  Profilux Doser Issue

  Posted: November 17th, 2011, 9:09am CST by mariusmeyer

  I have the quad doser with built in controller, and last night I realised that the one pump was not dosing via the controllers dosing program. I can run the pump manually via the push button but thats it.
  
  Just wanting to find out if anyone had a similar issue and if there is a quick fix without sending it in for repairs.

  Photo's and description/list of items for sale:

  Unit most probably 18 months old but used for 6. I bought this unit a year ago but never used it. Only thing I used from this unit is the halide globes. Comes with mounting feet and will fit on tanks up to 900 long. No hanging kit included as I never got the cables from previous owner. Should be possible to get the suspension cables from a store where i got the original replacement UV shields. Comes with a spare original UV glass shield.
  
  Unit has 2 X 21W T5 on the sides. Would work very well with 20K globes as they are nice and crisp. NO HALIDE GLOBES included as I used the globes in my aqua-medic pendants.
  
  Dimensions: 900L X 315W X 80H.
  
  T5 and Halides work on separate power cords.
  
  Previous owner used it on a SPS dominated 900 X 900 X 700 cube.
  
  New this unit retails for R5500.
  
  Asking R1500.

  Tempered Glass Needed

  Posted: April 19th, 2011, 11:09am CDT by mariusmeyer

  Hey guys.
  
  Anyone know where I can get a small piece of tempered glass? I broke the glass on my one MH light unit and need to replace it. Will most probably be a custom size as its a dymax light unit.
  
  Thanks

  Blackout to combat cyano?

  Posted: January 16th, 2011, 1:32pm CST by mariusmeyer

  I have quite a lot of cyano at the moment. It is all over the rocks etc and is starting to grow on the corals as well. I have read that a 3 day blackout can be used to get rid of it since the bacteria does not get any light to photosynthesize. Would the corals be ok with this? I have mainly mushrooms, zoas, a picushion, frogspawn, ancora coral, plate and doughnut coral. Only have 1 SPS in there, its a green slimer.
  
  I dont want to go the chemical route so i want to start with this first. Will skim wet during this period to get rid of the bacteria as they die. I will be doing a 25% water change before and then after as well.
  
  What do you guys think? Could this work and will the corals be ok? I want to do a total blackout with black sheeting.

  Need help finding inverter.

  Posted: December 21st, 2010, 12:51pm CST by mariusmeyer

  Hey guys.
  
  I need your help in finding another inverter for my backup solution. I am looking for a 12V pure sinewave inverter that has a built in auto transfer switch. What brands do you know of and who can I contact. I only want to run my 145W lifetech return pump. It needs to be able to handle the extra startup load of the pump which some people claim can be 6-8 times higher than the rated power. So that makes it a 1000W inverter roughly.
  
  I have dealt with Current Automation in Kya Sands recently and I am not impressed with their backup service. So I am looking for another supplier.
  
  Thanks

  Pump startup current draw

  Posted: October 29th, 2010, 10:09am CDT by mariusmeyer

  Hey guys.
  
  I am looking for some more advice from the electrical guys. How many times more would the startup load be with a submersible pump than its normal rated wattage. I have a lifeteck AP4660 which takes 145W. What type of startup load are we looking at.
  
  This is apparently important when choosing in inverter according to a salesman that I am having issues with. He says a 145W pump can not run off of a 350W inverter with a surge rating of 700W since the startup load of the pump is around 6 times more than the normal rated wattage.
  
  Any way how I can test the startup load of a pump?

  One for the sparkies

  Posted: September 13th, 2010, 11:27am CDT by mariusmeyer

  I need some input/explanation here please.
  
  I finally connected my battery backup and tested it to see how long it will keep my return pump running.
  
  This is what I have. 145W return pump, 102AH deep cycle battery with built in state of charge indicator Green for 70% and up, black when less than 70%, new and fully charged. Inverter is pure sine with an efficiency of 86%. 3 stage charger.
  
  So according to my calculations the pump will draw 14.05A from the battery. (145W/0.86%)/12V
  
  For a full discharge of the battery it would be 102AH/14.05A = 7.25 Hours or 7hours:15mins.
  
  I monitored the battery voltage throughout the entire time (I know it is not an accurate estimate of state of charge) to see where it is. The battery started off at 12.4/12.5V. After 7 hours of running the pump the voltage was down to 11.9V and the state of charge indicator was still green! How can this be? I thought that the state of charge indicator is not working as it should. So I switched the pump back to mains and let the battery recharge. I expected it to recharge for around 16-24hours as it should have been close to dead according to my calculations. Yet after 6.5hours, the battery charger indicated that it was in float charging mode.
  
  So was my calculation on running time incorrect? Is my pump drawing that much less power? Or do I have a super battery?

  Maximising battery time

  Posted: September 12th, 2010, 9:18pm CDT by mariusmeyer

  I've been thinking since I hooked my return up to the inverter. Would it be ok to run the return for 30mins and then off for 30mins. The return is about 3000LPH after headloss and total volume is 600L. Very low bioload, only a few corals.
  
  With this on-off routine you can effectively double the backup time. And 3000LPH for 30mins means a total turnover of 2.5X during on time. If we could leave it on for shorter or off for longer then you get even more time out of the battery.
  
  Any thoughts on this?

  New MH globe needed. Which one?

  Posted: September 3rd, 2010, 12:20pm CDT by mariusmeyer

  Hey guys. My one 250W globe went 2 days ago and I need to replace it. The following is a pic of what colour these globes made my tank.
  
  
  They are the 20K Dymax globes. I like the crisp white colour that they give off and the coral colour reproduction is also very nice. But I am not sure how good they are in terms of growth.
  
  How would the BLV 20K compare this colour wise. I know Adee runs them and he gets very good growth as well. Does anyone have a pic of a tank with the Aquamedic 16K globe? Also, if I go the 20K BLV route and it is too blue, how many T5 54W globes would it take to break that down to a crisper colour? I know clear cut answers is not easy so I am looking for rounded answers.

  Auto transfer switch

  Posted: August 31st, 2010, 4:39pm CDT by mariusmeyer

  I have another problem with my backup solution.
  
  Since my battery was draining while I hooked my return pump to the battery (which was connected to a charger), I thought there must be a problem. Phoned the guys today and they say that the way I connected everything will not work for my application.
  
  Apparently if the inverter does not have a built in transfer switch, the battery will get damaged since it will be getting a constant high voltage from the charger. No I cant go and spend another 4K on a inverter so I want to know if there are ways of adding a separate transfer switch.
  
  Any sparkies out there in the know who can assist. Does everyone else have a inverter with built in transfer switch?

  Prefer collection, can deliver to PTA over weekends, Shipping at buyers expense (+- R150)

  Photo's and description/list of items for sale:

  Guys, I am selling my Reef Octopus Waterblaster HY-7000W. It is about 4 weeks old, used for 3 weeks by the previous owner and for about 20mins by me.
  
  Yes, I only used for for 20 minutes. I wanted to use it as my return as well as to power the scrubber. It has a 32mm pipe on the outlet, I also include a reducer to normal 25mm (black fitting on right in first pic). The flow out of this pump is great. Reason I am selling, it was sort of an impulse buy and only realized after that my big lifetech pump could do the same job. I paid R2100 so that is what I am selling it for. New this pump is just over R3000.
  
  
  
  
  
  Flow Chart
  

  Notes:

  Ideal pump to use to power multiple things (scrubber, return etc.). Can be used as internal or external. Power consumption is great at 88W. Does 7000LPH. Head height is 3.6m. Flowchart is attached.
  
  This is a great price on a basically new pump.
  
  R2100 in case you missed the price at the top.

  Dosing pumps

  Posted: July 2nd, 2010, 4:22pm CDT by mariusmeyer

  What is your opinion on dosing pumps. Are they worth the money or just a luxury? I'm looking at the aqua medic quadro. Any other brands worth looking at?

  Is this possible or not?

  Posted: April 20th, 2010, 3:01pm CDT by mariusmeyer

  If I wanted to keep corals in a tank for 5 weeks while waiting for my big tank to cycle, do I need a complete filtration system running? So its like a QT for corals. The corals dont add much to a bioload so a bag of purigen in a HOB filter should be enough to absorb any nutrients. They are all corals that dont need special feeding so lights will be enough to keep them alve.
  
  What do you guys reckon?

  Gatvol with skimmers

  Posted: April 12th, 2010, 9:38pm CDT by mariusmeyer

  I am getting very gatvol with skimmers now. I exchanged my OCTX200 internal for a bubble blaster 2000 due to the sicce pump making a huge noise as the pinwheel mulches up the bubbles. Got the bubble blaster today as it is supposed to be super silent and hooked it all up, just to find a freaking humming sound that is lowder than say 3 air pumps running at the same time. The mulching of the bubbles are dead quiet but the humming is terrible. It is quite a bit louder than my cheap lifetech return pump that pumps more than twice the amount of water.
  
  I can not take i anymore. You spend close to R5000 on a skimmer that is supposed to be quiet and then you get the humming? Am I missing something here or am I wanting unrealistically low noise levels from my equipment?
  
  Is internal skimmers noisier than external ones? Cause I listened to the external bubble blaster at idol marine and I had to put my ear right next to the 7000LPH pump to hear if it was on. So why is my 2000LPH noisier?
  
  Sorry for the rant but I'm running out of ideas here. Maybe I should just go skimmerless and build a mother of an algae scrubber.

  Fish from Idol

  Posted: April 12th, 2010, 8:56am CDT by mariusmeyer

  Hey Guys.
  
  I vaguely remember something about Idol marine keeping their fish only tanks at a lower salinity, so how do you acclimate these fish? Do you keep them in a separate holding tank and slowly raise the salinity by 0.002 per day? I think the shops water is at 1.017 and my tank is sitting at 1.025
  
  Please advise.
