Greg's 75g

I think I have the GHA under control
I plucked all I could grab, then scrubbed everything in-tank with a nail brush and toothbrushes. Then I turkey basted everything until it all stayed clear - all the while the Vortechs were on full blast and everything eventually went into the socks
Then I did my WC
All that took me over 3 hours
A week later and it's no longer growing like gangbusters so all I have to do now is stay ahead of it until it dies off

I finally completed my sump room exhaust plan;
For 2 years I've been thinking about how to get the warm, humid air out
I first thought about using a bathroom exhaust fan with a Humidistat and an AC controller. By the time I added up all the parts I decided it was too costly and that's why it's taken 2 years to finalize the job
A rough build cost for a high flow fan with a low sones (noise) rating, 2 controllers and all the relays involved, I was looking at over $250

The chiller fills the room with hot air causing me to need to run the AC or risk the chiller losing efficiency in an overheated room. But there's nowhere for the humidity and salt/skimmer smell to go with the door closed
I decided to run sump fans to cut down on chiller usage and noticed a big improvement in both chiller runtime and room temp, but increased room humidity with sump evaporation
So I thought about using a fan and dryer vent to take room air outside when the sump fans run and it hit me ! I can do the same thing with the chiller exhaust !!!
Results are an office/sump room that's now the same temp as the house vs 2-5 degrees hotter

I bought a dryer vent kit, a second stand-alone vent, a cheap storage tote and a powersupply big enough for the sump/exhaust fans. Total cost was under $65
I already had on hand 5 fans - 4 for the sump system and one for the chiller exhaust. These were about $50. Plus a PC fan adapter that may have been $10, and a powersupply for the chiller fan setup that was $15. So, for less than $135 I'm done
The PC fans are also quieter than any bathroom fan and I hardly hear them
Yes it's fugly, but it's just my office ...

The sump fans turn on just 2 tenths of a degree before the chiller, but it's enough to delay it coming on by hours
I'm using more ATO water but no biggie
Sump fans



Storage tote


Storage tote with one end cut off and 110CFM PC fan. This allows the fan to draw room air instead of fighting the chiller's fan


Back of chiller where tote mounts


Storage tote with fan and duct adapter
I cut the adapter in half and trimmed the pieces down to 3 inches
One piece for the vent and the other for the back of the tote
You'll see where I cut the end of the adapter so I had a way to tape it in place

Here you see how the fans are strong enough to open the dampers
