralline Algae

    https://arcreef.com/product/coralline-algae is a source. I personally think that the hitch hikes are one of the most interesting aspects of a reef tank, being amphipods, copepods, fan worms, sponges, snails, hydroids, various crawling worms or coralline algae. Some like aiptasia are a pest, but...

    Coralline Algae

    Most people have rubble with coralline on it. I got a empty frag from Ultimate Corals to get the coralline algae (The coral probably released from the frag). I have bought a coral with coralline on the frags; many frags have some (and on a few occasions, the presence or coralline algae...

    Coralline Algae

    I started with frags containing the colors and types of coralline algae I liked. Keep the calcium, magnesium and alkalinity high enough (and replace as needed) Coraline algae removes calcium and can deplete it. And you need enough light to get it to grow. Essentially, corals tend to settle and...

    The SHELLY tank

    I had a problem with my original sump shown below. I cracked the glass separating the return. I had originally planned to use stained glass, but it was too thin. Essentially, the water came in through the sock and either flowed towards the refugium or the skimmer, then around the refugium and...

    The SHELLY tank

    Besides the usual snails and hermit crabs, this tank has a fire shrimp and a serpent star. It also has asterina sea stars. I hope to establish some small micro brittle sea stars as well.

    What's Wrong with this Offer?

    I agree with Mark. I went to this Petco in Brick because 3 others I went to didn't have 20 gallon tanks, and I needed one to fix my sump. It had by far the best saltwater section of any chain store I have seen. I still have fish from Petco when I started my first tank, before I found out about...

    October 2018 Meeting

    Feng's is a great place to go. Feng frags from the corals in his display tank. He is not big on named corals. I love going there.

    Green Bubbletip

    There were several small ones at Allquatics in Hamilton and Philadelphia Aquatics had 3 types on their web site.
