My other corals (Zoanthid's, Mushroom's, Duncan's and kenya Tree) seem to be doing great. The Zoa's are growing new heads and the Duncan eats a lot.

I did a 15% water change on Monday and my salt is at 1.025, PH 8.0, Ammonia 0, Nitrite 0, Nitrate 0 and Phosphate is at 0.

I use RODI water and my TDS are 0 in the storage container (Brute trash can). I do have a clean water sump pump and a drinking water hose in the can to pump out water at all times.

Do you think that could be leaching something into the water?

That could easily be. You have brass fittings in the hose, and other metal fittings and parts on the sump pump.

Corals are very sensitive to any metals in the water, and salt water is highly corrosive.

Ya looks like brass. No good, must remove it pronto & dump all that water, start over & do a good water change this time without the brass/copper poisoning.

It is just rodi water in there with no salt but I did not have a problem until I added the pump. I will try that and see what happens. Any better way to get the water out of the trash can and into a 5 gallon pail?

Also, would copper show up on the TDS meter, because the water the container still reads 0?

 

[saltfan]

ya just dip the 5 gal bucket in the trash can.

In am also little confused and according to me the copper must show up on the TDS meter. Otherwise this would also be an another problem.
