Really need advice.
I have posted before about my 30 gallon tall bow front tank. its 4 months now and i am running out of patients and money.
I cannot keep corals, shrimp, crabs, snails an numerous fish. They die in my tank, and fast, not more than a day. Only fish i amble to keep alive are 2 clowns and one yellow dart fish. They are alive but seem listless, swimming near tank bottom.
It was suggested before to add more lighting for the corals. I did, i now have 2 sets of T5HO. first soft coral went into the tank and never opened again.
Inadequate water flow. So went to larger pump and a second supply line. Lots of flow. Invertebrates all dead within a day. coral dead too. Yesterday one coral beauty and one wrasse dead within 6 hours. OK, low oxygenated water possibly?
I added a third power-head to the tank to move around the surface water. No change.
Water perimeters are within line. ammonia showing 0 but i am getting skeptical. no nitrite, no nitrate. PH level around 8.2. KH
at 12 dKH
. Calcium at 500mg/L. Salinity 1.025. tmp. 78.F
i have a sump of 20 gallons with rubble rock and started my tank with live rock.
Something drastic is happening. everything dies fast except my clowns and dart fish.
i am attaching pics for reference purposes. My most recent dead fish can be seen behind spongebobs house. dies last night.
