Ok, tank has finished cycling and I'm almost ready to do a complete water change with mineralised RO water. I've got a few questions before I do though.
I have Dragon rock in the tank and I believe that's the reason my TDS is so high, currently around 350ppm. Will the rock always give me a high TDS reading? Must I remove it to have any chance of keeping shrimp? I like the arrangement at the minute and I'd prefer to keep it if possible.
When I'm using the RO water and I add the minerals, do I go by the reading on the TDS meter, say at 150ppm, or do I measure the GH/KH and stop when they reach an acceptable level?
I have, or had, 3 guppies in the tank, I now have 8! I'd like to keep a few as long as they won't decimate my shrimp population. What do think would be the maximum amount of small fish to keep in a 30L tank with cherry shrimp?
The tank looks beautiful only a month after setting it up. The plants are growing like the clappers, I've pruned quite a few already but as I planted the tank heavily in the beginning I've no room to transplant them so they're supplementing my Cichlids diet, win win.
