Hi Guys and Gals
Been a while since I posted. Just started up a new tank (upgrading from 40g to an 80g) and am having a few problems.
Hopefully someone will be able to help out with some advice.
OK tank details
Aqua One Regency 120 (Deep)
Dimensions Tank: 120W x 46D x 70H cm
Water Capacity: 300L
Lighting: 4 x 54W (2 x 6700k 2 x 10000k)
Filter is Aquis 1200 (supplied with tank)
Hydor Koralia 2 Pump in tank for extra water flow
Pressurised CO2 with a Rex Grigg Inline Reactor
PH 7 KH 6 GH 7
50% water changes and EI dosing
All up and running, cycled for 4 weeks and just added a few fish and all going well from that front.
The problems I am having are to do with the CO2 and water flow.
I am getting a lot of bubbles from the spray bar (co2) which are not being
dissolved. I started with 1bps into the reactor but am now up to such a high number of bubbles that they are uncountable (which probably accounts for the bubbles being forced into the tank). The problem is that the CO2 levels in the tank don't appear to be going up. I have a drop checker and it is constantly dark green / blue. Before I put the fish in I tried upping the CO2 to ridiculous levels to get the drop checker to change to yellow (just to try and prove to myself that it was working correctly) but with no success. I am concerned that the co2 is not being dissolved in the reactor and that the flow into the tank is not distributing the water efficiently.
The outtake is bottom right at the back of the tank.
I have tried several different placements for the spray bar into the tank
Left Side bottom horizontal / Back bottom horizontal / Back top horizontal
But with only minimal differences in the CO2 reading.
Does anyone have advice on placement of the spraybar / additional power head ? Should I be using a spray bar at all or maybe a lily pipe ?
I am starting to get quite a bit of hair algae on the plants (especially, but not limited to, those to the right of the tank).
Any help, advice, criticism, pointing out of stupid mistakes would be gratefully accepted.
