DIY rain-system? (low tech)
I hope you'll bear with me because it's not so much a fish tank (yet). I'm having issues actually getting hold of any suitable fish from the local pet store, but it's basically a 110 litre Juwel tank that's filled about 30 or 40 litres of water in, with some bog wood of various kinds, plants (mostly spiderwort/wandering jew, pothos and some other stuff).
Overall I'm happy with the tank, even if it's not inhabited by any fish or shrimp, but I'm intered in making a sort of rain system. It doesn't have to be automatic by any means. I can't figure out a good build with the Juwel tank!
What I tried right now, was a few pieces of egg crate ziptiped together. I made the egg crate narrow enough to fit in, and at the short ends, I used duct tape and fastened it to the sides of the tank (in a way so that the actual hold/pull is on the outside, not just on the edge.) and a little bit of hold on the front aswell. The lid of the Juwel tank hides a bit of the top of the glass, so the duct tape is not visible in front.
For the "backside" of the eggcrate, I was afraid it would start to pull/sink, so I used some hemp twine and just pulled it through a few holes in the crate and duct taped the twine to the outside.
With the egg crate in place, I can place for example kitchen towels on top and just let water soak through and drip down.
The problems are:
1. The crate will eventually be in the way. I can "easily" remove it of course, but it'll be a hassle to remove it every time I want to adjust something below.
2. The drip is unsteady/last only a few seconds.
the good things are:
1. The egg crate gives a little bit of shade and makes sure the plants won't stick right into the lamp and burn.
2. It looks like it's overcast/cloudy when it drips due to the paper towels blocking a bit of sunlight.
My questions are:
Is there any sort of grid/mesh that fits Juwel tanks, that I can put to protect climbing plants from being burned?
Is there a better, more stable way of rain system? I'm not taking about spraying/misting, I can do that myself. I want the appeal of the big rain drops.
I've seen only 1 person who made an inexpensive DIY way of rain drops, but I couldn't get it to work like him. I believe my power head wasn't powerful enough, and he had it over an open tank I believe. I think his method was something like, a powerhead in a bucket and a hose connected that was clamped off, so water would go out through holes instead. This doesn't help me in a closed tank, I think. Unless I can put the system through the feeding lid.
Hope my post isn't too confusing. I hope someone has any good ideas about Juwel-tanks and rigs to it, or a great DIY method of rain drops!
