I have 2 pinpoint marine ph meters. one is the small portable one, or you could mount it. the other is the larger more expensive model you can attach to a bubble counter or reactor. It still retails for around 200 bucks. They both need calibrating but the probes have been kept in a solution. looking to trade them for Radium 250watt, 20,000K single end (screw in) bulbs. Even trade as long as they are good bulbs and hopefully you have the receipt as to when you bought them...New is better and I will throw in a little cash to boot, which is still a great deal considering what both these meters cost and they aren't 5 months old..i never even used the larger Ph meter because I decided to go against using a reactor...I'm in sc 29655 is the zip code....I really really really need these..my bulbs are worn out ..So, please help me out...;p
