  Frustrated with seachem reef salt - ideas ?

  Posted: February 28th, 2011, 12:21pm CST by neo

  Hi all,
  been having some issues with my seachem salt.
  I buy the 6.2kg bags of seachem reef.
  Last 4 bags I bought did not disolve completely, leaves a fine residue, but not powder like, feels like small (<1mm) 'balls' when you rub it between your fingers, about one handful of this is left each time.
  I mix 2kg salt to 50litre water (1.026 salinity), I heat the water to 26degC and have a 6000l/min sunsun pump in the drum to stir things up and it is mixed for 24hours before use.
  
  Each time I do a wc I have to filter the water when pumping it to my system else the white stuff ends up in my system and settles where-ever the flow is the least.
  
  Any ideas why ? am i doing something wrong ?

  Fish behaviour

  Posted: October 25th, 2010, 4:56pm CDT by neo

  This is the story.
  I have 4 decorated firefish, I've allways been a bit cowboy about them cause i was told they jump and i must close my tank but i never did and they havnt jumped yet.....tik-tok......
  Last wednesday i noticed one of them hovering close to the water surface in the corner that forms between the back pane and overflow box, and it stayed there.
  Thursday he did the same and i also realized one of the 4 were missing - so i started looking on the floor and behind the stand for a corps - nothing, then my little corner-hovering friend made me think maybe the missing one went into the overflow box.
  I grabbed a flashlight and yes, there it was swimming at the bottom next to the durso, now what, overflow box is 100x200 and 600 deep.
  I pulled the durso out from the tank connector and the missing fire was flushed to the sump where i spend a good 20min to catch it between all the equipment.
  After this the one who hovered in the corner stopped doing this and everyone is happy and eating.
  
  Now I'm thinking, did that one fire knew his mate went over ? are they family or best buds or something ?

  Life on rock disappeared

  Posted: October 20th, 2010, 9:53am CDT by neo

  Howdy,
  the 'life' on my life-rock disappeared.
  I had a lot of PODs all over before but now they are all gone when looking with a torch after lights out, I had huge pods looking like schrimp before, all gone, all that's left is the orange-colored worms.
  Any idea why ? how can I get these back ?

  All of this started after I removed some liferock that i suspected gave me cyano, cyano is gone but i have this brown stuff now.
  The initial brown stuff was hair like and I removed top layer of substrate and cleaned it and returned it to the DT, thereafter I got this diatom like stuff and it wont go away.
  I have since started using diff salt but this brown stuff was there before the salt change.
  Cant upload picks due to server upgrade, will do as soon as possible.

  T5 tube arrangement, packed or spread

  Posted: August 26th, 2010, 1:55pm CDT by neo

  Hi,
  my light unit packs 8 T5 tubes into about 360mm of single reflector space.
  My tank is 650mm front to back so the light unit covers about 55%of the tank depth(front to back distance).
  Would spreading the 8 tubes evenly within the 650mm tank dimension provide better lighting for the corals than what is currently the case ?

  ATU got stuck - ideas on commercial units pls.

  Posted: August 4th, 2010, 9:50am CDT by neo

  Morning,
  :angry:
  Got up this morning to a strange sound from the tank's side of the house, went down and realised the ATU got stuck somewhere during the night and dumped 25L of RO in my tank, with the ATU pump becomming an air pump.
  It is again the relay that broke, 2 months ago the relay stopped working in the off position (normally open), this time in the on position.
  I'm a bit gat-vol for this DIY ATU idea cause it's giving me shit
  
  Any suggestions on commercial ATU ?

  My sump idea - your comments

  Posted: August 2nd, 2010, 1:22pm CDT by neo

  Hi,
  with some posts about water movement, water circulation, dsb contact time etc. i came up with the following idea, what you think?
  
  Instead of the normal:
  overflow - skimmer - dsb - return
  type of sump why not have the overflow go directly into the return chamber with a big return pump so you have lots of water going through your DT.
  Then you have a small 300l/h pump also from the return chamber pumping water to the skimmer chamber, so you have small flow through the skimmer and dsb back into the return chamber but big flow through the DT - return chamber.

  Pls. explain pump control

  Posted: July 27th, 2010, 10:44am CDT by neo

  Hi,
  looking at doing some DIY automation.
  Could someone pls explain how these pumps work where the flow is controlled between 0 and 100%.
  Are these pumps DC pumps and then you just control the voltage to them ?

  Moonlight - LED striplight from Makro

  Posted: July 22nd, 2010, 12:39pm CDT by neo

  Hi,
  I'v been looking for a moonlight for my tank when I saw this (and bought one) at Makro Centurion for R159.
  
  
  Opening it
  
  
  and check the kelvin rating
  
  
  
  this unit is the smallest and you then get it at increments of 3 leds at a time.
  You also get them in a flexible silicon option.
  This 6 led unit gives 1.44watt, 72 lumens, 135mA
  
  The bigger units are a bit expensive compared to the 6 led unit.
  
  More info at
  lumeno LED lights
  
  I bought this yesterday and last night I went to a demo of a security vehicle which was fitted with 2 of the big brothers of this 6 led unit, the light at night inside the cabin was amazing.
  
  light in my tank is very good, maybe to bright for moonlight purpose
  this was taken with my cellphone with the led lights with all other lights in the house off.

  RDSB container

  Posted: July 6th, 2010, 2:27pm CDT by neo

  Hi,
  I am planning on setting up a remote DSB, purpose being for a larger DSB and to free-up some space in my sump for other things.
  I had a look at the big crate-like containers at plastic world but the walls are very thin and the containers will most probably deform when i add the sand/water.
  
  Any suggestions for what container i could use?

  BEWARE: Pump / heater suckers

  Posted: July 5th, 2010, 10:00am CDT by neo

  Was cleaning my heaters and return chamber this weekend, this included cleaning the return pump.
  While cleaning the return pump i noticed the suction feet were a bit slimy, started cleaning these and then realised that the plastic/rubber it was made of was actually breaking up and this is the cause of the sliminess, checked the return chamber and there were a fine deposit of black 'stuff' which I assume was coming from the rubber suckers busy breaking down.
  
  I then checked the suckers on my heaters and they are not there yet but i think they will also end up like the those on the return pump.
  
  Has anyone had similar experience ?

  how does a QT work ?

  Posted: June 30th, 2010, 9:38am CDT by neo

  Stupid question I know but...
  How does one run a QT tank ?
  I know it's a seperate tank with its own water that's not shared with your main tank.
  
  Does it have substrate, lights, sump etc. ?
  Are you suppose to run it all the time or do you drain it and only fill it when you have new/problem ls to care for ?
  
  pls educate me on this one.

  why aeration did this ?

  Posted: June 29th, 2010, 9:46am CDT by neo

  Hi,
  In my battle against cyno I dumped an airstone in my sump last night.
  Within 30min the water was as clear as, well, glass.
  The water has never been this clear/bright.
  Anyone know why ?
  O, I am the one who had an accident with (over)dosing carb(baked bicarb) on sunday, maybe this + the extra air did something ?

  What to do ?
  Leave it, water changes? please help

  Posted: June 21st, 2010, 12:36pm CDT by neo

  Hi,
  i found a device which could be used for auto topup purposes BUT
  it uses probes made of stainless to be inserted into liquid.
  You think these stainless probes will last some time or not?

  Sea temp on surface and deep down

  Posted: June 18th, 2010, 2:27pm CDT by neo

  Hi,
  with one or two threads on heaters and water temp and my own experience the last 2 weeks I was thinking:
  What is the sea temp at 20 - 100m ?
  Why do we want our tanks at 24deg ?
  Maybe the temp at depth where our livestock normally occurs is lower than 24deg ??
  
  So I GOOGLED, found some info, still no straight answer for me, I will share what I have found and ask for your opinion.
  
  First, we have easy access to the surface temp measured by satellite, here's an example:
  
  
  
  but what happens lower down cause the above measures the top micro meter of the water.
  
  water temp in the sea looses temp according to the following graph:
  
  
  
  The thermocline region is where the sharpest decrease in temp occurs and is typically the top 50 - 250m according to some sources.
  There are other sources which uses the following graph:
  
  
  but from this, how close to the surface temp will it be at say 50m, only 1 degree less ? or more ?
  
  So my questions to the MASA community and especially the marine biologists and divers.
  What is the typical underwater temp where our livestock occurs for winter and summer?
  Do we have to run our tanks at 24 - 26 degrees ?
  Do we have to keep this temp up during winter time?

  ID pls. coral, good, bad ?

  Posted: June 15th, 2010, 10:13am CDT by neo

  Hi,
  got four of these with the leather I bought.
  They 'walk' cause two of them climbed of the leather onto the rocks overnight.
  The other two I removed because they were sitting on the leather itself after two days and made the leather angry.
  What are they ? Good or bad ? seems they like light cause they move to spots where they receive good light and they'r not bothered by flow.
