Mushroom help!?!?!

[locopride]

I have 5 mushrooms that were doing great but now they seem to be shrivling up, they come out some but not like the use to. I also have 4 towards the side of the tank that do great. I have PC lights that hit the water direct.(there is no glass canopy). I do a water change once a week.(5gallons) I buy my water.(R/O salt and top off with R/O fresh water) Does anyone have any suggestions?? Please help they were doing great for a month!!

Has anything been picking at them? Has there been a change in your water parameters recently? Do you add supplements to your tank? Hopefully there's nothing really wrong with the colony and they'll perk up soon. Sometimes they close up a bit, sometimes they're very very very open.

we had some mushrooms shrivel up and eventually died, we put it down to the temperature of the tank as it was sky high but it could be wrong PH etc.

I have my clean up crew (about 20 blue legged crabs, 2 scarlet crabs, 2 turbo snails, cleaner shrimp, and sand sifting star), 2 clowns (percula, and tomato). Supplments, i add trace elements once a week, calcium when needed (i test before i add), Pro-buffer dKH (i test before adding), and i feed zooplex. pH-8.3, ammonia-0.00ppm, nitrites-0.00, nitrates-0.00, calcium-450, dKH-8.0, alkalinity-2.86meq/L.
Is there anything else i should test for?? the only change in water parameters, maybe alkalinity.
