Ok so right now I have my 6 inch res male in a 20 gallon long aquarium. Which at first I thought would be big enough, but it's not now that he's in there. I didn't really research. Anyhoo, I bought this aquarium without finding this forum first and getting ideas about going with tupperware and what-not. So now I'm thinking about getting a strong tupperware container, but had some questions... (oh yea, and we're super tight on money right now with my husband not having a job right now and baby coming in a couple weeks...)
1. Filter: right now I just bought a new filter, and 318 submersible, and it's working ok, for now. I had a reptifilter yesterday but it died by this morning. Probably because we're using sand substrate. So I'm trying to figure out what kind of filter to get if I buy a larger container. I can't get an xp3 or anything like that. But I have a 30 dollar credit to petsmart right now. I'm wondering what filters work best in the tupperwares, since they have those weird edges on them.
2. Container: where's the best place to buy one? Which ones are strong? I heard that they tend to bow out with water in them. Is it better to get a colored one or clear one? It seems the clear ones are flimsier, but at least you could see through. Also, what kind of stuff can I put it on? Right now my tank is on my sewing machine table, which is handbuilt strong and made of strong wood. But I'm not sure how much weight it can hold. It's had my turtle tank on there before and a computer. I was thinking of setting a container on our coffee table, but my daughter uses it for coloring, so I don't think I wanna use that.
3. Heating: right now I have one of those new reptile submersible heaters that's enclosed in the plastic, but it seems to be keeping my tank at 75 degrees, so I'm not sure how it'd do in a bigger tank.
4. Lights: I have a hinged metal cover over our aquarium right now with a strip light with a uvb light in it, and then a basking light with a halogen "household" lightbulb in it. I know with a bigger container I'm not gonna have a cover, so I guess I can clamp on my basking light, but how safe is that to do really? And how do I get a UVB light on there without a strip? I was looking into those mercury vapor lights that produce uvb and heat, and that seemed like a great idea, but what kind of clamp lamp do you use for that? I'm guessing it produces a lot of heat too.
5. Basking: I have a turtle ramp I just got. I'm not too impressed with it, but it works. Do suction cups attach just as well on tupperware/other containers as well as they do on aquarium glass? And how do you prevent escape if you can't cover it?
6. Substrate: right now we're using a very small layer of sand and river rocks. I know sand is controversial, but the turtle loves it and it seems to be heavy as when he kicks it up it doesn't hang out floating around in the water. But what filters work best with sand substrate. I don't want to have to get rid of it.
Ok, well thanks for listening and I hope ya'll can help me. Right now I've never seen my turtle so happy and healthy. But I want better for him, and I hate always thinking "this will do until I can get better..." as it's been like this for 13 years.
