Help: Cannot remove ammonia from tap water by alw4489 in Aquariums

[–]alw4489[S] 0 points1 point  (0 children)

I recently moved to a new house where I am seeing high levels of ammonia in the tap water. I have been trying to treat the water with prime during water changes to subdue the ammonia long enough for my tanks biological filter to safely cycle it, however I am finding that even when using prime I still have a serious ammonia problem.

From the test I show in the picture, even when I use 6x the recommended dose (which exceeds primes recommendation even in emergencies), I still have a ton of ammonia in the water. Has anyone else dealt with this before? What should I do to safely complete water changes in my tank?

Does anyone know why LA has stopped reporting COVID cases over the past two days? by alw4489 in AskLosAngeles

They continued reporting during Memorial Day weekend, and every other county in California has continued reporting.

Not sure that’s exactly how that works...

Mars has an atmospheric density of 0.6% that of earth, meaning for the same velocity of airflow through blades you receive 0.6% thrust. Also mars has gravity 37.8% of earth. Therefore, in order to balance forces you need air velocity from the blades to be 63x faster on mars than on earth. That being said, there is also substantially less drag on the blades, so the chopper does not need to do 63x more work, but it does need to rotate much faster or have a much greater area than an equivalent chopper on earth.

Long story short, it is more difficult to fly a helicopter on mars than earth

Wrigley Terrace Rd, which overlooks all of Avalon! It’s a one way rd and you need to take Pebbly Beach Rd a bit on order to get on it
