<span class="link_user">@Tylerjc713</span>, I use a large Tupperware type res. I don’t know max capacity. I just filled with 25 gallons and marked a line. I don’t top off nutes in between drains. I drain my res every 7 days and add new nutrients. I grow in coco coir so I don’t have to clean stones. I clean my pump when I drain every 7 days.
