OK, for the life of me, i simply can not figure out why i cant keep my coral alive. Ive alternated locations, amount of flow, and NOTHING is keeping these things alive. Ive lost a green tree nepthia, and some other leathers, and seem to be losing a Xenia and even some button polyps (and supposedly any jackass can keep these...) Specs... 30 Gallon, Current light fixture- total of 128 watts 2 hang on the back filters, coral life protein skimmer, 2 koralia 1's, a marineland 160 canister filter 30lbs live rock, 20+ lbs crushed coral substrate 2 perc clowns, lawn mower blenny, and a 6 line wrass. ~10-15 various hermits (red/blue legs) ~10-15 various snails (astrea, and god knows what else..) and Peppermint shrimp and a sally light foot. I have been using r/o water so thats not it either... I dose phytoplex ~3 days, along with purple up every (other) day, and a supplement called microbe lift about 1-2 times per week. pH-8.3 Nitrate (ite), ammonia, phosphate 0 alk- 10 dKH, 179 ppm KH/GH calcium- 450 iodine- .06 temp- fluctuates between 76-78 depending on the time of day water changes- change 20% monthly, test weekly and adjust as needed The only hint that i have that may be the culprit is the fact that before each coral died- it appeared as if some form of brown algae LIGHTLY accumulated on parts of the coral. Ive increased the water flow once i witnessed this and still nothing... -On another topic, any recommendations on cutting back on my green/brown algae which accumulates every couple days on the glass, but is easily wiped off? HELP!!
