ph/algae funk control for liquid cooled lights?

[Mr.Sputnik]

I tried bleach, I got white growth on the water jackets when the ph dropped below 8. Now I'm trying enzymes. What do you guys run?

 

[seebobsled]

It is probably calcium / hard water stains. CLR or white vinegar would help.

 

[Mr.Sputnik]

I use CLR to clean the jackets out every other run but this looks like something else besides calcium. I definitely have minerals in my well water so it could be calcium. It seems to stick to the jacket and then flake off like algae. the guys at best coast growers (fresca sol jacket manufacturer) told me a product called chiller rx works better than bleach. We'll see what happens, I tried a septic system enzyme this time so we'll see how it goes.

Oh, and CLR is an acid so it's going to throw the ph way down. The manufacture recommends keeping the ph at 8+ so that's why I didn't try it initially.

I googled chiller RX and website is down. Well water probably could use a filter. Also do you use a water softener, skip it.
I have 4 fresca sols but went to the background. I set them up thinking of using chilled water but found it pricey. Went air cooled now vert bare. If I use them again no chiller just a large rez outside passive cooling.

Can you use a glycol/ water mix and a reservoir instead of the well water?

 

[seebobsled]

Glycol? Rv coolant has a dye in it. Do you?

I recently learned that you should not use bleach to clean toilets stained by hard water because it SETS the hard water stains.

My setup is 12k watts with a 550 gallon reservoir made up of two 275 gallon IBC totes plumbed together and 1hp spa pump. It's a 9 plant recirculating deep water culture system like a DD's setup but liquid cooled and homemade undercurrent system.

 

[Mr.Sputnik]

It's calcium building up on the glass. CLR in the tank fixed it for now but it looks like I'll have to drain it and fill it back up with filtered water. It bubbled like soap in my cooling fountain and you could see the CLR bubbling the calcium away. It took a gallon to do the trick, I might have to get more CLR. We'll see if I get algae with the ph lower than recommended.

passive cooling with a fountain constantly circulating the tank water has lowered my temps quite a bit.

Please explain more !
Ambient temperature, water temperature, and your design of the fountain. Any pictures?

 

[Mr.Sputnik]

Nothing too complicated. There is a 1 1/2" drain on the side. The fountain lowered the temperatures of my liquid cooled lighting reservoir and ambient air temperature of my room by 5-10 degrees. it's just a piece of 2" pvc pipe with a bunch of holes in it and a 75 gallon horse trough. Run by a mag drive 1800 pump. It constantly circulates. bubbles are from the CLR I put in there.

 

[Mr.Sputnik]

Oh it's getting a screen over the top this weekend.

This is an extremely efficient way to shed excess heat and I plan to use it to keep my fish tank cool.

Great thanks.
