I have to go, new job and new city. For sale as the system comes down. Some items might delay as I still have livestock.

Tunze 3181 algae reactor. 2 years old, in perfect working condition $125
Tunze 9415 Skimmer 3 years old (kind of) $400. This is a beast and the most reliable and consistent skimmer ever. Pump replaced this spring, so it is just a few months old.
Avast Marine Kalk Stirrer 6 years old. Very sturdy and reliable. $100
Aqua Illumination Hydra 52 lights (3) These are NOT the HD type, older type requiring controller/Apex module. $100 each
ApexEL about 3 years old. Temp and pH probe included, but the pH probe is old. $250 ( cannot sell until more of system goes)
Dr. Bridge KH Guardian 4 years old, but working perfectly. All upgrades, hardware and software are done. $200

PIX upon request.

It is the K1. Shipping will be dependent on how you want it sent and insured. We can take the discussion private. I will include about 1 lb of Kalk/Ca(OH)2

Includes the EB8 as well. I really think the pH probe is completely shot. I cannot ship this for a couple of weeks though, until all the livestock is gone.

I do not have any working probes but they are fairly cheap to replace. Unfortunately, the packet of reagent I had sprang a leak in storage so it is no longer available.

Was the reagent for the KH guardian? How much for the unit excluding that?

It was reagent for the KH guardian. Without that I can do $200 shipped to Seattle. If you would like the PM1 it would be $250 and includes all cables necessary between the KH Guardian, the AIM unit, the PM1 and then the aqua bus of the Apex unit.

I have a dead, dried out pH probe. I have heard that some people can revive them, but I am dubious. I can throw it in if you like.

I'm very interested. This is the unit that tests only, does not dose? How have you liked having it? I feel like it would be convenient.

This is the unit that only tests and does not dose. I have liked it very much. There is a very supportive facebook page where people will talk you through any difficulties or upgrades you might need. They also sell the reagent at a discounted rate if you buy in bulk.

Using the PM1 I tied it into my apex so that my Kalk level was "always" on display. I use the quotes, because the KH Guardian tested every 4 hours, so it held constant for 4 hours after the test. You could use this reading to have some other pump dose, and I did try that at one time, but then I just found a Kalk reactor much easier to gage, and I added Kalk to the reactor if the KH was dropping at all.

Thank you for the info! Sorry for all of the questions.This was a concern last I looked into these units; does it also have a personal wifi router on it? Like the little TP Link Nano wifi bridges? I don't believe I can hardline it for internet connection. Or does the AIM module and being connected to the Apex remedy this issue?
