Check with 2FarNorth (Jim) a reefer U.P. here just tore down his setup and may have a unit to sell. Post your lights in our selling thread too! Maybe you could trade your lights for a RO/DI unit.
@binford4000
do you mean DI (deionized) water? Just checking because that's different than distilled water. DI water is easier/less costly to make at home with an extra stage after RO.
Also if I could point you to one of our sponsors,
@AquaFX
(http://www.aquafx.net/) who also make very nice RO/DI filters.
No I did mean distilled water. Reefer has no means to get R/O DI and has been useing straight tap. Recommended distilled tell R/O unit can be purchased.
update: 12/2/13 tank at 40ppm nitrates I've been doing 10% water changes and using microbacter 7 with reef builder. It's definately showing results. Thanks all.
