The PLC energises an output ( to turn ON the solenoid ) If the solenoid fails it will turn OFF your gravity feed of saltwater to the sump . Don't really think you have a major issue ( sump will only partially fill ) If you really concerned add some more ladder logic Just add a timer onto the sump limit switch ( known fill time plus say 3 minutes ) and use this to generate an alarm output ( sound a siren )

probably needs to be fragged . send me one down via post

Nice Tank Rossco Does that floor need extra strenghting to carry the weight of the tank when filled ? I'm considering a larger setup at some stage , but wondering about the extra weight etc...

It can be done . If you can program a PLC etc... At some stage when I upgrade I may consider this option .

thanks I visited them today . They do get them in so I 'll have to wait . Also bought Joe Juice's and dealt with the Aiptasia .

Next time I'm out the Port - is it OK to visit ? any chance of getting any frag's from you ps . I removed 3 small starfish from my tank tonight ( hopefully no more remain)

Thanks Reef anyone else want to sell me one

Where can I purchase one or two ? Are these available here in NZ ( if not why not ? ) I'm wanting to get rid of Aiptasia naturally rather than ( Joe Juice , kalk etc...) :evil:

Feelers and Mark - fish is a Six-line Wrasse sorry about the photo quality ( I'll figure out how to use the camera eventually ) I wish the fish would freeze while I took their pictures

Here's my effort ( started July 05 ) Note : the little Starfish on the RHS is he friend or foe ? Also I have Aipatasia appearing which I'm really keen to get rid of ( any suggestion for products or methods to elliminate )

you could try pulling it apart again . removed the needle pin wheel assembly .repacked the rubber bush assembly with vaseline and re-assemble . also rubber sponge under the pump could help . contact Deltec for some replacement bushes and damping kit .

costing is dependant on which model you chose . for the basic model including the serial port adapter and reader & Fob about US $60 plus shipping ( very expensive for single items )

http://www.maxim-ic.com/quick_view2.cfm/qv_pk/4379 no it's a little stainless steel module ( about the size of a ten cent piece ) setup required via PC , but then you just place the device whereever you want to measure.

Thought ther maybe some interest in a little device I currently have monitoring the temperture ( note it's not in the tank but above in the overhead sump ) Farenhiet temp range , samples 75.20°F to 77.90°F, 3314 78.80°F to 81.50°F, 3985 82.40°F to 85.10°F, 2455 86.00°F to 88.70°F, 654 89.60°F to 92.30°F, 24 note I only cut a portion of the information DS1921G: 2025400007AB1521 Download at: 14/02/06 18:29:02 Mission State ------------- Mission is in progress Sample rate: 20 minute(s) Roll-Over Enabled: yes Roll-Over Occured: yes Mission Start time: 09/22/2005 20:34 Mission Start delay: 0 minute(s) Mission Samples: 10432 Device total samples: 488895 Temperatures displayed in: (Fahrenheit) High Threshold: 84.2°F Low Threshold: 70.7°F Temperature threshold alarm state: Conditional(none) Alarm(H) Current Real-Time Clock from DS1921: Tuesday 02/14/2006 17:36:10 Current PC Time: Tuesday 02/14/2006 18:30:16 Time Alarm mode: Alarm weekly Alarm Time: Sunday 00:00:00 Alarm Time state: Conditional(yes) Alarm(yes) Temperature Alarms ------------------ Format: [(HIGH/LOW), Time/Date range] HIGH , 11/11/2005 18:34 to 11/12/2005 01:14 HIGH , 11/12/2005 13:34 to 11/12/2005 23:34 HIGH , 12/09/2005 16:14 to 12/10/2005 04:54 HIGH , 12/11/2005 16:14 to 12/12/2005 00:54 HIGH , 12/12/2005 14:54 to 12/13/2005 04:54 HIGH , 12/13/2005 13:14 to 12/14/2005 05:14 HIGH , 12/14/2005 10:54 to 12/15/2005 04:54 HIGH , 12/15/2005 15:14 to 12/15/2005 17:34 HIGH , 12/15/2005 18:54 to 12/15/2005 22:34 HIGH , 12/16/2005 18:54 to 12/17/2005 00:14 HIGH , 01/10/2006 18:34 to 01/11/2006 02:54 HIGH , 01/11/2006 14:54 to 01/12/2006 06:14 Temperature Histogram --------------------- Format: [Temp Range , Count] (Fahrenheit) -40.00°F to -37.30°F, 0 -36.40°F to -33.70°F, 0 -32.80°F to -30.10°F, 0 -29.20°F to -26.50°F, 0 -25.60°F to -22.90°F, 0 -22.00°F to -19.30°F, 0 -18.40°F to -15.70°F, 0 -14.80°F to -12.10°F, 0 -11.20°F to -8.50°F, 0 -7.60°F to -4.90°F, 0 -4.00°F to -1.30°F, 0 -0.40°F to 2.30°F, 0 3.20°F to 5.90°F, 0 6.80°F to 9.50°F, 0 10.40°F to 13.10°F, 0 14.00°F to 16.70°F, 0 17.60°F to 20.30°F, 0 21.20°F to 23.90°F, 0 24.80°F to 27.50°F, 0 28.40°F to 31.10°F, 0 32.00°F to 34.70°F, 0 35.60°F to 38.30°F, 0 39.20°F to 41.90°F, 0 42.80°F to 45.50°F, 0 46.40°F to 49.10°F, 0 50.00°F to 52.70°F, 0 53.60°F to 56.30°F, 0 57.20°F to 59.90°F, 0 60.80°F to 63.50°F, 0 64.40°F to 67.10°F, 0 68.00°F to 70.70°F, 0 71.60°F to 74.30°F, 0 75.20°F to 77.90°F, 3314 78.80°F to 81.50°F, 3985 82.40°F to 85.10°F, 2455 86.00°F to 88.70°F, 654 89.60°F to 92.30°F, 24 93.20°F to 95.90°F, 0 96.80°F to 99.50°F, 0 100.40°F to 103.10°F, 0 104.00°F to 106.70°F, 0 107.60°F to 110.30°F, 0 111.20°F to 113.90°F, 0 114.80°F to 117.50°F, 0 118.40°F to 121.10°F, 0 122.00°F to 124.70°F, 0 125.60°F to 128.30°F, 0 129.20°F to 131.90°F, 0 132.80°F to 135.50°F, 0 136.40°F to 139.10°F, 0 140.00°F to 142.70°F, 0 143.60°F to 146.30°F, 0 147.20°F to 149.90°F, 0 150.80°F to 153.50°F, 0 154.40°F to 157.10°F, 0 158.00°F to 160.70°F, 0 161.60°F to 164.30°F, 0 165.20°F to 167.90°F, 0 168.80°F to 171.50°F, 0 172.40°F to 175.10°F, 0 176.00°F to 178.70°F, 0 179.60°F to 182.30°F, 0 183.20°F to 185.90°F, 0 186.80°F to 189.50°F, 0

I'm currently using Instant Ocean is it possible to use seawater for top up's etc.. or should I stick with what's working for me .

yes, only a little juice per clove . still reckon it work's ( my regal tang had ich and it got better ) it come and goes ( twice so far ) maybe I'll get a rabbit foot as well . ps . all my fish eat the mysis shrimp soaked in garlic juice ( in fact they love it )

Feed him garlic juice with his food ( every feeding time ) Use fresh Garlic clove ( mix with his food eg mysis shrimp ) it a miracle ( he can only get better now )

No , I'm Saltwater in a AR620T .

Installation was acording to Aquaone instructions ( white filter- fine on bottom and then noodles and black filter - coarse on top ) I'm also running a Deltec skimmer fitted through the filter box - I've already removed the filter etc .. when I installed the skimmer - didn't notice any gunk ( just noodle dust ) . No problem with air bubbles etc.. I get them ocassionally when the skimmer's working ( just after feed time )

I put the white on the bottom then the noodles and then the black on the top . I heard some people have put the noodles on the bottom then the white with the black on the top ( purely for ease of changing the filter wool out )

I have to agree with Suphew . Cleaner shrimp will do the trick ( you need at least 2 ) works for me as well . make sure you feed that garlic juice ( all the time )

Try getting a garlic clove ( fresh ) . crush the clove and use the juice only mix with mysis shrimp . soak it an hour or two before feeding . Worked with my Regal Tang ( cleaner shrimp also helped )

I'm from the same area ( Pukekohe ) . I get all my water from my mates place at Puni ( bore water straight from the 3rd substrate level 80 ft down ) his place is about 100 metres away from the Waikato river .

I'm actually running carbon at the moment . How often should I be replacing it ?
