Thanks for the help, I got my paws on a 24V solenoid valve that can handle the water system's pressure, and the setup work like a charm. If I can only figure out a safety in the case that the solenoid gets stuck open!? Any takers???....

Thanks for the warnings seven ephors... I am not 100% comfortable myself with the 220V being so close to water so I have taken all necessary precautions (on the floaters, I added extra insulation with blobs of silicone, splash guards etc...) The solenoid is indeed pressure rated for the...

I finaly managed to get my paws ..errr.... fins.... errr.... hands on the 220V floaters I was looking for. :D Next obstacle is to control one solenoid valve (when idle it restricts water through it) with two floaters. I need to open the solenoid (and allow water through) when either one, or...

fungia thanks for the input on ultralife. It's rather pricey (trying to cut all corners w/out sacrifices for my future inhabitants) so I think I will resort to a DIY setup. Will probably use a plastic floater and gravity feed RO water for top-offs. For controling the two pumps I am thinking...

:oops: mistake duly noted!

CrisRD thanks for all your help. OK, I have redeisgned the sump to something simpler, aiming in two directions: 1) Slow down the water current through the regugium 2) Control light (all plexiglass dividers, baffles etc are dark blue now) 3) Provide space and easy access to skimmer(s) 4)...

Hi all, While still planning things for my new tank, I am trying to solve a few issues. 1) I need to control a small powerhead that will top-off the sump with RO/DI water (both turning it on when water level is too low and shuting it down when level is too high) 2) Also I need shut-off the...

Thanks for taking the time Chris! Great input. I think I have read every piece of html that Melev has put up on his site, and I admit I am considering simplifying my design a bit in order to achieve a slower flow through the refugium as you suggested. Originally I had designed two EHEIM 1262...

Hi there Chris! Yeah I forgot the dimensions (all in centimeters) 70 (L) X 50 (W) X 50 (H) so it will house approx. 30G... Obviously, I can add some height (another 15-20 cm) to get another 12-25G if it's needed but I'd rather not if I can get away with this size. Can you comment on my...

Hi all, Great place you got here and thanks for all the help I have found around. I need to apologize since this, my opening post is such a lengthy one. I'm an old NYer that now lives in Athens-Greece, and I've been keeping tropical tanks and african cichlid tanks for the past 6-7 years. I...
