As far as your filtration, it sounds like you are running just mechanical, no biological. Do you flow through a lot of water? Since you are in a tropical area and probably don't have chlorinated water (?) you could just maintain a constant flow of fresh water, maybe 1/4 to 1/2 gallon per minute. If you do this, you could support a fairly heavy stocking level. Of course, if water is scarce or expensive this method won't work... In that case, you should look into adding some bio-filtration.
