  1.  

    This is something I found. I can’t speak to the accuracy of the source but they do address this here:

    https://aquanswers.com/aquarium-safe-paint-durable/

    In the article they state, “Spray paints designed for plastic will become inert after curing. A completely cured paint with fully evaporated solvents is aquarium safe. Never use paints that are mold-resistant as these are toxic to fish.”

     

    I hope this helps.

     

    P.s. I  saw this thread because I was looking for help. I also bought the new formula and wanted to know if it would work on terracotta? I’m going to paint soon. I’ll let it cure for a week and see how it goes unless I hear it’s not safe.

    I don't remember if we filled every single lego in the tank with silicone or not (which would have softened the edges, I think.

    We definitely did not have any fish injuries, not even the time the lego caves separated and floated up.

    Nice. I think I’ll get it a go. If it’s not a total disaster I post a pic. Thanks

    We lost everything in the housefire in 2017.

     

    I don't even have pics of my kids...

     

    Yes, we glued real legos together to make planters and caves for a real cichlid tank. It was a lot of fun!

    A lego built "skull of Grayskull" was a cave that a pair of firemouths bred in reliably for 2 years. A spider plant grew out of the top, because legos like to float🤪 and we weren't bright enough to think about connecting to slate.

    Using UGF exclusively at the time, resorted to silicone attachment of legos to UGF, and then added gravel to hold down both.

    Definitely provided plenty of line of site breaks that were *solid*

    Now that I know more about aerobic and anaerobic bacteria, the UGF probably prevented problems, by ensuring good water flow through the gravel, even in caves.

    Cichlid tanks always had 2 power heads, plus two air uplift tubes.

    They are a lot of fun to build, next time I would drill holes through the legos so they weren't plastic air bubbles 🤷‍♂️

    That might even negate the need for gluing together, and prevent floating. 

    I just posted a question about Legos then I saw this. So there weren’t any issues with the edges (of the Legos)?

  4. I posted this question before and got a lot of helpful advice, which I really appreciated. However, I didn’t get a specific answer. I thought maybe someone might know so I’m giving it another shot. I apologize for the redundancy.

    I made a shrimp cave out of a terracotta pot. I’m really happy with it. I’m hoping it will provide a good place for Bloody Mary shrimp to reproduce. 

    The tank has amano shrimp, green neon tetras, and a scarlet basis also. 

    What is the smallest diameter hole that will allow the Bloody Mary shrimp inside while also preventing the amanos and fish from entering?

    Any help will be greatly appreciated.

    Thanks 😊 

  5. I loved the idea but no matter what I did it eventually started belching out air. I went through tons of headaches with Oase and replaced the whole unit twice plus a new head, gaskets etc. I found online others having the same issue. I ended up with a larger unit (for free from Oase) but it’s collecting dust. That said, others have said they love them, and when mine weren’t purging air they were super. 

  6. The original intake-spray bar project has turned into a MUCH bigger project.

    I’ve been using Oatey PVC cement, PVC primer, ABS cement, and Transition cement for (ABS>PVC). Oatey says all their cements and primers can be used with potable water. So I think I’m good with those (?).

    I’m thinking of spray painting it. Any suggestions for spray paint brands that I could use?

    I really appreciate all of the help. 🙂

    I know that hot glue is aquarium safe, or maybe you could use aquarium safe silicone, but I’m not super sure I’ve just done some research on bonding substances for fish tanks.

    Really? I thought you weren’t supposed to use hot glue (?).

    I personally have never had a problem. However letting it fully cure would be best. I've used many different types of pvc cement. All had the same outcome, no problems.

    How long should I let PVC cement cure?

    I really appreciate the help.

  8. I want to make caves and tubes for dwarf shrimp. I have ideas about what I want to do and use. 
    My question is what is the smallest diameter hole I should make for the entrances. 
     

    I want to make sure the largest dwarf shrimp (CRS) can get in but I don’t want smaller fish trying to use it too and getting stuck. In one tank I have white cloud minnows and in another green neon tetras.

    Any help will be greatly appreciated.

    Thanks
