automatic water change

iced98lx said:
As a note, I found this thread: http://www.reefcentral.com/forums/showthread.php?t=2068147 which showed a PVC based tubing holders while I was searching for probe/dosing line holders. Being a cheap you know who I employed it for my setup, though the locations are temporary the clamps work excellently:



I felt the acrylic options I found weren't as secure and much more expensive (NOT FREE).

I've changed out ~100 gallons of water in the last two week (been a little more aggressive to catch up on nitrates from initial cycle) and everything has worked great with no salinity shifts. My coral are really responding (easy to say that as I put up big new lights and reduced Nitrates significantly) but that leads me to an observation:

this is the best thing I've ever done for my tank.

I really believe that should I be willing to invest the water and salt mix to keep this running it will significantly reduce my heartache in getting my big tank growing coral and keeping fish without major problems. I feed heavy now, let the skimmer work and let the water changes do the rest. I love it and so do my coral and fish. Thank you all for the ideas and help.

I love that idea!!!!! Curious why you are not using the Stenner provided strainer/weights?

And yes: this is the best thing I have done to my tank in more than a decade!!:hammer:
 
Less chance of temp swings I guess and the old reefer mentality of good things happen slowly. Looking to do about a gallon a night.

Got it, I run mine for 5-10 gallons at at a time with #5 tubing and I don't see any swing, but I don't know how much water volume you have (I have about 200 gallons total). Certainly there isn't an ounce of harm doing it slower.

I have a stenner strainer/weight in the new salt water tank, I guess I was intending to add one to the suction side of the sump but have not as of yet. I really don't need to with these hose holders, but I may anyway for the straining part. I think I'll always leave the new salt water return hose out of water so I can visually verify it's pumping.
 
I actually built high and low switches for all 3 brutes of mine. My one brute for top off fills and empties in cycles ohhhh yea loving that.

Then I have the other two brutes one atop the other. for mixing and mixed SW. Which the upper brute will feed the lower after mixed as it is used. via float valve backed by switch/solenoid fail safe.

Report here of my new set up AWC
I hooked my drained tube (for draining old tank water ) the white tube. in my overflow of Display Tank ;

And set the inlet tube (for filling New salt water ) at the sump ；

My Peristaltic pump ( Watson - Marlow 323S) set at my Balcony , below picture beside another one for my calcium reactor;

08379122445dcdcc7053e128debdedcc.jpg


Since it is double pump head so the draining and the filling at the same time at the same volume , but because my sump limited spaces only closely can filled 16 liters (abt. 4 gal) as I turn off the returning pump while changing water , I think this volume is way low for my total water volume of 420 liters ( abt 105 gal), so my questions is;

Should I make weekly 4 % WC? Or daily or every other day or every 2 weeks?

Or

Should I just let the returning pump running while changing water ? But I am worried that I may Drained new salt water as well simultaneously !

It took about 1 hours and 25 minutes to change water at 200 RPM with tube # 16 . I feel the water change speed is too slow , may be I will double the speed at 400 rpm to reduced time to 45 minutes .

Hope to hear your advise and recommendation .

Cheers,


MD

My pumps run every hour I kind of like that idea.

Not sure if you'll find many that are familiar with your units. I bet if you showed it to my wife shed try to swipe her credit card through it. Does it let you program times?
 
I wonder your Pumps that run one hour change how much volume of water?

My units are not so much familiar to most of the people hee as it is made in England unlike mostly use Cole Palmer pumps . No it does not allowed me to program times .
 
I change 1% per day (30% per month).

Only thing you need to program times is a digital timer. Preferably with 1 minute increments.
 
 
Thanks , I also have a similar one ;

But I wonder my pumps can go on off by this timer , as my Watson-Marlow 323S has its switch at the back and then on the front panel it has the start and stop button like this ;

c31c940b421803011f17cbac9d4633ef.jpg


In case I turn the switch on and then I press the start button and hooked to the timer and if timer goes off and when it on again , I wonder my pumps setting will stay at the earlier mode or It need to be press start every time ?

automatic water change

Question here;

My return pump : Eheim Compact 5000+
Flow rate : 5,000 liters / hour or 83.33 ml / min

If I use L/S tube # 17 with a flow rate of 3.6 ml / min. Then Roughly I can run my Watson - Marlow 323S at 30 rpm so to give 108 ml / min which if this is the case then I can draw old tank water and feed new salt water without needing to turn off return pump and this way may also be more sure that no new salt water may be also drained out at the same time as mostly worries in so called continuous changing water ?

Hope to hear your comment .

MD

Thanks , this is also one way of commenting .

Will take a look at the said page. I have read Randy's article at the front page of this thread , it a very long yet useful articles indeed .

But the basic of my questions is seeking a discussion on possible NSW being drained at the same time , arithmetically based on the said flow rate of my return pumps vs my peristaltic pump's flow rate.

Anyway , Thanks and cheers ,

I believe the article answers your question although not specifically to your pump rate but in general. Happy Reefing.
