Benefit to res chiller besides root rot?

    Danner Mag Drive pumps are really good, but expensive. I think that's what you're going to ultimately find. It's gonna cost ya :smile:

    I'm using the same eco pump that I bought 4-5 years ago and I think it's 650 gph that works well with my home made chiller but I've set mine up using delta t and super heat. What's the flow rate for your chiller?

    I am confused about the flow ratings on the aquarium chillers though, when I set up a geo unit I'm running 1.5-2.5 gpm per ton their 2-6 tons lol.

    Thanks! I just ordered a Danner 1200gph, well see how much this cuts down on the heat.

    Nice work! @JSB99 I am going to chime in on the pumps too.

    Eco pumps are made by danner.

    I have a ach10 1/4 hp hydrofarms chiller. What size pump is would be a good one to run?

    Btw, you have got me thinking about run my res out of the tent as well. This is where I will be running my lines through. I refuse to cut the tent lol.

    Btw, I have 2 new carbon filters and my whole basement smells like weed!:)

    Didn't know that. I'll have to keep that in mind when I replace mine.

    Yep, you can certainly do that. A few things to think about:
    • You'll lose some pressure with extra pipes and curves. Instead of pvc elbows, think of using pvc sweeps, which are curved elbows. Consider a larger pump for the loss in pressure. Consider using flexible tubing instead of rigged PVC, where you can, which might make it easier to do bends.
    • Consider using two ports instead of a single for both feed and return. This can help keep excess pipes and tubing out of the tent, where temps will be higher, ultimately warming up your water.
    • I spent a lot of time trying to avoid cutting my tent. After deciding to do just that, all my issues of how to route the pipes through tent openings were solved. If you get stuck, cutting your tent isn't a big deal.
    • There are a lot of benefits to having your reservoir outside the tent. So, if you have the room, go for it.
    These are just some things to consider :)

    Another advantage to an external reservoir is that you can check your levels, add nutes, balance water, etc...without having to open your tent. The less your tent is open, the less chance you'll allow bugs to invade your grow

    The only way you are going past 2gpW is using vertical tunnels and training plants around the sides with a central bulb hanging bare.

    I mentioned this earlier, but I meant ".7gr/watt", not "7gr/watt"

    I would expect that a larger pump would create more heat. I wonder if a PC fan blowing on the pump would help.

    If the pump is getting warm, and warming the water, then I would think keeping the pump cooler would ultimately translate to the water. Removing standing heat might also help cool any pipes around the pump.

    Just brainstorming here :)

    The pump I am using now is 2100gph.

    Ah, gotcha! Missed that part.

    Let us know how that Danner works. I really want one! I'm with you on the actual pressure of the cheaper pumps. I really doubt my 400gph is just that. Maybe if there aren't any changes in elevation, and there are no bottlenecks in the piping. I bet a Danner 1000gph is way more powerful than an Active Aqua 1000gph pump!

    Thats the setup heath built. Was essentially a spiral nft system that was 2 levels tall

    Actually I think he put paddles that took up half the pipe to make a shallow water culture sustem

    Rated for 70-320 GPH which is a huge spread so I would pick mid way, the slower the flow the colder the outlet water temp.

    I've said this before, but I honestly think that as long as your RDWC water cools down to the mid 60s at night you're fine- and that having it rise during the day is actually beneficial for growth.

    It stays at 65-66 during lights off and hasn't gone about 70 with lights on, so I should be good to go.
