Those are the walmart 5gal jugs. Depending on how I am feeling I either use my RO at home and hook it up under the sink or I run to walmart for 1.88 a 5 gal (Walmart is 2 blocks away and on my way home).
Yeah when there is sales I stock up, think I have the same $$ invested in product as I do shrimp.
I had 48" Dual T8's, but I am still working on how to mount them. The racks ar 48" and the light fixters are just over that, so I have to drill into the sides or run hooks through the cement board. I am ok with all the clip on CFL's right now, water changes are easy! Takes about 20 min
What you dont see is the 4 bags of Africana, 2 bags of Amazonia, and 4 bags of DRL I have for the next set of tanks!
