Will anyone use these test strips? I bought them then got the API Kit & no longer have a need for them. They wanted like $5 to return them and I bought them for $8-9. I have Tetra EasyStrips 6-in-1 Aquarium Test Strips, 25-Count & Tetra EasyStrips Ammonia Aquarium Test Strips, 25-Count. Just make an offer on them. I think it'll cost about $3 to ship.
