Re: Algae and java moss won't grow
Growing plants is not that difficult once you grasp the fundamental basics of how it all works.
If we had a fish free tank then we would turn up the co2 to a high level & adjust the flow & light to suit, however, most fish would be poisoned at such high levels of C02!
So we need to compromise & adjust the gas to suit the fish.
We need to distribute the C02 at just the right flow rate within the display tank too, as a guide look at using a filter or pump that operates around 10 x the tank volume per hour.
We need to get the C02 into a water soluble form & introduce it into the flow, that can be done in many ways - inline atomisers are very popular.
Once we have flow & C02 sorted then we need to offer some light, more light needs more gas & possibly more flow but we always have to think of the fish.
One way, is to turn up the gas over a week or so, very slowly & gradually until we see any signs of stress in the fish!
You have to be on the ball through & quickly turn back the C02 just a bit :?
Once we have found the right level of C02 you fish are happy with then we can up the light until we see good growth & no algae.
It helps to realise that 95% of the plants we keep, in fact, much prefer to grow out of the water & are grown that way until they reach the shops or your tank.
Of course any plant growing out of the water will have unlimited supply of C02 so we are already compromising!
