I've been tempted to add a Red Wasp Fish. The tank is old (30 years) with a lot of pods and algae. Do you have to target feed live foods until established?
You should probably stop submerging them, wow.The real diatom motors are really garbage and don't last in salt water which is why I have 5 or 6 corroded ones. They also don't make them any longer. Even the motor I replaced it with are not made any more but it's easy to build a completely new unit with a much better design. I already designed it years ago. I may order the parts this week. It will cost about $100.00 to make a really good unit.
You mean they are not submersible!!!!.. Maybe thats the problem, especially when they are plugged in.You should probably stop submerging them, wow.
