The test![]()
Do you do your test over the tank?
How do I get allll the water out? and someone said that i should throw away the gravel and filter media becuase of the mercury in the test?
I picked up a gravel siphon for about £5 from p@h and its a rather large one, quite a fast flow rate can empty my 60l one in like 3 minutes I think. I think the issue is whether your filter media may have absorbed or had some of test chemicals cling on to it.
Is Mercury really one of the ingredients? I'm impressed, I played with mercury one day.... was so much fun![]()
