Who Gives A Fish Forums

Thanks for all the advice, everyone. Gonna stick with aged tap water, up the water changes, and keep the lights low. Fingers crossed!

After months of waiting, my discus pair just laid eggs on the driftwood. I've got a 75 gallon tank, pH 6.8, temp at 84°F, and a sponge filter running. Any tips to maximize fry survival? First time breeding discus, kinda nervous.

If you're still worried about residue, consider running a polyfilter in your filter. It's designed to remove a wide range of contaminants.

First, rinse the tank thoroughly with dechlorinated water. Bleach and Harpic contain harsh chemicals that can linger. Use a 1:10 vinegar solution to scrub the residue, then rinse again. Test the water for chlorine and other contaminants before adding fish back.

If you're worried, pool filter sand is a safer bet. It's uniform, pre-washed, and designed not to mess with water chemistry. Costs a bit more, but saves the hassle.

the sucker fish looks like an albino chinese algae eater to me.

as for the others, they're a mix of cichlids - there are just so many varieties out there, it's tough to pinpoint the exact ones from just pics.

**** edit - didn't catch that you already mentioned they were cichlids, my bad

You're telling me the ex1200 is already overkill for a 240l tank, so adding another one would indeed be excessive. I mean, what's the point of having that much filtration power in a relatively small tank? If you're experiencing some sort of water quality issue, throwing more filters at the problem ...
