Okay guys,
I read up about the importance on water current with SPS corals. So I decided to create the perfect setting for my size tank, hosting my SPS corals.
With having already one rio in the 1st chamber I purchased the rio 50 to go along side his brother the rio 90.
The end result is even more unified water current in my nano. I have posted 2 pictures from the surface so you can see the amount of agitation I get.
In adding the rio 50 I noticed that my back filtration chamber 2 and 3 performs better. The water level dropped again to the point that water from chamber 2 does not waterfall over to chamber 3. Take a close look at the picture with the two pumps and compare it with my other pic of just the rio 90, you can see a significant drop in water whereas with just one pump I was touching the surface ready to cascade into chamber 2 like a waterfall.
Instead it travels through the intended built water ducts below the surface. I'm very happy about that but more happy with the fact that I can see the small polyps that come out of these stony guys, it's really nice.
I am by no standards suggesting that you follow my lead on the Rios in chamber I. This is in fact my best practice for my intended corals which happen to be SPS.
Also because of much feedback regarding my moonlight only being on one side, I have inserted two 3/4 moon lights from coralife on the opposite side to compliment the tank and get a unified look of moonlight all over the tank.
Thanks for your comments.
Mike
