  1. Something to consider is that in order to heat 1 litre of water by 1 degree, 4,186 watt seconds (Ws), or 1.163 Watt hours (Whr) is required. So for this set up, the wattage (300W) and liters (600l) are known, so over 24 hours, the temperature rise can be calculated as ~14 degrees C from ambient (assuming zero losses - ie/ the tank system losing temperature into a colder room around it etc. etc).
  2. Out of interest, the Medo pump that I mentioned above in 2009 is still going strong in 2015 today :-)
  3. I got into the hobby thanks to my Dad who always had a dream of keeping and breeding Discus but never quite could do it, thanks to the regular moves that being in the RAAF forced on us. My first experiences that I can recall were looking at all the weird and wonderful things being bred in Malaysia when we were stationed over there in the 70's. Then I received my first tank (and 18" er) into which went all sorts of in appropriate things. But around Butterworth (again still in Malaysia) where all these creeks and paddy fields - and all the fantastic things we caught that I never ever saw until much later here in Australia - such as golden panchax, snakeskin gouramis, croaking gouramis, weird bettas that we called "Thai fighters" as nobody knew what they were, and lots of odd rasbora like things. Coming back to Australia I still had the "burn" so to speak and decided to stick to west African cichlids (kribs and the like). That was until 1990 when I went along to the now defunct Pet and Hobby Expo and there was ANGFA with a display of newly discovered Red-finned blue eyes. And all the other stunning fish from around Queensland and PNG. There was rhads from straddie, blue eyes from Cairns, Bosemani from PNG. I was hooked (and I'm in debt to Aquatic7 above who helped transport a poor student to/fro ANGFA meetings in Brisbane from Ippy). And since then I've been a member and locked myself into natives all the way (mostly rainbows and gertrudae), as well as getting into the activism side of things to save our waterways - and travelling the country side looking into all and sundry waterholes. Met a lot of great people thanks to this hobby. Some even on this very list :-). And looking forward to continuing to get the message out there to preserve our water ways and the many and varied things (including H.sapiens sapiens) that depends on them. cya Graeme
  4. I can second Gary Maher. Ta Graeme
  5. Technically he was talking about Komodo Dragons and a trip to Komodo Island (at least his first talk). 2nd talk from him was about his recent work in the NT with landscaping tanks and aquaria. Auction had 8 different lots (ie/ different people) and 10 boxes/bags/buckets. Ta Graeme
  6. These videos were certainly well received at ANGFA Peter. Ta Graeme
  7. Hardyhead - Craterocephalus stercusmuscarum fulvus
  8. I've purchased the entire set including all the reptiles and frogs etc. Excellent quality - beautiful pics. Can highly recommend them as they are very, very cheap! Ta Graeme
  9. Could be TB (Mycobacteriosis). But also could be just age. Like us, we all get old and some of us don't make it to a rip old age due to the afflictions of getting "old". I would suggest euthanizing the fish in order to (hopefully) stop whatever it is. Unfortunately there are a bunch of bacteria which affect rainbows in pretty much the same way, and all have the same result (the death of the fish). Ta Graeme
  10. Personally, I've standardised on 200mm for my stands. Ta Graeme
  11. You could try drilling from the inside out (put your tape on the outside of the tank). Only thing is your cooling.
  12. A rough(ish) rule of thumb is 1 liter per hour >>> 1 outlet. Naturally this will change depending on your exact setup (airstones, depth etc. as others have mentioned above) but it's a start. Ta Graeme
  13. All other medicines have useby dates. What it is for sterazin - no idea. If you have doubts - throw the old stuff away and buy something else.
  14. My 2c worth 1. I would use steel. 2. I have standardised on 25mm fittings, so this is a 35mm hole. Your 38mm holesaw should be fine. Although bigger is always better when it comes to hydraulics. 3. I don't advocate drilling bottoms of tanks. Pressure on the bottom of a tank is 100% of "system pressure" while on the side, the pressure is only that at the surface. 3a. Makes sense to have the inlet and outlet of the tank at opposite ends (although I have both at the same end on many tanks - I just use an elbow on the inlet to force water away from the outlet to prevent short-cutting of the water). 4. Ok. cya Graeme
  15. 62 4 x 6'ers 6 x 4'ers 9 x 3'ers 6 x 2.5'er 31 x 2'ers 2 x 15" cubes 4 x 18" blue eye fry tanks + a dozen or so tubs outdoors of various sizes and a few IBCs in there for good measure cya Graeme
  16. ATO and the Government have some (not so clear) rules - A business or a hobby? | business.gov.au cya Graeme
