Auto Water Change System (Chemillizer HN 55)

I'm really excited about this injector that I ordered. I will be running all my water through a 3 stage filter then it will be injected with Prime and mixed with a pump called Chemillizer HN 55 1:500. I decided I wanted to try this system rather than have 2 50 gallon barrels in my fishroom.

I know of a person in the US that has this system. He is Li the owner of MonsterFishKeepers.com. I can set this so it changes water 24/7 or a few small changes every day. The Chemilizer is a better pump than the Dosmatic it uses a diaphragm rather than a piston.

Did my first water change with the new system last night. NO LEAKS

I have it set up to do 2 15 water changes for now till I am sure everything is right.

Well I woke up at 6am this morning to watch my first auto water change happen. The click click click of the Chemilizer was music to my ears. I will now set it to 4 15 min water changes per day. I don't need to heat my water when I do small changes like that. Here's a chart so you can see what's going on.

Just for the record this was a very cheap set-up to build (about $600 give or take a few bucks)

I have 5x75g, 1x55,1x40,6x20 and now that its up and running i will be hooking my 260 and my 125 up to it.

I will also be building a rack to hold my 55 and two more 75's right away. So I will be running 1055g on the system. I have more tanks than listed :D

Here's a pic of a few of my tanks. All my tanks have overflows plumbed to a drain.

Impressive set up. Two minor tweaks that you might want to consider.

1. Swap the crushed coral out with crushed oyster shell. Most feed mills sell 25 kg bags for under $20, and it's a more effective buffer.

2. If you only have to deal with chlorine, instead of Prime, get some bulk sodium thiosulfate.

There's a source close to you & it will save you a ton of money over the long haul.

Thanks for the kind words

The crushed coral is working fine

This is the mix I use

Batch #1

250g Sodium Thiosulfate

200g ethylenediamine-tetraacetic acid (EDTA).

1 gallon distilled water

5 ml (1 tsp) treats 20 gallons

I tested it up to 100x the strenth a couple months ago and I buy my Chemicals from I nice place in Denver. I have a couple other things I add but that's my little secret.

Before I had the system running I was going through a lot of Prime dosing every tank so I started making my own.

I only mentioned the crushed oyster shell as it's proven to be a far more effective medium for buffering. At least according to the late Dr. Leo Morin (the creator of Seachem) as well as a number of other reef keepers with chemistry backgrounds. Either way, if the crushed coral is working for you then I guess that's all that matters.

I'm curious as to why you feel the need to use EDTA? Do you have a heavy metal issue in the tap water there, due to the low pH? (as in leaching from pipes)

Copper pipes and lots of other goodies that crash my water. Victoria water is very unstable

I might try the oyster shells one day I know where to get lots on the beach

Staff from Chemilizer have contacted me interested in my set-up

They want to use my pics in a newsletter. Can you say excitedapen701.gif
