Christopher Marks Posted November 22, 2017 Share Posted November 22, 2017 Maintaining a pico jar is a little bit unusual compared to a traditional nano reef, but there's no need to be intimidated! 100% water changes are a key element of success, community member @gena has kindly documented the process for anyone out there who might be afraid to jump in to keeping a pico jar.

JoeR Posted December 30, 2017 Share Posted December 30, 2017 The real question is how to drain the water in a tank that’s too small for a regular hose? Airline tubing would work, but how do you get the vacuum physics to work? This is a problem I have come across with my half gallon. I’ve been dumping it but that makes cleaning the salt residue off the glass a major pain. 1 Quote Link to comment

You wouldn't be able to clean the sand very easily though, I wouldn't think. Have you tried the airline tubing? Quote Link to comment

The tank I have has less than a measuring cup of sand in it so it would probably be easiest to stir it up real good and then do a WC rather than vacuum it. 1 Quote Link to comment

The diameter is too small and the water doesn’t flow, youd probably have to start it with your mouth like a straw but that’s gross lol so have to dump it still :/ Quote Link to comment

It does work I just tried it to confirm. 8 fluid ounces drained in 34 seconds... so miserably slow. I filled the airline up with RO(tap would work) and plugged both ends keeping them up to ensure the water was in the lines then submerged one side and lowered the other and a siphon began. Physics for the win. If my math is right it would take about 9 minutes just to drain a gallon though. If it didn't work no one would use check valves on air pumps. 2 Quote Link to comment

Problem for me is that I can’t get water to go inside the tube, even when submerging it. What material and diameter tubing did you use? Quote Link to comment
MainelyReefer Posted January 1, 2018 Share Posted January 1, 2018 Picture of tubing used and the brand. I'd say it's 1/4" but it's not disclosed, it is standard airline tubing though hold the tube to a running faucet it will force its way through 1 Quote Link to comment

Maybe look for something like that. I think I got it at Marine Depot. 1 Quote Link to comment

brandon429 Posted January 2, 2018 Share Posted January 2, 2018 Ive had planted tanks so small it took three airline tubes all running to drain em multi approach to airlines. I could have used the half inch drain hose for a quick run, but those systems I didn't want the sandbed sloshing around, so I went for a calmer drain via 3x sep air lines. 1 Quote Link to comment
Alfredo da reef guy 85 Posted January 2, 2018 Share Posted January 2, 2018 The way I clean the sand is blast it with a turkey baster. Pretty much how I do it before a water change. I blast everything and keep it suspended in the water column for an easy syphon. 2 Quote Link to comment

What material and diameter tubing did you use? like @gena said: get yourself something with a syringe if you don't want to suck on it. Also use clear tubing so you can see if you have any air bubbles in it. You can use the syringe to push water into the line or suck it out. doesn't matter how you fill it. Only that it is filled, and there is no air in it. A single air bubble can break the siphon. I use 50 foot runs for some of my tanks, and trying to restart those can be a real pain when some air from an air stone decides to get sucked in. 1 Quote Link to comment
