When I set up my stuff in the beginning the prices were daunting for me because I am on a REALLY FIXED INCOME. However here I am 5 months into fishie ownership and I realized the stuff I had just was not cutting it.
My filter was keeping my tank clean , until it broke down. People always commented on how clean my tank was and it was great to get so many compliments.
I went out and bought a penguin bio wheel (make sure you get 1 size up from what you need). It was 60.00 and for me that was insane, justifying it was difficult.......
I had to do a hack job on my hood with a red hot butcher knife just to get it to fit LOL no perforations on MY hood.
And let me tell you, here and now. It is JUSTIFIED. this is the best . filter. ever.
His water is crystal clear and beautiful! everything is crisp and clean and clear! He has TWICE the energy because the water is so perfect now. It is so much cleaner that I keep staring in amazement at the difference.
So, if you are hesitating on the penguin bio wheels I say go for it! Good stuff.
