sump and refugium in room with hvac equip
 

I was planning on putting my sump (55 gal) and refugium (125 gal) in a back room that also has my hot water heater and furnace. I have heard rust is a big issue with this. Would it be OK with a dehumidifier or will the salt still get everything?

I would think heat and carbon dioxide would be bigger issues for the sump then the salt rusting out the heater and furnace equipment

I have the same: I don't think it should be a short term problem. I also have a washer-drier in there that really humidify the place, and that's not damaged the unit, so we'll see---but unlike with crashing surf on a beach, evaporation leaves most of our salt in the sump, and aeration is done with the skimmer...again, a closed box. So I don't think we send as much salt into the air.

very true---but I am still looking at the adequacy of the ventilation in a small area like that. It has the potential to create a co2 problem.. Most furnaces etc are not vented to the outside of the home. For us northern guys it presents a real problem in the winter time--and I have my sump and fuge in the basement also.

Heat or cold should not be an issue. For some reason my basement is always the same temp (all underground, no walkout). My testing once I get it all plumbed up and filled will be the final test if that is correct.

The co2 problem? Is that an issue because my units will put off co2 and that will be taken in by the water? I used to have many 20 longs in the back room when I did breeding for freshwater, never seemed to be an issue. Let me know if the chemistry for salt makes co2 a bigger issue. I also have everything vented with my units out via pvc, all high efficiency stuff.

Glad to hear others dont have issue with rust, I was going to have to scrap the entire plans for where the tank was going to go and have only a 55 gallon sump/refug under the tank.

Do you think it would be a long term issue? I think it sounds right when you said that salt does not evaporate in the air like waves on a beach. What do they mean when they say "salt creep"?

Salt creep is the short-range evap on lines and tank edges, usually on the tank rim. It really doesn't get too much further. Swipe a wet finger across your wall some distance away from your sump. Taste it. If there's salt, that's a problem, but if not, it's not in the air.

I have this set up as well. I am noticing green corrosion on my water lines in the area in close proximity to my sump. I don't think I've had any issues regarding CO2.

Unless you have a space heater that says "no venting required" the only furnace/ hot water heater that does not need venting is electric. ALL others need to be vented to prevent the occupants of the home from getting carbon monoxide poisioning. if the copper tubing is green near the fittings it could be from too much flux when it was assembled or a water leak that was addressed and the water caused the tube to oxidize.

The green on my copper water lines is along an open run of several feet with no fittings, no previous leakage. I see this only in the area immediately near my sump. Other visible copper lines in the adjacent and open to utility room/storage area do not have the green on them.

sorry I should have added intaking---mine caused a big co2 problem until I opened a window last summer. Most furnaces do alot more recirculating of air then drawing in new air from the outside. This is esp true when running central air.

be careful you are not getting "post nasal drip":D from those pipes back into the sump and fuge. esp if they are copper. I had to insulate mine over the sump area.

No doubt, Unless there is a fresh air intake, all they do is recirc.
