5 gallon -> Frigid 'Catalina Goby' Tank


NanoTank1

Recommended Posts

So I ordered a custom 5 gallon - 18" long x 8" wide x 8" tall, 1/2" thick tank from Advanced Acrylics. I'm thinking I have weeks to prepare for the arrival of the tank. Imagine my surprise when I receive a UPS 'for delivery tomorrow' notice.

 

I'll write a brief review of the tank when it arrives.

 

I'm 100% not set up for this tank yet! I have previously asked a few questions and received some great answers. Thought I would consolidate this thread to keep track of the tank over time.

 

As of now I'm leaning towards tank to inline pump (Cobalt E-X-T 800) to external media reactor to chiller back to tank.

 

Two questions to start with.

 

  • Any specific recommendations for a simple, unobtrusive media reactor? I want to avoid a massive build-up of equipment (like I have with my tropical reef tank!).
  • Would inline UV be useful? Or is it more of a gimmick?

 

Thanks!

For a coldwater tank mechanical filtration is after a chiller as the most important aspect in your tank. Is it an aio?

Thanks, good to know. What is the reasoning behind putting the mechanical filtration after the chiller?

No, this tank is not an aio and is also not drilled for a sump.

Cool. Any thoughts on suitable means of mechanical filtration given a 5 gallon non-aio tank? I'd like to save money here in favor of 'pouring' it into a strong chiller. Same time I'd like to keep the filter out of the tank for aesthetics.

haha that is funny. I would use the ac personally. What chiller are you using? If you need help picking one head over to the biotopes section and ask the coldwater expert aquatic engineer or stu.

Haven't decided on the chiller yet. I want one that can chill the tank 35 degrees or so. That way I don't need to leave the air condition on in the summer. Makes sense, .. I'll head over to the biopes section and ask for a suggestion.

 

I'll reconsider the ac. I wander if that alone would provide enough flow for the tank. Flow to and from the chiller would add some as well. Would be really cool to get a riptide going once it comes out...

Awesome. What else are you planning to add to this tank?

 

That's the beauty of it. I'm very much starting from scratch in terms of expectations. I'll need to do more research into the possibilities. It's hard to get a sense for what would work and what wouldn't.

 

Ideally a majority of the inhabitants could do well with a once a week feeding. An oddball tank would be cool. Offhand I like the eccentric sand dollars and a few others.

 

Do you have any favorites?

If you like odd ball than look into a navanax. That was the reason I stuckk with the idea of a coldwater for so long. That's define tally my favorite :)

They are definitely awesome. I take it you have owned them before. What did you feed them and with what frequency?

No I haven't kept one yet but I have been planning a tank for one for a while now. In the wild they eat nudibranchs and bubble snails but some studies have shown they even will prey on fish when given the opportunity. In aquaria you could feed yours marine snails removed from there shells. If you have an Asian market around you, they will most likely stock marine snails pretty cheap and you can feed him those.

 

 

frequency you can feed them three times a week.

Now I have this image of a Navanax stuck in my head. Worse yet, I have this irrational image of a Navanax fighting a Mantis shrimp. It's like those old Godzilla movies...

Hahaha that's funny :lol: . Ya they kind off do that to you. Get the idea off them stuck in your head and then you just have to have one.

How would you light a coldwater tank in a modest fashion? It's unique in that you don't need high par values and yet still want the tank to look good. I also don't want my tank to look like a freshwater tank if that makes sense....

What ever you like for it. I like white light personally for a coldwater because it looks more natural

I like a natural look too. In this instance I want the tank to have a blue cast over it. I see one Par38 bulb that I like. Unfortunately it only covers 12" as per the stated specifications. I wonder if hanging it higher than spec would be an option...

Link to comment

I don't see why It would be a problem since there isn't any thing that needs a ton of light.

 

Cool. I'll give it a try.

Still have a concept I am mentally wrangling. A 1/10HP chiller requires a flow of 200 gph or so to avoid freezing up. On a 5 gallon tank that translates to min 40x flow. Is that an okay flow rate for coldwater?

There aren't any temperate photosynthetic organisms so you can hang it as high as you want, you don't need any intensity.

 

Hah, for a grand total of $29 plus shipping I went with this one. Now back to contemplating what type of filtration I want:-)

 

  • PAR38 Royal Blue Aquarium LED 5-455nm Blue 21W

You realize that light has only royal blue LEDs, right? You won't be able to see anything that you put into the tank since it won't reflect that blue or fluoresce.
