Re: [Killietalk] Pump for recirculation system

OH...I forgot to also mention this lil nuance w//recirculation systems &
fluidized beds...

1) fluidized beds allegedly use up O2 like a mutha, I'd make sure you put in
a lot of "Splash" somewhere in your system (esp the outlets) or use a
trickle tower in tandem

2) I wouldn't dismantle my old air system just yet...It dawned on me that
during a power failure, it's a lot more efficient to run my Jehmco's 60
outlet, 74Watt Linear piston than the 7-8ea 60Watt+ water pumps...in that
same vein, using your old sponge filters in the sump (as a biological media)
might be a lifesaver for those inevitable springtime 24-48hr power
outages....it would be a simple matter to pull out those nice & wet (and
already bacteria charged) old sponges, hook up the hardware and save the
fish

...and BTW, I've been thinking there is a way to design/modify your
recirculating system so you can switch back to air if need be...you could
put a union connector followed by a tee right after you pump...during a
power failure, all you would have to do is disconnect the pump, cap that
end, uncap the "tee", and hook up your airpump...heck the valves and line is
already there...add those "pre-charged" sponge filters from the sump and
voila'

Dear FishFolk,

I am re-building my fishroom and have all the parts for a fully automated
flow through system. However, the Tulsa water is fairly hard 80 - 120 ppm.
For some of my fish I cut it 50% with DI water and I also like to have salt
in my water. I keep nothos and I like the longevity it gives to bbs. I can
set things up as a semi-automated system as I have filters as well as DI and
carbon cartridges to change my tapwater into reasonable water good water. 

I am looking for advice on two things:

1.  A pump for a recirculation system one that I can valve down to 15 psi
for my drip valves. The head would be about 6-7 feet.

2.   Some kind of timed drip system that I merge with my incoming water to
add salt (or saline) at a measured amount to reach 1/2 - 1 teaspoon per
gallon. 

3. Any way to merge pure DI water with the automated system. I bought a $30
automated timer and an inline heater to bring my tapwater up reasonable
conditions. 


I may end up with a re-circulating system on a 30 gallong sump that I shut
down and drain 20 gallons twice a week then manually add clean water. I have
already figured out how to do this with my existing equipment.

This would allow me to add a fluidized bed filter to the re-circulating
system. I have them on two large tanks and although it is a pain to set them
up and they can be finicky and clog, they are worth it. On a 20 gallon
brackish tank every single species I've had in the tank has spawned. This
includes bumblebee gobies, rainbowfish, mystery snails and livebearing
halfbeaks, among others.

Thanks for the advice,

Earl
