Looking for the black, where did you find the clear?

Sorry LR for jacking your thread:twised:

As for your issue of crystals on the bottom of the tub / tank put a couple small power heads near the bottom at each end pointed towards the bottom.

no worries hijack away we can turn this thread to teaching your clown fish to pole dance of your favourit sps coral.. as long as its informative have at it. lol

i was thinking a closed loop style mixing station with the outputs pointed to the tank bottom drilled into the bottom of the tank to reduce cost of purchasing powerheads. float valve from rodi to keep constant water level between water changes. some sort of chamber to hold the salt to pre mix then dump into tank in hopes of reducing teh scum on bottom of the tank.

in the process of drawing out a plan off attack. will also need to drill a spout to dump premixed water into buckets to the two tanks.. with possability of pumping it from basement to the upstairs from under bathroom sink.

curse you finished basement and drywalled ceilings.

Both Edmonton fastners & Calgary fastners stock it.

Add some loc-line with fan nozzels to the closed loop then you can point them in any direction you want. I got a bunch of loc-line off e-bay REALLY cheap.

Cool maybe Red Deer Fastners can get it or have it too.

There is a product called "EZ-Clean" made by Deltec that works really well. Its just a powdered from of an acid that you mix with water and its aquarium safe.
