I have two HK-2's and one HK-1 available. I have been using these in my tank since about July or August. They have some Coraline on them and I can completely clean them before shipping. RFS is I am going to Tunze 6055's with controllable flow. New, current pricing is $35.99 for a 2 and $39.99 for a 3. I am asking $27 for each HK-2 and 30 for the HK-3, plus shipping. Please no low ball offers, I believe these to be fair prices.
