Diatoms and Cyano Bacteria

Now this is weird. In an established tank, I all of a sudden have red dust and red algae covering everything. I will be performing some water changes, but I have taken photos for those who are searching the net for examples.

  • First image with the green arrow is the Cyano Bacteria or red slimy algae as it is sometimes referred to.
  • Second image is the diatoms or the red/brown dust.

Both of these should not appear in an established tank! It should only occur during cycling.

A good article I ran across is here: http://www.nano-reef.com/forums/index.php?showtopic=132956

Driftwood Stories

Had a piece of driftwood for my freshwater tank for some time now. Prior to putting it in, I had already soaked it in water for 2 months, changing water weekly. Still the piece of wood would turn a 200L tank into a tea like colour after only one week. I put up with it for over 6 months, but I believe it was unhealthy for certain type of fish that didn’t like the tanin like acid in the water.

So today I decided to boil the driftwood. After 5 hours of boiling, and 3 water changes in the pot, it was still leaking a very dark tea colour. What a waste of time! Ended up binning the piece of wood, and I might have to find another. It looks like if 2 hours of boiling doesn’t get rid of the colour, then you’ll need over 10 hours worth. Too much effort for me over a piece of wood!

Marine Wipeout

Thought it was about time this got blogged!

So I got back from my Japan trip of 2 weeks, and then off to Sydney for about another week. All up about 3 weeks. Didn’t think that would stress out the tank too much? Wrong… the ecosystem must’ve be overloaded with Nitrates by the end of it, and the Mono Sebae and Royal Dottypack passed!

The clown was showing very poor behaviour and was very sluggish. He also wouldn’t eat. Any fish keepers out there would know that the fish has pretty much had it at this point. I could tell it in his eyes that he was in bad shape. It also looked like his skin had algae on the surface.

Drastic action was required.

Quickly drained out the water (almost 80% in fact). Topped it back up with freshly made salt water. Netted the clown and bathed him in freshwater which removed all the algae like material from his skin. Popped him back into the main tank.

He still looked stressed and sluggish, but come the next day, he was back to his usual self again! Quite a turn around, and I dare say only a clown could take such stress. Quite a tough little guy!

PS. Since then, I’ve been trying to sort out the balance of my marine tank and have since introduced live rock. Due to the ammonia spike created with live rock, the clown has been relocated to a quarantine tank. He’ll have to live there for a while! Will keep an eyeout on the ammonia/nitrite/nitrate levels and do water changes as required. It just has a filter (with some filter media from the established tank) and a heater in a 20L plastic tub. If there is any issues with this, someone please make a comment on my blog now!

Australian Desert Goby

Was changing water in my tropical tank and thought I’d take picture of the goby I have in there. He is fun to play with and not scared of too much.

 He’s an Australian Desert Goby. Tough as nuts they say, because he lives in Lake Eyre which is meant to be a freshwater lake, but can get dry and conditions deteriorate to extreme salinity levels.
