Thanks guys, good to be back. Hopefully soon i will set up my Elos again.
For this little tank i run AquaClear 50 hob filter, filled with bag of carbon, purigen and siporax media. Also running Macro -Aqua 60 skimmer. I do 2 gal. WC weekly , also clean the media in filter, to get rid of all uneaten food that gets pulled there. Once a month i do bigger WC like 50-80%. This keeps my parameters within acceptable levels. On small tank like this it is easy to do WC . I keep my temperature 72F. Have 3 small fish in there: tailspot blenny, neon goby and ORA masked goby. One porcelain crab, couple of hermits and 3 nassarius snails. Lighting is led fixture that come with AIO 3.6 gal. Petco brand tank. Only enough light to illuminate my tank, but not enough to grow anything, including algae.
