Posted by on October 30, 2005, 1:50 pm Please log in for more thread options Hello group, I've bought a Jewel fish tank from a car boot sale. It is equivalent to the Rekord 70 and came with the airpump and heater that fit into a plastic column that goes in the corner of the tank. However there were no instructions, hence this post. On the airpump there is an inlet, containing a small removable plastic plug that the previous owners left in. I can see the old water line is way above the level of the inlet, so I don't think they blew air into the tank with their setup. So I have two questions: (i) If I blocked this inlet like they did would White Cloud Mountain Minnows and Zerbra Danios survive? (ii) In order to suck the air in, I would need to buy and attach a tube. Is that right? Sorry if these seem like dumn questions, but we all have to start somewhere! Regards, Gary Pearson.

The only time it may be needed is if you are medicating the tank - all you need to make it work is 4" of airline tubing. Full instructions are here - http://www.juwel-aquarium.de/pdf/101913_GB.pdf You might like to read this before setting up ;- http://www.thetropicaltank.co.uk/beginner.htm HTH Sue Posted by on November 1, 2005, 2:29 pm Please log in for more thread options Thanks Sue, particularly for the links. They were very useful. A follow-up question... I bought a five in one test kit (the ones with the coloured patches on a strip_ and the reading came out as follows: NO3 = 50 mg/L NO2 = 0 mg/L GH >= 16 KH = 3 pH >= 8.4 However I thought that hard water caused acidic values, contrary to my test kit. I followed the instructions carefully. Are these test kits reliable? Gary Pearson.

Your kH (in dkH?) seems low but not too bad (don't skip your gravel vacuuming). Your hardness at 16dgH is fairly high and agrees with your 8.4pH. I'd add something which brings the kH up naturally. The gH and pH are not going to change too much more. With 50ppm NO3, I might assume your tank is cycled, but being in the UK which can naturally have 5-20ppm NO3, perhaps you should check your NH3/4 to ensure that the tank is cycled? -- www.NetMax.tk Similar Threads Posted Newbie questions October 2, 2007, 8:13 am Newbie questions April 12, 2005, 12:28 pm Newbie needs guidance July 22, 2008, 2:10 pm Newbie help/query?
