Thanks for your responses. Now that I know it's BBA I'll reduce light intensity and see if it helps.

I have this algae on and off, attached to basalt and HOB's water intake. It seems to only attach to dark surfaces. Just wondering what type it is?

Thanks for the links. The Lake Malawi is an impressive doco. Yet to watch the coral reefs.

Not many members use the Fluval U series internal filters, so you aren’t likely to get many responses. I have a U3, the next size up from yours, but only used it for around 18 months or so. I had to clean it every week so is a bit of a chore. I replaced it with a much simpler Eheim Pickup 160...

Your workplace uses a very high concentration of salt, could be the reason why it’s added over 3 days (not to shock the fish too much) and do water changes removed salt the following days. This sounds more like a salt bath. I think most members here use no more than 1 to 2 tablespoons of salt...

I can give her another "like". Cats are very smart. If a cat doesn’t want to be surrounded by 4 walls of glass it will get out in a flash.

Welcome to TFF. I can’t tell what the problem is from the photos, although the video seems to be a fish with bacterial infection. A general comment is that it’s difficult to keep fish healthy long term in a small tank because good water can change to bad and then to very bad very quickly in a...

If you really lose 5 gallons of water every 2 weeks through plants’ capillary action and transpiration and you siphon out another 5 gallons, that would be more or less like changing 10 gallons of water every 2 weeks or 5 gallon per week. Simply put, capillary action will pull water and...

And another thing, I only run the filters to circulate water and oxygen levels in the tank. Don't really care much about the bacteria in the filters as my ammo and nitrite are always zero with each filter running 12 hrs a day. Do bacteria die with filters running 12 hrs a day? I have no way of...

The 75 does a pretty good job, although I add fine wool in the filter in addition to the coarse sponge that comes with the filter. One thing with the tydal is that if you hear guggling sounds from the filter, it's because water in the tank is not deep enough.

I have two 240L tanks, each tank runs a Tydal 75 during the day and a 55 at night. I'd say a 110 on your 70G is plenty, but have you seen the size of the 110? It's close to foot long! Compared with the 110, the 55 doesn't pick up much debris as its intake tube is not deep enough.

If the info provided by the manufacturers is correct, your current light has the right colour temperature of 6500K and the brightness is 1050Lm if it’s a 18” - 24” long light, or 1500Lm if it’s 24”- 30” long. The Nicrew has the same 6500K and the brightness is pretty much the same as your...

Does your filter come with an instruction manual? The bit below should help.
