First water test tank has been established for a week. Water appears to be a bit murky. Any words of advice to help clear it up?
The tank's been set up for a week? Which method are you using to cycle the tank??
just the planted cycle.. i dont have fish yet though
What is the substrate, and what is the filter and presumably it is running? And what is tank size (gallons)?
its a 29gal,l topfin 30 filter, foam filter media, Super Naturals black sand substrate. I added root tabs, not sure if you have seen that post or not. today is day 6 in the cycle and I still can't see through the tank (from side to side) not sure if this is normal. Once I find my camera I will post pictures.
Oh and plants, as of now I just have Amazon Swords x5
What do you mean by murky? What color is this murkiness? o.o
Well, it could be a couple of things from what you've told us. First (hopefully) the substrate; I say hopefully because if this is the source it will clear without trouble. I asked about the filter because that should help it to clear.
Second, could be a bacteria bloom, common in new setups. This will also clear on its own. This I would think should be white though, so probably not pertinent here. Water changes would make this worse, or at any rate it would not clear as quickly as leave it alone.
But more likely, Third, if it is really more green than brown then it is likely "green water" which is an algae bloom that occurs when light and nutrients exceed what the plants can use. And without fish CO2 will be minimal so the plants are held back by that shortage [the law of minimum I've mentioned elsewhere], this nutrient carbon is not included in root ferts. Working on the assumption this is the cause, reduce the light. You have swords, so 8-10 hours a day light on, use a timer to be consistent; and a couple water changes. These will help clear up green water provided the light is reduced as well. Cut the light back gradually, e.g. if it is on for 12 hours now, reduce it to 10 for a week or two; if that doesn't do it, reduce it another hour. Rather than all at once.
