Freshwater scrubber

[kerry]

I figured that was a soupy mess. I seen threads on some other sites and maybe here I dont remember for sure with nails and screws in with the filter media!!?? I could not see how rusty metal would do anything that was good for your tank. I was totally blown away with disbelief of this concept!

OK, here it is!! Finally enough growth to get a pic!!! I will be testing the water today after work for nitrates as this is the water change day for the 150G. I am not sure how much of a difference if any there will be in the nitrate level with only a little growth. Usually its between 40-80PPM in a weeks time so the test tonight will tell.

To me that looks like a screen that has just been cleaned.

This is my five day old FW screen. I just started this last Sunday night.

Needs more light.

I will add some more, I need to increase the flow to. Its hard to tell from the pic but the center is yellow like its burning the algae. I need more and bigger slots in the delivery pipe as it blasts past the first and middle slots and really comes out the plugged end slots in a larger volume.

OK, here is the growth after one week. I took these scrubber pics on Sunday afternoon but, the nitrate was taken Saturday. The nitrates have not seen any noticeable difference yet, as I figured.

Some nice growth starting there Kerry! Looks better than mine did on my first week! 8-)
Nitrates should start coming down in a few weeks time!

I have a lot of hope for it! It grew algae faster then my SW builds ever did. I have got my 660nm red LED's in and am thinking about supplementing some of the lighting with LED's seeing SM suggested more light for it.

Here some growth pics from the evening of the 5th, three days growth. Its looking real good. The nitrates have not climbed at all, they are staying around 40PPM. Usually by this time they would be well over 80PPM+++. I did not do any water change last weekend either. I hope to see them going down in the next few days as the screen growth is getting much better now.
