I got a 90 gallon with a +/-25 gallon refuge sump. I am not running a skimmer, I don't have any fancy stuff. I have a mixed tank with about 70 percent softies and 30 percent SPS and LPS. I have 14 fish in there....yep 14...
2 - Regal Tangs
1 - Japanesse Swallowtail Angel
3 - perc clowns
1 - GBTA
5 - medium sized Chromis
1 - six line Wrasse
1- golden headed sleeper goby
I have about 160 lbs. of live rock....mixed fiji and tonga. 60 lbs of live sand...and I mean live. My sand is full of feather dusters, bristle worms, spagetti worms, etc. The backs of my rocks are coved in mini feather dusters and worms. I supplement this cleaning crew with:
4 - extra large mexican turbos
1 - zebra snal
3 - serpent star fish
1 - brittle starfish
35 or so hermits
The Refuge has a 5 inch sand bed with more critters and is full of cheato. Have to cut that stuff about once a week....need is now...lol. I have also put in about 35 lbs of live rock rubble and know that there are tons of mini-brittle and asterea stars along with the biggest bristle worms you will probably see in an aquarium. I recently tossed in a fist size rock of anthelia coral that is growing like a weed. I didn't want it all over my display. It is growing like mad.
I feed my fish in the morning a little flake or pellet. At night I feed frozen foods or chopped up raw shrimp. The starfish love that stuff.
I do not add supplements, (till recently, get to that in a sec.) I change 15 gallons of water every two weeks. and scrap the coraline every week.
The only reason I started adding and supplements was that my LPS and SPS corals were surviving buy not by any means growing. I have decided to add calcium / alk / and mag via the "Two Part Solution" method.
Oh....I don't run a skimmer, but I am thinking about it. The only reason I am thinking about it is that I don't want to have to change the water as often. But not sure where I am going with that yet.
I got happy fish, happy corals, happy GBTA, and everything else. I will keep it this way as long as everything stay well.....happy watching....
