  3. Cool 6 Day time lapse video: Hemianthus callitrichoides
  4. What you have sounds enough for a 40L tank. Bristlenoses grow quite big. Why not get a few more neons or if you want some variation perhaps some glowlight tetras. I have always liked the look of a mixed tank of glowlights and Neons
  5. Those ones that just sit above the water like a Flouro are just gimmics really. IMO. Otherwise they would be unsafe! If you getting one i'd go for one of the ones where water is pumped through a closed unit with a U.V bulb like this: or even better a ladder one like this: Not really necessary on a FW setup though IMO
  6. looks cool Ben. The Monti cap has a really nice colour now
  7. Go for Eheim, I swapped my King return for an Eheim and its way quieter. Otherwise try and stop the vibrations of the king... is it just the hum on the motor or is it vibrating on the glass? also look at the return pipe to see if that is vibrating against anything causing noise.
  8. :roll: didn't you stick a heater in the barrel? I bet you won't have any friends in the tank tonight! I normally do 70L changes on my 220L tank with unheated water. Is everything ok?
  9. ha I just wrote an essay on that a few days ago purplecat
  10. sorry bill- thanks mark
  11. and an article about speciation in lake Malawi- good read Link Removed As above.. Both links over twice the screen width. Bill. Mod
  12. since I haven't posted on this thread and I am waiting for Warren to check my updates in the My Tank Section I thought I'll put up a pic of my tank, as of today, after stealing half of wasps corals :oops: ... 6 Months ago... Today... Peace!
  13. "The growth and subsidence of coral depends on a number of requirements: temperature, irradiance, calcium carbonate saturation, turbidity, sedimentation, salinity, pH and nutrients. These variables influence the physiological processes of photosynthesis and calcification as well as coral survival. Coral calcification rates and extension rates have been highly correlated with sea surface temperatures and to a lesser extent, incoming surface radiation." "Coral growth can depend on both minimum and maximum seasonal temperatures. What is shown here is that, at least for Acropora branching corals, while growth can be approximated to a logarithmic function, particularly over several years growth, a rational polynomial function provides a more accurate model for growth." "Over the period 2004-2007, involving several cycles of SST change, rate of growth of Acropora palmata is largely proportional to the change in SST. However, as temperatures approach those where bleaching can occur, i.e the maximum sustainable temperatures for coral growth, rates of growth can fall" Crabbe, M.J.C (2007) Global warming and coral reefs: Modelling the effect of temperature on Acropora palmata colony growth. Computational biology anc chemistry. United Kingdom. Oh and for those that don't know, SST's stand for Sea surface temperatures

    black algae

    hmm yeah if you treat flourish at double dose it will prob make the hair algae worse! I had it really bad in a 2 ft tank but added more stem plants and dosed 10 ml every other day and its pretty much gone now after two weeks (touch wood) I'll prob start dosing 5 ml every second day instead now!
  15. hey I have some of that! (BRYOPSIS that is!!!) more reason I should have got back to you quicker when you were selling your Hares cookie!!! I have been manually removing it and have been fine so far. to see what a pain it is just look here! http://www.google.co.nz/search?client=f ... gle+Search
  16. only 35?!!!! The ones at hollywood were selling for $150 if i'm not mistaken!
  17. hehe love the gba poking her head into the photo!
