just wanted to add these to the list. ive had an 802 for about a year now and still works great. also the 402s really blast. ive added "other" types of pwr heads to the tank and havent been happy with them 1 is 2 mths old and quit already its called a pro 2, after buying it it wasnt that strong to begin with. also adding another type cant remember the name its not bad but not as adjustable as the hagens. i do have a maxi jet and am happy with this kind as well, had this for a year also. never had any problems with that still as strong as day 1. does anybody run the hagens and maxijets and are they as happy with them? i thinking about dumping all the other ones and go with the maxis and hagens also if i ever set up another tank i wont go with anything else.
