Started a nano tank for my girls' GSP. want to make room for some torches and sps. its roughly 35 long 9 and a half tall and 8 deep. i have a reef 90 on it. will eventually add another once i upgrade the light on my main tank. it will just be GSP and a toadstool. i got some rocks coming this week and will make two arches of some kind to connect to each side of the GSP colonies. i'll have a nero 3 on one side and maybe get small tunez for the other. still debating on weather or not to keep the filter. i will have to change the sponge on the hang on filter every 3-4 days. im thining i might just do a 1 gallon water change instead. don't like the look of the filter. i got a piece of acrylic from tap plastic for the back to hide all the cords. each GSP colony is about 5x6 inches so it freed up quite a bit of space in the other tank. will be on the look out for a smaller heater and auto top off. but no rush for any of that cept the light. i will have to make some kind of custom bracket to hold the lights since i don't want to drill into the cabinets. There is a small gap in-between them that i ran wire through to hang the 90. if i can find a cheaper slimmer light, that would be great but not huge priority
