It is actually really well built. In all honesty I was expecting crap for 23 bucks. It is good and solid with John Guest tube connectors.
I am going to use it to dose Phyto etc.

I would give it a 9 out of 10

Even the high low water alarm seems great. Paid 4 bucks. Figure I can find some use for it at that cheap of price.

if you run 2 different return pumps for various times of day then..

You wound run into problems with your drain system depending on how its designed.

for example if you have a herbie design and its set perfectly for the pan250. when you switch to the smaller pump at night your drain will lose full siphon and your sump level will raise.

Usually herbie or doso drain designs are matched to 1 return pump by setting the gate valve on the main drain. So with this idea i think you may have issues , thats unless i am missing something ?

I never thought about the Herbie....I was thinking sump level might change and cause issues with the skimmer ..

I have not used the Herbie, but plan on it for this tank build.

I correct my self. I will be using the Bean Animal. I went to is own site to see what issues I might have with two pumps running differently and it seems that it will compensate for variations is the GPH of a pump. Not sure if it will compensate a large amount or just a little variance in amounts of GPH.

Anyone know the tolerances of what it will compensate for?

It looks like you have dual RW20s (20000L/hr) not dual WP-20s (no such model - closest is WP-25s (6500L/hr)).

You are correct my friend.
The WP is the old model I have been reading about everywhere and forgot I have the new RW model, as they did not send any fricken instructions in the boxes explaining how the presets worked and I had to search youtube etc.

As a side note to anyone. I ordered the apex controller, for the RW-20s from them too and they did not send the power supply with it. They now say it does not come with one and that it states that on the website. I can not see that it says that anywhere....

Not a biggie, but who wants to order something without the power supply. I can not even find anything on the website as to what power supply is required except that it requires 24 volt....
