I am keeping a fish-in cycle log in the habitat arena here, and realize perhaps it should have been posted here.
I am starting this thread because I am ecstatic and so is Zen.
Long Story: We had a Hydor 50 watt in a five gallon tank and unbelievably it would not keep to temp so Zen was subject to 75-77 degrees or less (it varied with room temp and would NOT keep up) and Hydor itself (I called them) would not honor warranty unless heater was sent back (you can imagine how I did NOT like this).
So in desperation I ordered an Eheim Jager, also 50 watt. It arrived yesterday when i wasn't looking (earlier than tracking said but took forever ( I am talking to you, Amazon)). We had to subsist on the Hydor until the Eheim showed up. What a wait that was. It also compromised my ability to cycle the tank in a timely manner. And there is more about the Hydor slow shipping (as well) to begin with but don't get me started....
I installed Eheim. Here is the report. In the Eheim vs. Hydor wars, it is Eheim hands down. Tank is now to 80 degrees. In less than two hours. I thought the Hydor would do this same thing but it did NOT.
All of a sudden, Zen starts making moves!
I wish you could see the difference in Zen. I am loving this, just a few degrees means the whole world to him.
He is active, opening fins more than I have ever seen, and he is OWNING his tank....exploring every bit, checking out everything, completely inquisitive, and I swear his coloration is changing.
I waited way too long to get Eheim, I ordered it after realizing Hydor would not honor warranty unless I shipped it back, it was a comedy of errors, and i live in a rural location so it took a long time to repair Hydor mishap. I ranted a bit in my cycling thread in this forum. Very upset to say the least.
The Eheim is MUCH larger than Hydor, but at this point I care not, because Zen seems SO happy. I watch closely and i can see his little eyeballs moving as he looks around. Big open fins. I am very happy about this change (as well as aggravated for the two or three weeks of difficulty and sub-par environment).
All now is good. Problem solved.
