thank you for your input! :D the "sand" I'm talking about is graded from 3 to 6mm in size. I've tested it in vinegar - no visible reaction, then I've washed some more "sand" placed with distilled water and…"
"Hi Xpim...you might want to forgo the sand. The International Organization for Standards (ISO 14688) grades sand into fine, medium, and coarse (coarse being 0.64mm to 2mm). In the US they sub-divide these 3 grades into 5 grades (the largest particle…"
"If you are going to use the rebar keep it out of the system. the rebar will last longer and rust less. using the plants as a cover for your fish tank sounds good if it is a small tank but if it is bigger that 4x4 them you have to think about…"
hydrocorn is just ugly hydroton. Nice! I did not know this thing... I'll try to find it... nearly half the growbeds are going to be a coarse sand/pebbles that are used on water well drilling... clay aggregate are still on the list...
"They may very likely be 201 grade stainless steel (developed to be a cheaper stainless steel alternative to the 301 and 304 grades. So it's super skimpy on the Nickel). Many less expensive SS items (like non-galv hose clamps) use this…"
"There is a chemical compound (difloroethane) used in some brands of duct tape (not all), and that chemical is toxic to fish at certain concentrations. Sorta how potassium chloride (KCl) is on the one hand used to execute prisoners on death…"
"The 2-1 refers to the Bernoulli funnel on top of the standpipe. When you think about it the faster the standpipe fills with water the faster the siphon kicks in. So the bigger the funnel the more the water flooding over it and the faster it starts.…"
I would go inverter and stick to pond pumps. Might need another solar panel but I think it would raise the reliability factor 10 fold. Like Alex said bilge pumps have a low duty cycle meaning time on/time vs off/time BUT in a timed flood…"
"Thanks for the response!
Are you saying 2-1 bell to drain diameter ratio? The IBC pics look like its 3" to 1"? WHat reducer sizez have you had the best luck with, are there any basic principles youve found? And Im using 18"…"
"How about a "hinged" screen that allows them into your sump for rearing but does not allow them back in the other way? This is assuming you want them in your sump?
Vlad, didn't I read somewhere that duct tape has is poisonous to fish?"
"A quick note on the snorkel or hole that Rob refers to: I use neither. All the air you could ever need to "break" siphon will come thru the routed bell bottom slots and back up the stand pipe. Just be sure and have an air gap or vent after…"
"Hey Hunter, what are you looking for a supercharger? I agree, if it is working you are all set. Personally I like the 2-1 Affnan design and having sold about 500 worldwide with great 100% positive feedback I have no reason to change my design as…"
"Elevation is a relative term. I am spreading my gravity power among about 10 IBC GBs in two rows of 5 so I knew I needed plenty of GP. (gravity power; did I just coin a new AP abbreviation?) In Jeff's case you are not spreading it out as much…"
