can try to move your CO2 diffuser to below of your filter intake, in this case, CO2 will be sucked into filter mix and flow out and be distributed.

Any bros can advise, my c02 diffuser is on the left side of the 3 feet tank. Filter is canister filter dolphin c700. Filter outlet Rain bar is across the 3 feet tank. Filter Inlet at opposite end of the tank of c02 diffuser on the right side of tank. I have a feeling c02 only remains on left side of the tank where the diffuser is and not evenly distributed across the tank. Light and c02 8 hours daily.
Also I feel my tank is 3ft by 1.5ft by 1.5ft. Filter power is 1520l/hr. Seems like the dolphin c700 is an overkill. Fishes seems to be swimming hard. Should I turn the inflow and outflow tap a little to lower the flow rate?
There is an algae bloom on the glass of my tank at the moment.
2 week old setup. 15% Water change only once at 2nd week.
Fishes. 2otos, 2 puffers, 6 tetras and 10 mosquito rasbora. Lost 1 Oto so far. Only casualty.

I have read that the bubble will form up in the canister filter? Is it true?Originally Posted by fireblade
to me its ok...
I have inline CO2 diffuser which CO2 go directly into the canister then out no problem so far...
think up to individual, alternatively, get a wave maker to distribute the CO2 or put CO2 under the rainbar , that might helps too...
algae bloom during initial stage is common problem for planted tank, commonly due to ammonia rising up,
to minimize their bloom i mostly do Water change every other day, surface agitation to produce more oxygen, fast growing plant or surface plant. Usually folks didn't introduce fauna before it's cycled to minimize the casualty and expose the tank with more ammonia.
Surface there is also a film of oil. Anyone knows how to get rid of it?

Your tank is at a cycling stage,do 30% water changes weekly rather than bi weekly.
Do a siesta light cycle,eg..4 hours on 4 hour off then another 4 hours on. Total light period is still 8 hours but it is divided into two sessions.
you can actually lower the light hour to 7 hour and monitor the plant growth.
For the film of oil,it is a protein layer on the tank suface,place the out put of the rain bar right on the water surface to create agitation on the surface,it will help to clear the protein layer.
Use a CO2 reactor, it will be more efficient in distributing the CO2 around the 3ft tank.
What is a co2 reactor?

What's the best way to clear algae on the glass? Or should I just leave it alone and it will clear up by itself?

Its a system connected along your outflow hose which will mix the Co2 and completely dissolve it into the water before it exits out of the outflow pipe. The benefits are 100% Co2 dissolve rate (hence much less wastage), and it eliminates the fizzy bubbles floating around the tank effect that tends to obscure aquascapes.
Here is a video example of how it works:
A good quality algae scraper/razor is still the best and simplest item to use for scraping away algae from tank glass. Just have to roll up your sleeves and start scraping away.
You can also introduce algae eaters like otocinclus (they eat soft green and brown algae) or nerite snails (they eat soft algae and also green spot algae too) to help clean the tank glass too. They may not clear 100% of the algae, but at least can help to minimise it enough to warrant less frequent manual algae scraping. Their effectiveness still depends on the rate of algae growth though.

Where can I buy a c02 reactor? What's the price of a reliable brand?

You can get the ISTA Co2 reactor models from places like Seaview... the version i use looks like this:
It costs only around S$15+ at Seaview.
Do note that there are flow rate recommendations for different Co2 reactors (for them to work properly), the one i use is rated for 360 l/ph - 1,000 l/ph canister filters. So you need to be using a canister filter which has an effective flow rate within that range (closer to the top of the range the better).
Thank you all for the replies

Is my flow rate too high as well?
Sent from my iPhone using Tapatalk
1520 flow rate is more than enough to hook on ISTA co2 reactor.
Currently i am using 950 flow rate, i already feel it is super strong.
Hi bro dscheng, I meant should I lower the flow rate for my tank by adjusting the taps of the filter?

High flow rate is good as it helps to distribute the CO2 throughout the tank provided your fauna can take it and it does not uproot your plant.
Your current canister flow rate of 1,520 l/ph is good for the 3ft tank... if its too much flow and your fishes are having trouble swimming, then you can just adjust the outflow tap lower to reduce the flow accordingly.
If you plan to use a C02 reactor with that higher flow rate filter, go for the ISTA Mix Max L model, that one is designed for flow rates that range between 1,000 l/ph - 2,000 l/ph, it has a taller reactor chamber which allows more time for the higher flow rate to mix in the CO2.
Thanks bro urban aquaria. I am more worried about plants than fishes. If the flow rate is good for 3 feet by 1.5ft by 1.5ft then it's fine.
