So about 3 months ago I decided to try out a new approach my brother has been working on with his 210.

First let me give you a break down of the tank then what exactly im doing.
150gallon tank
40 gallon refugium
40 watt UV sterilizer

Stock List:
Fish:
2 mated true perc
maroon clown
yellow tang
sailfin tang
kole tang
4 damsels
bi-color angel
coral beauty
3 scooter blennys

inverts:
purple lobster
coral banded shrimp
condy anemone
maxima clam
croecea clam
2 pencil urchins
blue linckia
orange linckia
30-40 assorted hermits
40-50 assorted snails

corals:
large mushroom colony
kenya tree
star astria
digitatus
green slimer
cup
devils hand



Now here was the plan:
I nottice i need to replace almost 2 gallons of evaporated water each week. (which sounds a bit high to me) but the top of the tank sits under 800 watts of 20,000K so i guess a lot of evap. is expected.

Any who i've got 340 lbs or live rock and the sump has enough macro-algea to fill a dump truck. I got tired of keeping to have to fill a bucket with RO and re-fill the sump.

I set up an auto-top off and aqua doser. high flow.

At first using this system seemed scary to me and i did lose a clown fish, however i don't believe it had anything to do with the tank. There was a small nitrate spike at week 6 however it was taken care of in about 3 days. I have tested water params every 3 days since this experiement has started. At first the water params at the point of what would have been my water change started to go a little bit off, i did nothing and they took care of themselves. my water quality has not gone off the mark in about a month now.

I will let you guys know when exactly my water params do take an actual turn. Also believe it or not there is alot less algae then i had first expected. the snails and urchins seem to be taking care of the algea issue. and the high flow seems to keep anything from really STICKING.
