Folks, if you've recently upgraded or renewed your annual club membership but it's still not active, please reach out to the BOD or a moderator. The PayPal system has a slight bug which it doesn't allow it to activate the account on it's own.
John, this is yours if it meets your needs....
I believe flex for 1 inch and for 1 1/2 inch standard fittings. This pic is of the stuff labeled 1 1/8, but that's a standard 1 inch PVC fitting on the end. You can see that it makes pretty tight turns, how it's rolled up in the box. Maybe 15-...
Nitrite is an issue with freshwater fish, but saltwater, it really is of little concern. It would have to be through the roof before it became a problem.
I was with Edwin today and he mentioned this post and felt compelled to reply. Vinegar is an odd little acid (acetic acid) that has the ability to permeate plastic. The vinegar is getting to the magnet and causing it to start to rust (oxidize), and in the process swell....eventually breaking...
There's a six foot non-reef ready tank on the curb on Rhodes Street in Sayreville....might be a 180. If wanted, need to get it NOW because it's out there for big pickup.
Two videos for you....
Getting air out:
Rebuilding valve....take note of freeze and wear comments. You might wish to first take your valve apart to see if anything is obvious before ordering a kit:
Backflows don't hum, they typically chatter....more so on startup or first installed, from air trapped in the valve. If it's air chatter you have, you get rid of it by openning the bleeder or opening all, or as many zones as possible, to run the air out by increased water flow.
Now humming...
The BRS 1.1 pumps are quality built pumps that last. They sell the same configuration as 50 ml/minute pumps by changing the gearing, but these just run too fast for the plastic gears, and die too quickly....I'd never buy the 50ml pump. However, if it was me, I'd simply double up the 1.1's...
I first off wish to commend @Mark_C for his progressive thinking and club dedication. If he was running for any Board position, he'd have my vote!
However, I still question the selective following of club rules. I notice multiple "Member's Group Buys" occurring here in this forum that...
You state that the tank is sitting above the dishwasher. Dishwashers have heating elements that most likely make that counter top fairly warm. I'd move the tank so it's not over the dishwasher.
It depends on your nitrate levels....and I simply use the NOPOX instructions as far as dosing:
Measured Level (ppm) ....................Daily Dose ml/100 L (25 gal (US))
NO3 above 10 ---------------------------------------3
NO3 above 2.5, but less than 10 ------------------2
NO3 above 1 but...
Where are you finding 37% vodka? It wouldn't bother me....I'd still use the original amounts and assume it's 40%. If your anal, with vodka at 37%, and vinegar at 10%, you'd what to use the following formula to exactly match the published percentage:
Vodka (37%) - 405 mls
Vinegar (10%)...
First off welcome!
And YES, you are correct in your dilution. The common vinegar found in your local grocery store is 5%. With the stuff you have at 10%, you only need to use half the volume, and make up the difference with RO/DI.
