I'll personally never buy another filter. It's all way over priced. The only part worth money on them is the pump. And if you buy just the pump, you can get tons more flow for a fraction of the cost. DIY your filters and you won't deal with any of the remorse.
I dont mean to sound rude in anyway. Haha. But store bought filters made me feel like a slave and always gave me buyers remorse...then I watched a bunch of DIY on youtube and realized what extremely simple devices they are.
Biological filtration is EASY to achieve...so, imo
, any high dollar your spend should be for mechanical filtration.
My Eheim cost me $140+ and is rated 80gph. Thats just crazyness! You can literally get a pump rated 700 gph
I just made a filter with a $20 pump that, I would bet money, could compete with my Eheim, if not perform even better.
done ranting. LOL. I just hope it helps.
