I now have a 75gl.
It came with a Fluval 300 G6.
I hate it.It is constantly shooting tiny bubbles and I find is not keeping my tank clean
like the Bio's.
I am new at the saltwater experience so please bear with me.
Should I continue on with the canister filters or should I get some thing else,if so what ?
Can you recommend a good filtration system that is easy to use ?
Some thing that is reasonably priced.
I have done everything I can to fix this problem.I know there has to be an air leak some where
but I can't figure it out. Any input would be greatly appreciated.
Hi,
I used a fluval canister for many years, and never had any problems...not one. I mean an air leak ...would mean a water leak...there is no air supposed to be in the canister at all, it's sealed tight, and the tank water flows in and then back out. Once in a while when the canister is first cleaned and restarted there are bubbles that are released, but as the filter continues to run, after a few minutes, the air is completely expelled and the bubbles stop....
It is possible that if the water is entering with such force
above the water surface...it would create micro-bubbles as it hits the water. My HOB does that, the little water fall is above the surface and slashes as the water enters the tank...it makes micro-bubbles, but not that much to be concerned with.
Have you replaced any of the canister parts?
What kind of media are you using? Mostly the tank is kept "clean" by the CUC (clean up crew) consisting of snails, shrimp, bristle worms, serpent/brittle stars, and crabs....even certain algae eating fish.
The canister only removes large floating particles, and if you run carbon, it polishes the water and would remove toxins that the coral shoot at each other (chemical warfare). The beads are used to create surface area for good bacteria to grow on, and convert waste into nitrates. with live rock, you really don't need the bio beads. You can run Chemipure for removing phosphates...the media choices are there to help you with what you are trying to control.
A nice HOB a C4 Fluval brand is what I use on my 56g, it's pretty good filter, but it's rated for a 70g...you could run two HOB filters. For that price you can replace the canister with a new one....I also liked the Cascade brand, but to be honest, I liked my Fluval much better, it was easier to get parts and to maintain.
With HOB filters, swapping media is so much easier then cleaning a canister filter.
If you have your tank drilled, a sump system is the best option. I have a great sump on my 90g, but the lifter pump to keep the CPR overflow going is such a pain in the butt, I'm seriously considering going with a couple of HOB filters for that tank too. I just ordered my 3rd lifter pump, and I was using the prefilter...they just give out and get tired, and the next thing I know...the overflow isn't doing it's job. I have come to the point of believing that if a tank isn't drilled...pass on a sump system.
