I got 8 frags and lost 7.
This is quite unusual since I have never lost any frags that I got from other hobbyists in frag swaps except for one frag that I got in one of the Nashville swaps, which arrived in a stressed condition due to the cold weather.
I guess I need to take an inventory of my powerheads. When I transferred rocks from 120 to 180, another powerhead failed in a large tub of extra rocks that came out from 120 and caused ammonia to spike in the tub. I was not going to use them in my 180, but I did not plan on holding them in my living room for another two weeks to let them recover from the mini cycling. Then, the pump on my ASMG2 failed and shocked me while I was rearranging rocks in 180. I suppose that I will be replacing a few powerheads soon....
There's always something that requires attention in this hobby. My TDS meter is reading 20 ppm on the outlet of my DI cartridge. The color change resin has not changed its appearance much and I have been wondering about this. I had barely enough DI resin to fill up the cartridge during the last change and the resin settled. There is about 1/2 inch of open space at the top. I am afraid that water is channelling through the resin. Should I put some more resin to top up the cartridge or should I replace the whole batch of resin? Any suggestion?
Sorry, JimW, I didn't mean to hijack your thread.
