i have a few issues i'd like to hear thoughts on....

first, the harmonic distortion and vibration in this room are killing me. the only real changes to this room since we moved in is a couch, an antique writer's desk, two huge paintings, and a carpet that covers a good 15x15 area in the center of the room. other than that the room nearly empty of sound absorbers. just one big echo chamber.

its not the sound of moving water that bothers me. at first i felt that it was the tank using alot of electricity. and that current was bothering me.
:D it is not. as it turns out i use way way less electricity here than i did in nyc. go figure. my brother's band came through town recently and we had a long conversation about what it was that was bothering me. the harmonic distortion.

not only is this a drone on the ears, but it happens to be the key of Bflat. which in it's self is a drone on the ear.

one thought was a rubber pad between the stand and floor.
TONS of weight, not easy to do.
another was between the sump and bottom of the stand. not to hard, could be effective.
the best solution we saw would be to put an absorber of some kind between the pumps and the bottom of the sump tank. and insulate the walls of the stand to absorb sound.

but what that will not leach anything foreign into the tank....

next gripe is, the return side of this tank sucks it's cavity dry in 34hr 24(28)min. (aprox 3.75-4 gallon and consistent!! :) ) right now i have a MAG 7 throttled back to a little less than half way and i have noticed a much much slower flow through the sump..... although i estimate the time through the water in the return section to increase by no more than a few hours at best.

fixes? i have a MAG 5 that i could put in there, but i feel that is not really the answer. i can't imagine that would do much more than allow me to open the valve a little more, but still flow the amount of water....

i guess i am looking for modifications to the tank setup that it came with.

other issues become auto top-off. i've done the research, i know how much it will cost to do it, and do it right. i just don't have the money to throw at it right now.

my thought for an upcoming trip is a 5 gallon on a stool with a simple bulkhead and valve dripping into the sump. 5 gallon on the floor or in the sump won't kill anything...... but i also figure that would give intervals of three (serious stretch, of four) days without having someone look in on the tank. which could work. i am gone for an estimated 155 hours.

anyway, here is a photo of the room empty prior to move in,
(nearly the same state of decoration, just a few things mentioned)
(and the shelves in that corner have been removed)

and the sump tank in question,

thanks!

right off the bat, you could try a pair of mousepads(the neoprene ones) - put one under each one of your pumps - that could be enough to lessen the vibrations - if that doesnt work, a larger sheet of neoprene under the entire sump might have to be installed(I think the mouse pads will be enough- it was on my old sump, and I had a Mag 9.5 and a 12 running)

the next thing, you can get foam board(its readily available in any arts and crafts shop)and line the cabinet with it(double sided tape is more than enough to hold it in place if needed)
you can add to it further, with acoustic matting for cars- it has an adhesive backing to it, and can be cut to fit as well(any car stereo installation shop would carry it)
another alternative would be the "egg crate foam" they use for camera cases, and for soundproofing(dunno how available it is near you- some music stores(esp. stores that sell DJ equipment) carry it in large quanities

Just remember, after insulating the cabinet, you might need to place a small fan to keep temps low(put a mouse pad under the fan too) as I dont know how well your sump is ventilated - you'll still likely have a bit of droning(you tank is after all sitting on barewood), but hopefully this will lower it to a more acceptable level for ya.

On the drip plan, you can find cheap used medical dosers on ebay that do the trick.

See eBay item #270287835659

I just bought one from this seller (should be arriving today actually..) - I've had excellent communication with them and they have a 100% feedback rating.

The pump in that listing doses up to 295 ml/hr.

From onlineconversion.com:
295 milliliter = 0.077 930 755 446 gallon [US, liquid]

If you work that out to its conclusion, its not enough to keep up with your current demand, but 2 of those dosers certainly would.

Another way to possibly make one unit work out for you though (and maybe help your noise issue) is to lower the volume of water passing through your sump by reducing your return pump size. (Less water moving through your overflow can greatly lower your evap rate..) - This may have benefits as well in terms of your noise issue.

Considering you have a consistent rate of evap, your environmental conditions are probably very consistent. - A gravity dripper is not consistent, a dosing pump is. ;)

Try the mouse pads for the noise, they normally make a big difference.

On the top off, get a 5 gallon container and a float valve, put the float valve in the sump and feed it from the 5 gallon container. It will keep the sump full of water, and is pretty reliable, but it does not have any type of a backup system. Less expensive than a dosing pump and easier to setup

mouse pads huh?
just any ol mouse pad?
made out of any specific materials?
anything to avoid?

----

i can do it gravity fed right?. this way i don't need a pump....
its only a temp fix until i have the extra funds to set one up properly.

The solid neoprene mouse pads work well, or you can get silicone bake ware, it will work very well also.
Don't get a mouse pad that has the cloth top that is glued on.

Another thing you can use that has worked very well under my floor located external pumps is rubber shelf lining. I guess it's used to keep dishes, plates from sliding around inside your cabinets. Its kind of a rubber mesh that you can actually fold to make as thick a pad as you want under each pump. Very inexpensive too. You can find it at WalMart or similar store.

Yeah, gravity feeds are ok.. - I've gotten by with them fine for getting away for a few days but they never worked out for me too well when stepping out for a week or more. They have a tendency to slow or even stop as the reservoir empties and less pressure is on the crimp.
