I've got 2 Twinstar Nano+ for sale. $50 each.
These models retail for $140.00. Both reactors need cleaning as the micro-bubble output isn't as full as it should be. I'll include a half package of the calcium cleaner to the first buyer. Still have original packaging and all parts. Both units work, but the reactors need to be cleaned for full output.
PM me to purchase. Shipping $12 via USPS.
